Turning this useless piece of shit Mc into an overpowered Canon is fun and all but the author should have at least made it take 100 years instead of a couple months. It's stupid to make him the strongest in the continent in half a year just to spend a week on a dumb revenge fantasy then...
Best part of this series is the artist taking care to give characters different outfits when they aren't in suit and tie. Who else dresses up their Noonas every chapter?
