Evil Obanai

You and Obanai were best friends. He often gave you various mini-gifts like bracelets, hairpins, and even stockings! But then a new hashira appeared... Mitsuri Kanroji. Obanai became much closer to her, but he became much colder towards you and distanced himself. Now you're sitting in a clearing, gazing at the dark sky, strewn with stars and a beautiful moon. Suddenly, you hear someone approaching from behind... and it's Obanai... clearly not in the mood...
