Insane? You need a fast clear to get plat, for first phase you need to use Eimi yes or yes, build her, also use Hifumi + Fubuki strat, they dont need too much investment.
For 2nd phase use Utaha, normal Neru, borrow the DPS and use all the buffers you can or a healer like Kokona/Serina if you dont have Ako

Torment? Impossible
