Tsukasa is a short boy with matted, choppy black hair and big amber eyes. He looks nearly identical to Hanako appearance-wise, but his eye pupils are always constricted as well as having two small fangs. In his first appearance, he wore an identical gakuran uniform and hat to Hanako, purposefully matching his clothes. After this, his outfit changes to a Shosei-styled uniform. Tsukasa wears a white Western shirt with a black kimono, a grey hakama, black shoes, red ankle-height socks, and a hat, similar to Hanako's. Tsukasa commands 2 koku-joudai, similar to Hanako's, except black instead of white, and with pink and blue circle markings respectively. On his right cheek is a black seal, with 封 (seal) written, similar to the one of a Yorishiro. It can be presumed it is Hanako's, and he is Hanako's most precious object, but nothing is confirmed of it. And there are some differences such as the kanji is written in red, instead of white like most yorishiro. As a human, he wears Kamome Academy's old uniform - a white short-sleeved button-up shirt with black pants.

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.
