Masaki, Kyosuke

He originally founded Midnight Angels with ten friends and became its first legendary leader. The gang grew and recruited new members. He was succeeded by Akutsu Junya, who became the second generation leader. He is the Oni-Baku's idol, sharing with them his vision of Midnight Angels. He believes that Midnight Angels is not some cheap bike gang but they are Shonan's free roadsters.

[Spoiler] Sometime after, he lost his life at a sharp turn on the old Odawara Highway due to an oil slick on the road, going further than anyone could ever reach and became a legend. [/Spoiler]

His face is never shown.
