Kapi is a new character introduced by the developers of the game. You can meet him in the mod of the same name. He is a male cat, wearing a multicolored hoodie and grey pants. It’s up to you to figure out what his main songs are.
The beginning of the mod tells us a little about the life of this character. The dialogue Kapi has with Boyfriend suggests to us that they were friends back then. His place is an arcade, where he prefers to spend time. When you meet him in battle, remember not to let the bar turn fully red. Otherwise, you lose the fight.
