Part 1 of 3
Summery: In this crossover fight between Imai Cosmo and Mikumo Kushinada, all energy-based powers—including Ki, soul power, and any form of ability manipulation other than physical prowess and combat techniques—are nullified. Mikumo Kushinada, a powerful and legendary woman, learns of these magical restrictions only as the fight begins; disoriented and arrogant—accustomed to viewing others as inferiors—she immediately loses control of the match. She is unable to employ her signature techniques, such as energy manipulation, defensive auras or barriers, long-range attacks, giant soul-form expansion, or perfect body duplication. Within three seconds, she sees her opponent—the young, athletic Imai Cosmo, an expert in close-quarters combat and submission holds—sliding across the ground and launching a powerful kick toward her face. Mikumo fails to stop the blow and takes the kick to the face; Imai drops to the ground, spinning to launch a follow-up attack: his left hand grabs her clothing while his right fist drives toward her face. Despite being disoriented and having many of her techniques sealed, Mikumo remains a formidable close-combat fighter; she uses her massive breasts like a vice, executing a powerful spin that traps the boy's arm—creating a provocative move—and employs a judo-style spinning throw, using her bust to disorient Imai Cosmo before slamming him to the ground with great impact.
