Hello!

I read this manga a long time ago and forgot the name. I believe it was a one-shot or short story, it had a dark, gothic mood. It had to do with a guy who was obsessed with his sister, I think he kept her locked up, but in the end it was revealed that it was only because she had the same face as him - in fact, he was obsessed with himself. I think there was something about a dress and BUCK-TICK (the band) inspired this story somehow?

By the way, I would like recommendations on manga that are inspired by real-life bands/singers/artists. Not like AKB49 - Renai Kinshi Jourei, where the group members are actual characters, but more like the story is inspired by a song or something like that. I have read manga like that before and it is nice to discover new bands that way.

Any help is appreciated!

For the 2nd request:
Sukima Shiki >> the stories inspired by Sukima Switch's songs.
Moteki >> the chapter titles taken from songs.

First one is possibly Die.

Yes, it was Die, thank you Reiz0r!
I had already read Sukima Shiki, and for the second request I would like the music to influence the story, not only the chapter titles, but I will try and check out the songs. Thank you p3pelepe
