[Dagger]

It would seem that I am a moron, and I need some advice about how to get on Hisui's path without constantly dying. Major thanks to anyone who can help me get an ending with this lovely character.

Spoiler for my problem:

Okay, so I thought I was on the right track, because at one point I managed to get Hisui instead of Ciel in the Ciel-Sensei lesson. (She told me to trust her, so I went back and told Hisui what I'd be up to where you're given the choice to divulge it to her or lie). But it seems like no matter what I do earlier in the game, I end up getting the DMN (or whatever it's called, heh) ending. Argh!!
