Klaus Nietzsche

"How pitiful people are. They always yearn for what they don't have. They always reach out to what can't be reached. What does the Emperor of Eternal Darkness lack? That would be light. Kurama-san, you didn't dry up because of the sun. You were thirsty for the sun. As you shunned and hated it more than anyone else, you envied and yearned for it more than anyone else. To the sun we could never obtain... Not to live on the cold battlefield, but under a warm sun. To the undying light within their eyes. Hence, you dragged the people who had taken that light into your own night, into this land of eternal night. And when that light still wouldn't fade, you could only hate... and love."

- Klaus speaking with an unknown man named "Kurama".

Klaus (クラウス, Kurāusu), his full name unknown, is the supposed leader of L'Obscurité. He was, at one time, Yūkiro Himura's mentor in both the fields of education and combat, and is responsible for Himura's loss of his Shinigami powers. Klaus, like Himura, is aware of the nine Jinki Fragments, and also seeks to collect them.
