 * This article contains major plot spoilers from the manga that have not been revealed in the anime. Proceed at your own risk.

Kenichi Yoshii (吉井 健一) was a member of the CCC with the code name 09 (Zero Nine (ゼロキュー)). Unlike Nanako Tenjo (Zero Seven), he worked in the background developing technologies they could use in the field. Most notably, he developed the thermography scope Zero Seven uses as well as a GPS tracking system used to track CCC members.

He has a genuine crush on Zero Seven, but he initially didn't have the courage to straightforwardly approach her and would often secretly take pictures of her sleeping and collect them.

During Mission B (The Ikebukuro Incident), he learns that there is an inside plan to have Zero Seven eliminated, so he leaves the CCC with her in order to protect her. He also decides to put his unhealthy habit of taking pictures of her behind, and become her real friend and ally, as well as face her straight on.

Kenichi is a teenager who is below average build and height for his age. He has short ear-length, sage green hair which is styled into a style that resembles a bowl cut. His bangs cover his forehead and frame his face. He wears rectangular glasses which he wears over his light-green colored eyes.
