Oh, you could play "Kumon-mi Teacher: Wakana", with Sensei but they wouldn't really play off eachother. The idea was that Wakana and Osako would work more as Union cards, like Osako's attack being one of the highest in the deck (even if attacking wouldn't be the main point of the deck), and Wakana maybe being able to attack directly, and if equipped to Osako, allowing her to attack directly instead. Lesbian combo attack.
Imani would probably just be a quick play spell card or something, tbh. Maybe a continuous spell that allows the player to draw an extra card per turn if Sensei or Wakana is on the field. I was thinking she could do "burn" damage but that became a little tasteless the more I thought about it.
Overall, the main ideas were that Ami and Maya are the decks searches, Sensei would be a card you'd always want out, and spell cards being the decks main strength. Happy events causing the opponent to skip a turn, Lust events increasing your life points, and the main field spell making it so that you don't take battle damage from attacks involving Kumon-mi monsters, and they return to the deck (or maybe hand) if destroyed. Outlasting the opponent would be the goal.
