Four guys work at a florist and seem to be normal folks. Truth is they all work for an underground organisation, "Weiss Kreuz" (white cross), and together they are a group of assassins who bring justice to society by eliminating those the Government cannot reach. All four, Aya, Youji, Ken and Omi have their own dark secrets and pasts which lead them to this occupation, and by no means is it a glorious one either.

As they carrying on their tasks, they encounter the seemingly invincible group, "Schwartz", who possess telekinetic (and other) powers as they block their way.

Weiss Kreuz is a well structured series with different stories with an underlying secret yet to be revealed.

Weiss Kreuz Gluhen introduces two more characters to Weiss, namely Kyo and Sena. In this series the art has been advanced to a DVD like quality, and focuses on a more central and solid plot, exploring the role of the "Estet" and their experiments.

A spy/ action thriller, Weiss Kreuz or Weiss Kreuz Gluhen offers the anticipation of any mystery subplot, waiting for viewers to unravel.
Synopsis by: Kuroimisa

You have to give it to the Koyasu, despite not being the greatest anime of all times it is a classic and the plot is a good one, but it would definitely take more than the 24 episodes, two ovas and second part of the series shown to wrap this one up. Too many doors are opened and not enough are closed behind. However, in spite of every single down point that goes to it the creativity behind it is nice enough. Although the four main characters fall into cliché because of their personalities together they make a good group which faces dramatic issues and sentimental problems well enough.

It could me much more unrealistic but all-together with the music, the voices and the plot make it work, perhaps if they were separate they wouldn’t be good but altogether they work.
