Kiitarou thinks he's cursed when a perverted yokai forces him into every ecchi scenario imaginable, except the joke is that he's genuinely miserable about it. Most harem comedies sell you on the fantasy of drowning in women; this one sells you on a kid actively fighting for his life. It's a bonus episode that exists purely to roast the genre it lives in, which means you either get it immediately or wonder why anyone bothered.
Kiitarou thought his days of supernatural trouble were behind him, but an encounter with Lucky Eros, a mischievous deity of fortune, turns his world upside down. The problem: this god's idea of luck involves throwing him directly into every embarrassing situation imaginable, courtesy of the female youkai constantly appearing around him. What should feel fortunate becomes a nightmare. Every coincidence is engineered chaos. Every accidental encounter becomes progressively more compromising. Kiitarou desperately tries to maintain his dignity and distance, but Lucky Eros has other plans, determined to "help" by manufacturing moments that leave him flustered and mortified. The special balances absurdist comedy with supernatural hijinks as Kiitarou scrambles to outsmart a literal force of fate. His panic is palpable, his protests ignored, and his luck decidedly not in his favor. If you appreciate comedy rooted in a protagonist's genuine distress and the chaotic interference of meddling supernatural forces, this bonus episode delivers exactly what you'd expect from a show willing to turn the tables on its main character one last time.
