Alexei Bergenikov (アレクセイ・ベルジェンニコフ), more commonly known as Danjou (ダンジョウ), was the leader of the Danjou Boxing Club.
Danjou was a large man with pale blue eyes and short blonde hair that's shaved on the sides. He was usually shown wearing a white sleeveless keikogi and a dark belt.
Danjou was an upright and honorable man. Not liking the Darwin's Game's system of killing, he used his special privilege he earned from an event to set up a martial arts battle system that the clan could use instead of actually killing people. He was also strict, expelling Inukai for challenging Sudou Kaname without permission. Despite being Russian, he refered to himself as Danjou because he liked Japan.
