The ability in Magecraft is first-class, but is a waste in the physical ability aspect?

Can summon tens of thousands of Familiars, but defends the rear area alone?

Regarding this, I just want to say a few words.

"That's not a problem!”

This is the story of a youth who obtained a miracle, an extremely cherished miracle.

"As long as there are Familiars(companions), then I am invincible!”
