I'm trying to remember this anime I watched a lot as a kid, when I was about 9-10 (1999-2000). I believe it was on Cartoon Network - maybe on Toonami? The details are hazy, but I'll share what I remember in hopes of rediscovering it: It was about this guy and a group of girls, and I think they lived at a bath house or something? They were all gaga over him, but he wasn't really interested. This went on for a while, until in a later season, I think, (or a spin-off series?) he moved away and fell in love with this young woman. But it turns out she's nothing but a "shadow" created by this evil magical little girl. I don't remember much other than that, except that the girl he was with would fade in and out of photographs.
