From the publisher's website:
Cel*style creates games for people who like anime and manga.
That's what Cel*Style is all about. Role playing games by indie designers from around the world, created specifically to capture the beauty, intensity and strangeness of manga and anime.
Live action anime in your hand: Each Cel*Style game allows you to explore a new world and create stories with your friends. Playing a Cel*Style game is a lot like a cross between being in a play, writing fanfic and drawing a manga. All you need is one of our game books and a few of your friends!
Anime games for you: Never played a role playing game? Intimidated by hit points, weapon skills and all that stuff? Don't worry! Cel*Style games cut away all that extra crap with easy to use rules to create the kind of stories that you like. You won’t need any "rpg experience" to play our games, just some imagination and a love of anime and manga!
