Ron discovers that he has transmigrated into the body of a man in another world who is useless at both magic squares and battle aura. Facing a disastrous situation from the start, he has no choice but to survive by working as a laborer, helping mercenaries carry their spoils. But then a green flame suddenly flies out of the body of a dead spiked-armored beast and enters Ron...
“You’re useless at both magic squares and battle aura, so how can you do that?” That’s what people say about Ron.
Ron says, “I can’t use battle aura or magic. I just absorb a little soul energy and summon a few things, that’s all.”
