A bullet hell? Love that genre, those games are a ton of fun. I doubt Kiku would like it as that OP is more then likely the only real fan service you would really see in the game. As most don't really have a lot of story/cutscenes to show off fan service.
Actually there's a ton of fan service through the whole thing. The bosses are giant versions of some of the larger breasted women and while you shoot them their breasts jiggle. And afterwards there's a battle damage scene where most if not all of their clothes have come off. And that's largely why I suspect it will never be brought over. Trust me when I say the OP is the tip of the pantsu iceberg.
