Well, Rigr was the cause as to why the Hiragi family fought or disregarded the Ichinose family; at the same time I don't think Guren will follow up Rigr's strategies anymore since he has his own agenda.

Guren in fact is a caring being, he's kind just like Yu was in the past but in order to reach out the promised dream, he has to sacrifice in order to reach it even so...that will have a mayor price for it.

I think Mahiru no Yo is just acting up; I mean, she's not a total demon, she keeps that malicious attempt and she doesn't care about stuff around her mainly because Guren is with her, but still she does care about Guren's feelings
