A game for the Nintendo DS sparked the Manga adaptation. While it isn't too well-known, it's seriously a good series and well worth the read.
While the manga and game have slight shonen-ai undertones, all-in-all it's just a basic adventure game, with mystery, murder, and a plot twist that's just....amazing. The manga is in it's final arc, and the game is being translated.
Yes, I'm a fan of the manga! One of my favourite josei manga actually! (and before anyone decides to argue about its demographic, since yeah, it really doesn't seem like a josei manga, it is running in Ichijinsha's Comic Zero Sum, which is a josei magazine... along with another fave of mine, +C: Sword and Cornett; as far as I'm concerned, the demographic of the magazine a manga is serialized in is the be-all-and-end-all of which demographic a manga belongs to).
But yeah, pretty awesome story and I love the characters!
i've read it... it's not my favorite. but the art is emotion_kirakira
but's it's not so bad... a little dragging, but not too dragging.
i'd say it's got its own target demographic.i'm just not a part of it.
