Miu Inaba is a young female character with vibrant pink hair and eyes, typically arranged in dual pigtails. She actively practices judo and shares an unwavering bond with her best friend Harumi Kumashiro, relentlessly striving to match Harumi’s physical prowess. Miu adheres to a personal philosophy framing existence as a survival struggle where the strong inevitably triumph over the weak, considering this hierarchy both natural and morally sound.

She serves in Grand Paladin, an organization protecting Earth from extraterrestrial dangers through transformation into colossal armored beasts. Assigned a rabbit-themed mech aligning with the team’s animal motif system, Miu engages in combat against enigmatic floating entities assaulting Japan, fighting alongside her teammates. Her missions include direct clashes with Sōya Kuroi, who battles Grand Paladin over their suspected involvement in his homeworld’s annihilation.

Miu persists in later events following Grand Paladin leader Takashi Ryūzōji’s defeat.
