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.
An assassin group that is under the order of Kritiker ("critic" in German), a secret organization that falls under the Japanese police force.
The main enemies in the series are another group of assassins called Schwarz ("Black" in German), all of whom have supernatural powers. Schwarz begrudgingly work as bodyguards for the Takatori family, and this is how they meet Weiß. Later in the series, Schwarz is seen assisting a mysterious group known as "Eszett" (the name of the German alphabetic character ß) in resurrecting their deceased leader. Weiß is to Kritiker what Schwarz is to Eszett.
I have eyes in the back of my head
and I can see where this is going
You've had the upper hand, one too many times
You've had the upper hand, just bring me down
Your silhouette stops me in my tracks, I need to catch my breath
Hello miss deceiver, I got lost in your eyes
This is a dream, I'm a believer Just let me close my eyes
The lights are constantly flickering,
as you reach your cold hand to grip my chest
There's gotta be a better way,
to pull me back towards the ground
