Kurumi Azuchimomoyama, a 14-year-old student at Egaogaoka Middle School, transitions from ordinary adolescence to the magical girl dinosaur angel warrior Prima Pink after encountering Devilun, a Tasmanian devil-like angel. Tasked by Devilun to oppose the Darkness Whales organization, she wields weapons emitting a metallic, blood-like scent, unleashing them ruthlessly against foes. Her appearance features light skin, long blonde twin ponytails, and pale blue eyes, with her Prima Pink persona clad in a pink skirted costume, white gloves, and high heels.

Kurumi’s personality merges contradictions: she claims shyness yet boldly proclaims her actions, balances a cheerful, sugary disposition with self-professed clumsiness and tearful tendencies, and upholds a fierce commitment to justice. This idealism, however, twists into moral ambiguity. Easily swayed by directives labeling others as threats, she employs disproportionate violence, including lethal measures, to fulfill her mission. Fear of solitude as the sole Prima Angel drives her to manipulate peers like Mizuki into unwillingly joining her crusade, revealing self-serving motives beneath her heroic guise.

Her story unfolds comically, observed by three uninvolved male classmates who critique her exploits. While her background remains unexplored in supplementary media, later narrative expansions introduce additional Prima Angels, hinting at her evolving role in the battle against the Darkness Whales within the series’ episodic framework.
