Weiß Kreuz
Weiß Kreuz (Japanese: ヴァイスクロイツ, Hepburn: Vaisu Kuroitsu, literally German for "White Cross", accurately "weißes Kreuz" in German) is a series about four assassins that work in a flower shop called "Kitty in the House", a reference to their feline codenames. The assassins are members of a group called Weiß (white), which is run by Persia of the mysterious Kritiker organization.
The Weiß Kreuz franchise includes two seasons of anime and one OVA series, a light novel, two manga series, and several drama CDs. The four voice actors of the main characters - Takehito Koyasu, Hiro Yūki, Shin-ichiro Miki, Tomokazu Seki - formed a band named "Weiß"; several CDs and singles were released. Media Blasters released the anime in the North America as Knight Hunters: Weiß Kreuz.
