Mitsuzane Kureshima

Mitsuzane Kureshima (呉島 光実) is Kamen Rider Ryugen (仮面ライダー龍玄). He is a member of Team Gaim and Kota sees him as his younger brother. Though he kept this as a secret, in reality, he is the son of the leader of the Yggdrasil Corporation and attends an elite high school. He wants to live freely and won't accept the path established for him. He uses the Budou Lockseed and has a Chinese Armor motif.

Arms
Like with the other Lockseed-using Kamen Riders, Kamen Rider Ryugen's forms are called Arms (アームズ).
