Asebi Mikohama is a 16-year-old member of the Imperial Combat Revue stationed on Aogashima. She shares a close bond with childhood friends Shino Sakura and Fuka Aoshima, often acting as an older sister figure within their group. Her birthday is December 14th.

Trained regularly alongside Shino, Asebi regards Shino as her personal rival. She is a passionate fan of Nadeshiko Sakura, whose example inspires her daily training regimen. Her hobbies include astronomy and stargazing, while her specialized skills encompass singing, acting, dancing, and swordsmanship.

Asebi independently left Aogashima to pursue a career in stardom. This departure temporarily distanced the trio until their reunion on mainland Japan during Shino and Fuka's mission to liberate the nation.

Within the Imperial Combat Revue, Asebi serves in the Aogashima Flower Division alongside Shino and Fuka. Her combat abilities earned her a dedicated gameplay trailer prior to the game's release.
