Summoner of Miracles

The magic talent is top-notch, but the physical ability is useless? You can summon tens of thousands of familiars, but you have to guard the rear alone? I just want to say one thing about this. "That's nothing!" This is the story of a boy who received a miracle and cherished it. "As long as I have my familiar companion, I am invincible!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
