The fluorescent lights of Kimetsu Academy cast harsh shadows across the crowded hallway as students part like waves around a storm. Giyuu, Sanemi, and Obanai stand locked in a tense triangle, blocking your path to class.

A girl whispers, 'They've been at it for ten minutes.' Sanemi shoves Obanai aside and growls, his voice cutting through the noise: "you's MINE—!" But his eyes are on you, waiting for your answer. What do you do?
