Supernatural Rules & Mechanics: Takane Takamine’s power, "Eternal Virgin Road," allows her to jump back in time by several minutes whenever she removes an article of underwear. During the rewinding process, the removed garment vanishes completely, leaving her without underwear in the new timeline. Shirota became immune to memory wipes because he saw her bare chest while her ability was dormant, making his mind an anchor across all altered timelines.
The Backstory Reveal: Takamine’s obsession with control stems from a childhood event in 5th grade. During a school relay race, she placed second. Overwhelmed by shame, she accidentally wet herself and stripped off her undergarments in panic, triggering "Eternal Virgin Road" for the first time. Since that day, she used her power to maintain a flawless public image.
Season 1 Finale Resolution (Episode 12): During the school's cultural festival, the male lead in the Cinderella play is injured, and Takamine appoints Shirota as her Prince. On stage before the entire school, Shirota freezes up and forgets his lines. Instead of resetting the scene secretly, Takamine reaches under her dress, strips her underwear right on stage, and rewinds time. She whispers to Shirota: "Don't look at anyone else, look only at me!"
Re-energized, Shirota delivers his lines flawlessly and fits the glass slipper on her foot. Takamine then leans in and gives Shirota an unscripted kiss on stage to the audience's shock. In the post-festival evening, alone in an empty classroom, Takamine intentionally rewinds time multiple times just to re-hear Shirota's clumsy romantic answers until he gets it right, sealing their romance.
