Man Insane was horribly easy so torment will probably be mandatory but I don't have time to do torment today or tommorow.

I think the torment team I can most easily replicate is one that looks popular with iMari, dAru, Kot, sHanako, Kisaki and Rio.
My iMari is underinvested and I don't have the ligma to get her up, so I was planning on borrowing her since I have the rest of the team, but a lot of the clears have a 5* Rio and Kot, anyone know if those are needed or are they fine at 3*?
