Hoshi, Kouichi

星光一

Kouichi is Shinichi's older brother and works as a secret agent for an organization named Phoenix, operating under the cover of a manga artist. His main adversary is Interspy, although he also battles other foes.
Kouichi occasionally uses firearms, but he mainly depends on martial arts and his watch, which houses a small hammer and chain, a radar, and a flashlight that can also function as a blinding beam against opponents. His pipe holds smoke gas capable of hiding his location. Within Phoenix, he is identified as Agent P77. Kouichi joined Phoenix to avenge the death of a friend (who had formerly been Agent P77) that was killed by Interspy.
