Nanamine Sakura is a 3rd-year student at Kamome Academy's High School division. She made a contract with Tsukasa and is now bound to him. She is a member of the school's Broadcasting Club. Sakura has green hair styled in an asymmetrical bob cut with very short bangs. She has two pieces of hair left in front of her ears to frame her face, and two more long sections that extend to her chest. She also has two braids that extend from the crown of her head down to her ears. Her eyes are green with yellow flecks. She has notable eyelashes and always has her eyes half-closed, giving her a somewhat drowsy or disinterested look. She wears the school uniform with a red gem brooch above the front bow. Unlike Nene's uniform, Sakura's is long-sleeved. She wears yellow stockings with brown stripes and garters. In the anime, her socks are brown and lack garters. Sakura is noted to be quite beautiful, and Nene calls her pretty when they first meet. Sakura appears to be taller than Nene. Interestingly, both of girls share aesthetic similarities, like their short bangs, brooches, and irregular stockings. Sakura seems to be an aloof person, and as such does not show much emotion. She rarely changes expressions from her usual deadpan appearance, although she does break this trend in order to smile during her first meeting with Nene and when she becomes annoyed with Natsuhiko and Tsukasa. For the most part she seems to deal with her involvement in the supernatural by simply detaching her emotions from it, for example thinking of Tsukasa as little more than a cat. She finds many of Tsukasa's actions distasteful, but has to listen to them regardless. She enjoys Yashiro Nene's company and treats her with hospitality and kindness, but is also willing to double cross her at Tsukasa's behest, indicating she may not be terribly honest. While she may legitimately desire Nene's friendship, she also seems to keep herself distant in order to carry out Tsukasa's requests.

Toilet-bound Hanako-kun
The famous "Seven Wonders" that every school seems to have are a staple of Japanese urban legends. One of the most well-known of these tales is that of Hanako-san: the ghost of a young girl who haunts the school's bathrooms. Kamome Academy has its own version of Hanako-san's legend. Rumors claim that if one successfully manages to summon Hanako-san, she will grant her summoner any wish. Lured by the gossip, many people have tried to call upon her, yet every attempt has failed. However, when Nene Yashiro, a girl hoping for romantic fortune, dares to summon Hanako-san, she discovers that the rumored "girl" is actually a boy! After a series of unfortunate events involving Nene's romantic desires, she is unwillingly entangled in the world of the supernatural, becoming Hanako-kun's assistant. Soon, she finds out about Hanako-kun's lesser-known duty: maintaining the fragile balance between mortals and apparitions.
