Starlight Project presents: In pursuit of becoming the strongest, Hoshikawa Uika conceals her identity and enters the men's professional wrestling ring. Hiding her chest and clad in a competition wrestling brief, she fights under the alias "Hoshikawa Tsubasa," gaining fame among male wrestlers and female fans alike for her strength and striking appearance. However, the promotion's owner, obsessed solely with corporate profits, grows resentful of her pure pursuit of strength. Determined to crush her, he sends his prized wrestler, "Goliath," to defeat her—only to see Goliath lose in their first match. As Uika declares on stage, "You weren't my enemy," the owner resorts to administering illegal performance-enhancing drugs to Goliath and forces a rematch. Two weeks later, the rematch begins. Confident at first, Uika is soon overwhelmed by Goliath's inhuman speed and power—far beyond his previous abilities. The cloth binding her chest is torn away, exposing her body as she endures relentless punishment. During the fight, Goliath notices her slender frame, smooth skin, and the soft swell of her breasts now revealed, finally realizing she is a woman. Filled with contempt, he begins targeting her chest with brutal strikes and viciously attacks her groin, mocking her lack of male anatomy. Uika writhes in agony, her wrestling brief straining and tearing under the assault, until she collapses, defeated, onto the mat. The owner then appears before her, declaring a woman's presence in the sacred ring a "guilty" act, and vowing to make her painfully aware of her weakness as a female. Thus begins a descent into hellish torment...
