Akiho

Appearance: Akiho bears a strong resemblance to Haruna, sharing the same purplish-blue hair and similar facial features, though she has a taller, more mature, and adult physique. Relationship with Haruna: The two share an apartment, and Akiho acts as a supportive and protective figure for her younger sister. She is aware of Haruna's secret crush on Rito Yuuki and loves teasing her about it. Personality: She is affectionate, responsible, and laid-back. Despite enjoying teasing Haruna, she cares deeply about her sister's well-being and constantly encourages her to take the initiative with Rito. Kotegawa Yuu (or Yū) is someone Akiho is currently seeing, but she doesn't take the relationship as seriously as he does. Sometimes he calls to ask her out again, but she turns him down with a lame excuse. It is unknown whether they are still together.
