Premise (example) In a port city ringed by rusting industry, a once-bright meteorite—dubbed the Kegareboshi—crashes into the harbor. Those who come into contact with its fragments gain uncanny abilities but suffer creeping moral degeneration: small lies multiply into betrayals, kindness curdles to cruelty, and the city’s institutions begin to collapse. The story follows three protagonists—a municipal cleaner, a schoolteacher, and a rookie journalist—whose lives intersect as they uncover the meteorite’s origin and confront what it asks of them: sacrifice purity for power, or resist and face ruin.
To understand the animation, one must first understand the word. Kegare is a Shinto concept referring to spiritual impurity or defilement—often temporary, but powerful. It is not "sin" in the Western sense, but rather a state of disorder, pollution, or corruption that separates something from the sacred. A Kegareboshi is a "defiled star" or "fallen star."
This confrontation backfires entirely. Instead of burying the story, Ibuki falls directly into a trap set by , a highly manipulative, ruthless media producer. Trapped, drugged, and blackmailed, Ibuki and Koharu are pulled away from the safe confines of the stage and pushed deep into an escalating web of extreme exploitation, where their bodies and careers become collateral under Kurozuka’s absolute control.

From this point, the OVA abandons the idol aesthetic entirely. The bright lights of the stage are replaced by the dim, grimy interiors of hotel rooms and production offices. The story transforms into a psychological prison drama as Kurozuka systematically breaks down Ibuki’s will, turning her into his personal "sex slave," as multiple synopses describe it. While Ibuki is tortured, the theme of "NTR" (Netorare) is heavily implied as the relationship between the innocent Koharu and the slimy manager is exploited.

However, Akira starts to question whether the cost of maintaining Kyoshi's purity is too high.

Hideaki Anno’s Neon Genesis Evangelion is arguably the prototype for all Kegareboshi works. The "stars" here are the Evangelion units—godlike biological machines—and the children who pilot them. Rei Ayanami, a clone with a celestial name ("Ayanami" evokes wave patterns, while Rei suggests "zero" or "spirit"), is the quintessential Kegareboshi: artificial, fragile, and repeatedly broken. The show’s finale, The End of Evangelion , literally turns an angel into a defiled, bleeding giant crucified in the sky. Share public link Premise (example) In a port
