Kamiya was someone who had been through this himself, his strength multiplying several times over after forming a contract with Hannya.
Beyond Shikigami, there were other methods to enhance one's power in a relatively short time.
For example...
Kamiya started a new page in his notebook, writing down—
[Transcendent Firearms]
Firearms really are excellent because they are easy to master.
Isn't there a saying?
It takes years to train a competent archer, but only months to train a competent gunman.
Of course, the "competent" here doesn't refer to a marksman, but merely to a level barely sufficient.
"To raise Shouka, initially, we really had to scrape by, but that was unavoidable..."
Kamiya sighed.
In fact, it wasn't just archery; cold weapons are generally harder to master compared to firearms.
