I only played Sengoku Rance a long time ago and I enjoyed it. I don't think I got very far, though. I'm hoping to go through the series. I highly respect Alicesoft, but I honestly haven't played much of their titles. The only Alicesoft game I've finished is... Atlach=Nacha, which was very good.

As for the character, I think he's a funny guy with funny teeth... If you changed a few things about him, he'd definitely fit right into a shoujo manga (with Sill being the self-insert girl).
