Ore wa Otoko Da! Kunio-kun

Overview

In a school of delinquents, there's one student that hates guys who pick on the weak, and his name is Kunio. He's as strong as they come, but unfortunately he's also lazy and perverted. Can Kunio win all of his challenges and survive the crazy antics of his opponents? Ore wa Otoko da! Kunio-kun is based off the Kunio-kun videogame series, which includes the game that was localised in North America as River City Ransom.
