Funk’s Justice Vs. Deku (My Hero Academia)

Hero training in Funk's Justice Vs. Deku (My Hero Academia) does not start in a city battle; it starts on a rhythm stage. Future Pro Heroes study at U.A. High, where teachers try to guide Quirk users so their powers protect people rather than harm them. Some students chase glory, others chase justice, and the line between hero and villain is not always clean in this anime world.

Into this comes Izuku Midoriya, better known as Deku, who was born without a Quirk. After inheriting power from the top pro hero known as All Might, he joins the academy and trains to stand among the strongest students. The mod throws Boyfriend straight into Deku's path, turning their clash into a full Friday Night Funkin music battle instead of a fistfight.

How to play?

Watch the colored arrows slide in from the side of the screen and press the matching keys in rhythm to keep Boyfriend's vocals on beat. Hit full combos during tougher sections to keep the health bar from tipping toward Deku's side. Miss too many notes and the track ends in a loss for Boyfriend, even if the song is almost finished.

Follow the opponent's pattern carefully, because Deku's parts often signal when the chart becomes denser and faster. React early when long streams of arrows appear so fingers stay ready before they reach the hit zone. Stay focused on the lane rather than the background animation of My Hero Academia characters, since every distraction makes drops more likely. Hold your timing as the song peaks and prove that Boyfriend can stand his ground against a U.A. hero candidate using rhythm instead of raw Quirk power.
