Stain was annoyed on how he was getting interrupted as Izuku was busy watching his sister who was down on the ground.
"Big Brother...is that really you?"
All Izuku did was smile at her, "Yeah, it's me lil Sis"
Mizuki could only shed tears as she heard Izuku said that but their little reunion had to be cut short as Izuku grabbed a dagger that was aiming for the back of his head and he turned his attention to Stain.
"So nice of you to be their for a family member but now you've only got yourself to blame for their death"
Stain said as he dashed towards Izuku with his blade in hand and went to slash at Izuku only for the boy to avoid the attack with ease and sent a kick to Stains way that caused him to be kept a good distance.
'This kid...is this his quirk? If that's the case then he's the same as the girl, both of them are powerhouses'
But his thought was cut short as Izuku blitzed towards Stain who had no time to react as he was punched in the gut, that sudden action caused him to be pushed that up in the air, Izuku meanwhile went towards the Pro hero and grabbed him which made Stain to sent multiple daggers at the boy.
Mizuki shouted for her brother to watch out but all Izuku did was sigh.
"It took him a while"
As Izuku said that, he jumped high enough with the Pro hero in his Arms as a blast of fire was seen that melted the daggers and turned them into liquid metal.
Stain narrowed his eyes as he looked towards the one who summoned those flames...and that person none other than Shoto Todoroki.
"Yagi, next time get to add in more details, because just having your location and nothing else made me late." Todoroki said as he explained that it took him a few seconds to figure out that Mizuki was calling for help, since she wasn't the type to send such a cryptic message wasn't like her.
Just then Izuku landed near Shoto whose eyes widen at the person who was considered to be deceased.
"Glad that you're joining peppermint, so how about you keep that noseless bastard busy" Izuku said as he lay Native down who thanked the young man.
Todoroki started attacking Stain, sending out ice that raised Mizuki, Izuku and Native off the ground and shooting fire at Stain. He also said that the pros would be there soon. The ice was shown to be a slide that sent Mizuki and Native sliding down until they are next to Iida, where Todoroki could stand over them all protectively.
Izuku smiked at how much his little sister got a friend that was this protective.
Izuku was by Todoroki's side as he said he'll help hold down the fort and try to take down Stain.
Mizuki warned both Izuku and Todoroki about how Stain's quirk used blood to paralyze people.
"If that's the case I'll just have to keep Stain at a distance"
He said which only caused a blade to come his way which was blocked by Izuku, using his leg to kick it away but that only caused a second blade to fly through the air and this left a cut on Todoroki's cheek. Stain leaped at Todoroki, but was blocked by a small column of ice. It sent his sword flying into the air, and Todoroki looked up at it. Stain used the distraction to try and lick the blood off Todoroki's cheek, but the boy forced him back with a wave of fire.
What Stain didn't know was that Izuku was up in the air and grabbed Stains sword and dived down with speed and went for a slice up the Hero killer, even with his quick reaction time, Stain still got cut but it was only a scratch from the arm, however it only made Stain to glare at the boy who just smirked.
"Maybe I'll keep this as a souvenir" Izuku said with a hint of enthusiasm in his voice.
Iida started demanding to know why Mizuku, her brother and Todoroki had shown up. He was the one who inherited Ingenium's name, so it should be his fight!
Todoroki calmly commented that it was strange that Iida would say such things, since he'd never known Ingenium to wear the kind of expression Iida was right now. He commented that Iida must have a lot going on behind the scenes of his family too.
Mizuki watched Todoroki fighting off Stain with Izuku keeping the hero killer at a distance, as she found out she could now move her fingers. Stain sliced through the ice in front of him and mocked Todoroki for being dumb enough to block his own sight of an opponent faster than him.
Todoroki tried to defend his actions, but was cut off when two blades sunk into his arm.
Stain leaped up and was about to attack Todoroki from above, when he felt a pain from two different parts of his body, from his face and his gut as he was being pushed against the side of a building by Mizuki and Izuku with Mizuki shouted that she was suddenly able to move.
"It's good you can move, Lil Sis" Izuku said while clenching his fist a bit.
'This guy would be easy to be dealt with if they weren't around though'
'So why don't you take him down?' Sukuna asked him with Izuku just chuckling inside.
'Let's just say I wanna see those three to have a fighting chance' Izuku finished.
Todoroki wondered if there was a time limit, and Native said that if that were it then Mizuki should be the last one to recover. Stain internally wondered if Mizuki's blood type was O, and elbowed the girl off him while avoiding a kick from Izuku.
Mizuki quickly distanced herself out of the way when Todoroki told her too. The wave of ice spikes drove Stain back again with Izuku jumping out of way and this allowed Mizuki to regroup with Todoroki.
Mizuki then rattled off three theories for how Stain's limit worked based off what she had seen so far. The last one was blood type, and Stain smiled and confirmed that was correct. He got an upclose quirk explanation right afterwards. Stain's quirk was called Bloodcurdle, and could stop people moving for a certain number of minutes based off of their blood type.
Both Mizuku and Izuku admitted that knowing his quirk didn't help much at this point. Todoroki said he'd hoped to carry the other two out of there if one of them recovered, but that Stain had proven too fast for that to be an option. The best they could do stall him and avoid close combat until some pros arrived.
Izuku landed near them which spooked them as he said that he can carry Native and Iida but right now it still undecided if he should since their's no telling what Stain has up his sleeve.
Mizuku couldn't help but agree and told her brother to stay and keep theri numbers up and then told Todoroki that he'd lost too much blood.
"I'll distract him while you support me from fither back" Mizuki said to Todoroki with Izuku grabbing his lil sister shoulder which got her to turn to him, "Come on, you can't forget about me?" Izuku said with Mizuki smiling.
"Then let's do this together, Big Bro"
"It's a big risk...but I'll do what I can" Todoroki said with Izuku smirking.
"The three of us will protect them!" Izuku said out loud with the sword that was tied at his back.
Todoroki's thoughts revealed that he had been worried about Iida too, ever since he heard about what happened to his brother. He knew what someone looked like when they were about to act on pent-up resentment, since he'd been through that himself. He also knew how those emotions could give someone tunnel vision. While he was thinking, both Izuku and Mizuki were starting to bounce off the walls and Todoroki was producing more ice.
Todoroki thought about the day he visited his mother and explained things to her. She had cried, and forgiven his long absence much more quickly than he'd anticipated.
Todoroki's mother had told him that him being able to move forward would be her own salvation. Todoroki thought that the old him could never have gotten past his resentment enough to pick his father's own agency for an internship. He had no plans to forgive Endeavor, but he wanted to see what his father did as the number two hero in person. Despite how terrible a person Endeavor was, he could admire the judgment and instincts of a man who held such a position for so long.
Todoroki once again thought about how Mizuki, a girl who didn't have to be involved had changed his whole mindset about his quirk with just a few words, and marveled at how it had been so simple yet he couldn't figure it out on his own.
Iida was shown as he thought about what Stain had said about saving Native, and how Mizuki, Izuku and Todoroki had declared they would save him in their own ways. Then he thought about his own threats against Stain, and how different they sounded.
Mizuki fell back against a wall after Stain slashed her leg. He was kept from striking again by Todoroki's flames, but he'd still gotten enough blood to paralyze the girl again which resulted in him getting kicked by Izuku who had pissed off look on his face.
"You fucking hurt my sister!!"
He said with anger as he used the sword to strike at Stain who parried out of the way and went to stab Izuku that caused a large cut accos his chest but Izuku didn't care and punched Stains face that pushed him back but he simply smirked as he had his blade close to his lips with his tongue out bit that only resulted in Izuku grabbed the blade in time and kicked Stain far from him with a panic look on his face.
'I don't know why...but I don't want that killer digest my blood' Izuku thought.
Iida tried telling them to stop again, and Todoroki angrily told him he'd have to stand up for that to happen and commanded him to "Look properly at what you want to be!" Iida remembered how he swore that the hero Ingenium would defeat Stain, and was able to move his fingers.
Meanwhile Sukuna was seen on his throne, watching everything through Izuku's eyes with mild interest, even though he likes fighting...this felt more of personal thing for the three teens and Sukuna could only sigh.
"...I want this to be over with...I already know the outcome...which is so fucking stale to me" Sukuna said.
Iida couldn't help but start to remember the time he first told his friends about his brother and how much he wanted to be like him and he began to wonder just what kind of hero he was, laying there being protected by his friends and putting his vengeance over saving Native. In that moment, Iida finally realized how narrow minded and selfish he'd been acting.
A flashback was seen and a younger Tenya talking to Tensei. Tensei asked if he wanted to be a hero, and Tenya emphatically, but stiffly, said yes. Tensei joked about his brother being a robot.
Tenya asked why Tensei continued being a hero. Tensei explained that it was partly because he had been expected to become one, since so many other family members were too. But it was also because he thought people who did things like lead lost children to the service counter were the coolest. Tenya asked why he didn't work at a service counter then, which annoyed Tensei.
Tensei patted Tenya's head and commented on how literally he takes things. He said that Tenya was smarter and more athletic than Tensei was at his age, which means that if Tenya admires him then Tensei just might be an amazing hero!
Iida remembered Stain calling him and his brother fakes. Iida decided that Stain was right, he couldn't hold a candle to his friends! But that didn't stop him from forcing his hand to move...
While that was happening, the still frozen Mizuki tried to help her brother and Todoroki by calling out where Stain was coming from. Stain was pushed back at first, but then started closing in again. He called out that Todoroki's focus on his own quirk was making him careless. He got in close, and the camera went slow motion as Stain's blade was shown to be mere inches from severing Todoroki's arm.
Izuku was seen a bit far away with widen eyes as he launched himself towards them.
In that same moment, Iida was finally able to push himself up. He told himself that if he didn't do something now, he'd never be on par with his friends or brother! That's what gave him the strength to use his recipro burst right off the bat. One kick knocked the blade away from Todoroki, and a second sent Stain himself flying away.
Stain didn't realise until it was too late that Izuku was there and sent the hero killer a devastating blow to the gut that caused him to get pushed back and hit the wall hard, making it difficult to get back up as he glared at Izuku who grabbed his little sister while also glaring at Stain.
Upon seeing that Iida was free, Todoroki commented that Stain's quirk wasn't as great as he thought.
Iida apologized to Mizuki and Todoroki, saying they shouldn't have gotten dragged into his mess. That's why he couldn't let them be hurt anymore! Stain said he shouldn't bother trying to look reformed now.
Stain declared that people don't change that quickly and Iida would always be a selfish fake!
Todoroki called Stain an 'anachronistic fundamentalist' and told Iida not to listen to a murderer's logic.
Iida said that Stain was right this time, he had no right to call himself a hero, but that didn't mean he was giving up! He wouldn't allow the name Ingenium to go down like that! Stain came at them again, but Todoroki's fire held him back which resulted in Izuku clashing with Stain, "You guys better have a plan while I keep this noseless bastard busy!"
Izuku said while Sukuna was sighing.
'Brat...I think this little charade might being getting out of hand'
'Not yet...their so close'
Izuku finished as he pushed Stain away.
Native spoke up then, saying that Stain was after himself and Iida so it would be better for Mizuki, Izuku and Todoroki to run.
Todoroki pointed out that Stain wouldn't give them a chance to run even if they tried. Plus, something changed just now, they'd clearly done something to fluster the hero killer.
Todoroki analyzed what he knew about Stain's quirk while Stain tried to get in close again but Izuku didn't let him as the young boy simply used the hero killers blade as pole and threw it at Stain, who avoided it but that little distraction was all it took for Izuku to send Stain a kick to the chin and then a kick to his side that caused him to piie out his own blood,
Todoroki meanwhile came to the conclusion that it wasn't very powerful on it's own. Given its limitations, it must be hard for him to deal with multiple opponents. Plus, now that he had a time limit, he was getting desperate.
Todoroki thought about how Stain had 'crazy tenacity'.
Iida tried to use his quirk, but found his engines weren't working after his big move earlier. A thought occurred to him, and he asked Todoroki to try using his quirk to cool his engines enough for them to work again. Stain took the moment of distraction to throw another blade at Todoroki, and Iida blocked it with his own arm, then got one in the other arm a moment later.
Todoroki wanted to help Iida, but Iida just told him to work on his engines. Meanwhile, Mizuki realized she could move again, and started to power up her quirk as she watched how her big brother was holding out on the Hero Killer and waited for the right moment.
Todoroki iced Iida's engine and threw fire at Stain at the same time with Izuku avoiding the flames but not before kicking Stain high Stain high up into the air.
Iida used his teeth to pull out the knife, and declared he'd throw away his arm in order to fight.
Iida called out 'Recipro extend!' and used his quirk to launch himself straight up into the air at Stain. At the same time, Mizuki got full cowl going and also launched herself at Stain.
Both Izuku and Todoroki grinned when they saw that both would reach Stain at the same time. Stain was taken off guard by the fast, simultaneous attacks and received a super-powered punch to the face as well as a recipro kick to his back.
Meanwhile in another part of the city 'minutes earlier' where Endeavor and Gran Torino were still fighting the Nomu that attacked the train.
Endeavor threw a fire attack at the Nomu, which caused it to back off a bit but not go down. Endeavor commented that no one had stayed conscious after he used that level of heat before, then the Nomu was suddenly throwing the fire back at them.
Edeavor noticed that, despite the absorb and release move, his own attack had still damaged the Nomu, so he declared the quirk being used weak. Torino quickly warned Endeavor that this thing would have more than one quirk. Endeavor said 'so that's how it is' and prepared to fend off the now charging Nomu.
Gran checked to make sure the civilians had left, then prepared to get back into the fight. Endeavor prepared to attack as the Nomu leaped at him, but Gran blasted up and bashed it into the ground before Endeavor could do so. Gran complained about breaking the street due to being rusty and Endeavor begrudgingly complimented his skill.
Gran said they should quickly deal with turning in the Nomu so they could go help with the main fight.
Endeavor remembered when he'd last seen his son. Todoroki was running after his father, but stopped when his phone buzzed. After seeing what it said, Todoroki started to run toward the address. Endeavor shouted for him to come back, but Todoroki kept going. He told Endeavor the address he was going to, and told him to come back with help once things were resolved. He didn't doubt his father would finish things quickly.
As Todoroki ran, he thought about how his friend may be in danger.
Back in the present, he said that his sidekicks would handle turning in the Nomu and told Gran Torino to go to the address Todoroki mentioned. Endeavor said he alone would be enough back up for the main fight.
Back at the Stain fight, both Iida, Mizuki and Stain were just starting to fall after that double attack. Mizuki felt a sudden pain in her limbs, and she hoped she hadn't broken them again.
Stain suddenly recovered enough from his shock to grab his sword and swing it at Iida, it barely missed. Iida declared he would defeat Stain the right way, with himself the hero and Stain the villain. Iida gave him another super-powered kick, which was followed immediately by Todoroki's fire. Todoroki then made a slide of ice to lessen the impact damage for his friends, though they ended up hitting their heads on the ice wall behind Todoroki anyway but that was only Iida since Izuku got Mizuki safely into his arms.
Iida moved to get up right away, but they all paused when they saw that Stain was laying limp and unmoving on one of the ice pillars.
Mizuki who was still in her bothers arms noted that he was hopefully knocked out. Todoroki started talking about restraining and disarming him.
Back at the main Nomu fight, the local pros were still struggling. They tried to attack all at once, but had to stop when the Nomu used its strength to make a shock wave. It used the limited visibility to sneak up on one of the pros, but before it could attack her it was punched across the square by Endeavor.
Endeavor and the Nomu went head to head. Endeavor noticed that the Nomu was regenerating after being hurt, so he created a concentrated and continuous blast of fire around its head. The fire went from red to blue by the time Endeavor stopped and the Nomu dropped to the ground. Endeavor smugly announced that carbonized cells can't regenerate.
A moment later, the winged Nomu flew off with someone in its claws. Endeavor immediately took charge of the situation, directing the heroes with quirks that weren't effective against the Nomu to go to the address Todoroki had run off to. Then he went after the Nomu himself.
Endeavor did some very impressive things with his quirk in his pursuit of the Nomu, including running up a wall and throwing his fire like he was Zues throwing a lightning bolt. He managed to make the Nomu drop the person it had picked up and caught him before he fell to the ground. He shouted that the Nomu wouldn't get away as it flew off.
The scene switched back to the alley, where Stain's weapons were laid out on the ground and the boys and girl were making sure Native had recovered from his paralysis. Native was seen getting up and thanking them, while Shoto and Iida made sure Stain was secure.
Iida volunteered to pull Stain along, but Todoroki rejected it. Iida's arms were injured after all. While they moved, Native apologized for being no help during the fight. Mizuki simply argued while being tired that it wouldn't have mattered due to how strong Stain was. Todoroki agreed, saying that with the four of them fighting and Stain messing up at times that it was still a close thing. Iida was quiet as Todoroki talked.
Suddenly something happened that caused Izuku to widen his eyes and shouted for Shoto to let Stian go quickly.
He didn't know why but he couldn't help but listen as he dropped Stain just in time as multiple blades were seen that cut away the restraints that Stain had on.
They couldn't help but feel...fear...they felt like their bodies were being pulled down to the ground, Iida saw his life flash before his eyes along with Native and Todoroki, Mizuki stated to sweat as she felt this aura that surrounded Stain who was choking on his own blood, with Izuku his eyes narrowed as sweat poured from his head...as he felt this familiar energy...the one that dwells inside of him.
Sukuna on the other hand...was livid...as he crushed one of the many skulls near him.
"Who did this.....WHO THE FUCK DESECRATED A PART OF ME!! I'LL KILL THEM!!"
Sukuna yelled out loud as Izuku heard it in his mind.
Meanwhile Stain suddenly stops choking and got up, his outfit, torn to shreds with only his upper body being bared as strange markings were seen, both his arms, twisted inhumane like as he leaned forward with his eyes completely bleed out and mouth hanged along with his tongue that reached straight to the ground, his hair moving on it's own as his voice was heard...crooked and strained.
"Cleanse...I will cleanse and purge"
As he said that, he disappeared from their view as was seen near Iida with a long katana that was ready to plunge at the young man.
But he was stopped by Blue like energy that pushed him away, Stain growled out in anger at the person who stopped him...as it was Izuku who stood in his way...but it wasn't him...Ryomen Sukuna was the one who was in control as Mizuki was seen staring st the back of her big brother...and yet she could tell it wasn't him as he looked at her direction with no sense of interest in his eyes.
"If you value your lives....you better leave"
That's all Sukuna said as he blitz towards Stain and sent him off as he followed after the deformed Hero Killer.
Mizuki shed tears as she couldn't do anything again for her big brother.
Meanwhile Sukuna's eyes narrowed with distaste, 'Whoever did this, won't live to see another day'
'Sukuna...what happened to Stain?'
'That thing is no longer human...because someone somehow give that thing....a part of me and modified it...and that pisses off!'
Sukuna screamed out as his inate domain shook inside of Izuku's subconscious.
