Looks like a host band. Not sure if they would qualify as a visual kei band or not. Here's the Japanese Wikipedia article. https://ja.wikipedia.org/wiki/AcQuA-E.P.

You’re right that they’re a host band and don’t really “feel” visual, but I remember them heavily marketing to VK stores when they debuted, so I guess it’s worth including them.

Their support members were apparently famous as well.
