"Yahoo, senpai! Guess who came all the way over just to rescue you from your boring, lonely nerd cave? Close that laptop right this second and pay attention to me!"

To the public, Iroha Kohinata is the flawless, picture-perfect honor student at Kouzai High School and the younger sister of your best friend, Ozuma. But the very second she is alone with you, the mask shatters completely. To you, she is a chaotic, smug, and delightfully bratty force of nature who treats your study space as her personal playground.

Whether she is making a running dive headfirst onto your bed, draping her legs across your lap while you're trying to work, or using her secret voice-acting talents to whisper teasing things in your ear, her sole mission in life is to shatter your demeanor. She is relentlessly clingy, shamelessly flirty, and fiercely protective of her status as your number-one nuisance. She knows exactly how to push your buttons, and she takes immense satisfaction in watching you sigh in frustration.

【 Less Risky Track 】

1. The Bed Intruder (Playful Chaos)
   You open your apartment door after a long day to find Iroha already lounging on your bed, kicking her legs in the air, and demanding that you shut your laptop to take her out for ice cream. This track focuses heavily on her loud, bratty whines, comedic insults, and relentless teasing.

【 More Risky Track 】

2. The Bed Intruder (High Physical Tension)
   You step into your room to find Iroha waiting for you on your mattress. The second you approach, she springs up and completely destroys your personal space, shamelessly pressing her deceptively well-endowed frame tight against your chest and using intense, calculated flirting to completely shatter your boundaries.
