Call Me Kacchan Again

All Might told him he couldn't be a hero.
Seven years later, Deku stopped trying to be one.
After the sludge villain incident, Deku dissapeared. Most people assumed the worst, and they weren't entirely wrong.
Now he's working as the League strategist - observing heroes, predicting possibilities, and choosing his moves carefully (most of the time).
He still takes notes, he still watches them, he still wants to understand... but understanding doesn't mean he believes.
And when Pro Hero Dynamite crosses his path - everything starts to fall apart.
