Yako/Relationships

Background
Yako is a supernatural haunting the Kamome Academy. Initially, she was an inari statue at a temple gate coming to life. It is assumed the temple is near Misaki's schoolhouse, as he went to pray every day for his students' well-being. Yako was known to his students as a girl's ghost who haunted the temple and frequently scared them.

After an encounter, Yako started studying under Misaki. At first, she recounted in her workbook that she found more joy in continuing causing trouble with other students. But her teacher was patient and took care of her, continuing to correct her behavior and her grammar. Yako slowly grew fond of him as time passed, developing a crush on him. Misaki later gifted Yako the hair shears he used, something that she treasured and kept safe in the shrine. After Misaki passed after an accident at the staircase, Yako heard of the news but didn't understand the concept of death, and stayed waiting for him to return.

As time passed, she finally understood and closed her heart to others, believing that Misaki was the only good human. When she becomes the School Mystery Number 2, it is inferred the School Mystery was named after the late teacher.

Hanako
Hanako as the School Mystery Number 7 has total control over Yako as the leader of the Seven Mysteries. Although, Yako makes little attempt to listen to his requests, only agreeing to help after Hanako threatens to make her into kitsune udon time and time again.

Yashiro Nene
Yako and Nene was not shown to have interacted much, but Nene was shown to be apologetic towards Yako for destroying her Yorishiro, and calling her Fox-san and tried to pet her, in which Yako bit her on her and instead, saying that she have absolutely no intentions to befriend Nene. After the incidents at her Boundary, Nene began to spread the rumors to describe the second mystery as a lovely one, instead of a deadly mystery.

Minamoto Kou
While Yako was initially hostile towards him, the two seem to have grown closer after she finds out that Kou had lost a friend due to the alteration of rumors. Yako ordered him to call her "Nee-san".

Tsuchigomori
Tsuchigomori and Yako have been shown bickering ever since his introduction as supernatural. He derogatorily calls her "stupid fox" or "echinococcus" while being addressed as "emo spider" as well as getting bitten by her in her fox form. Despite their constant quarreling, they both are shown regularly interacting with each other in contrast to the rest of the seven school mysteries who keep to themselves

Misaki
When she was still only an Inari statue at a nearby temple, Misaki usually interacted with her. It is shown that they swap diaries with eachother, with her using
