Reaper.@ Though, it's no really matter what we think or like the chose is for Kamito to made.
Also for the harem ending we need that Kamito like all the girls in romantic way,thing that until now don't happen. Though he do say that the girls are cute or thing like this and praise them(Ellis ecc) though the only one that praise and say the praise to her was Ellis. to the other was more him think(I think). It's more possible that end with Kamito + the 2 spirit sword or one of them.Then again we do know who he want the most. Yet we know as well what Restia and claire sister try to do .
