Oota Ane

Oota Ane is the older sister of the story's protagonist, Oota-kun — an upbeat and high-energy college student whose over-the-top enthusiasm has earned her the nickname 'Crazy Oota' among her peers. She takes great delight in teasing her expressive younger brother and frequently meddles in his interactions with Kashida just to stir things up. Beneath her mischievous exterior, however, she operates as a self-appointed 'love strategist,' quietly working to bring the two closer together. She is, at heart, a family member who may cause trouble on the surface but genuinely cares about her brother's romantic life.
