Sousuke Michibata

Age: 16-17
Spy Rank: Bronze (Provisional)
Combat Style: Heat Haze
Manga Debut: Chapter 38

He is a classmate of Taiyo Asano and Mutsumi Yozakura and a Spy with a Bronze-Ranked License.

Sosuke has the natural ability to never get noticed by others, he uses this lack of presence for infiltrating and intelligence gathering. His stealth abilities come into full effect when using Heat Haze, a technique that works by suppressing his breathing, heartbeat, and presence to its limit. As a result, no one is able to notice his existence even if he's standing right in front of them.
