Personality
Akiho is very mature, though in an adult-like way, and she is a casual dater. She enjoys dating boys, but has no desire for a serious relationship, and only intends to "play with them for a while".

She is extremely popular with the guys (having received confessions from two men at the same time), but continuously turns them down, as her sister states she is not looking for love at the moment. She has been dating Yuu Kotegawa, though she isn't taking the relationship seriously.

Haruna Sairenji
Her little sister who she  occasionally would  enjoys teasing over certain things  like having friends over, which Haruna greatly dislikes, although they do get along closely. She suspects that Haruna and Rito have romantic feelings for each other, and is "gleefully" supportive of them.

Yuu Kotegawa
Yuu  is someone  Akiho  is currently dating, but she isn't taking it as seriously as he does. Sometimes he would call to ask her out again, but she would decline with a dishonest excuse.

Maron
−		 −	Maron is basicly her pet dog but since she is often at work, her sister Haruna is always the one taking care of him.
