Kenichi Yoshii (吉井 健一 Yoshii Ken'ichi?) was a member of the CCC in which he acted under the codename 09 (Zero Nine (ゼロキュー Zero Kyū?)). Unlike Zero Seven, he worked in the background developing technologies they could use in the field.

During Plan B (The Ikebukuro Incident), he learned that there was an inside plan to have Nanako eliminated, so he left the CCC with her in order to protect her.

Appearance Edit

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

After the timeskip, he seems to have developed a more mature face, along with a taller and slightly more muscular build; to the point where he is now taller than Nanako, the latter being 168 cm. He also grew his hair out to about shoulder-length and his bangs grew longer as well, framing his face more than before.

Personality Edit

Relationships Edit

Nanako Tenjo Edit

Kenichi 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. However, he later decided to put his unhealthy habit of taking pictures of her behind, and become her real friend and to always be by her side.

Trivia Edit

  • He is the youngest member of the CCC, initially being only 16 years old.
  • Kenichi developed the thermography scope Zero Seven used, as well as a GPS tracking system used to track CCC members.
