Synopsis:

After being kidnapped by an insane C-class hero,
Hornden awakened his abilities.

“What ability is it?”
“It’s an amplification capability.”
“No, so I’m asking what am I amplifying?”
“It is the ability to amplify the power of other heroes.”

Is that a useful ability?

“S grade… … .”

The researcher said calmly.

“To manifest the ability, you need to make contact with the competent person.”
