Niko is a member of the Litchi Hikari Club. He is highly respectful of the club leader Zera, and is willing to do anything for him.

Spoiler

He gave his right eye to be used for Litchi. After witnessing Jaibo and Zera's affair, he is captured and burned alongside Tamiya. He later kills Zera with a urinal after he is accused to be a traitor, before dying of his own critical burn injuries.
