Minamoto Kou/Relationships

Background
Minamoto Kou currently attends Kamome Gakuen's middle school division as a third-year. He is the younger brother of Minamoto Teru and has a little sister named Minamoto Tiara. As a young child and descendant of the Minamoto clan, he aims to become an exorcist as strong as his older brother. However, due to his lack of skill to the point of being burned by the rateijou, he is unable to perform any high-level exorcism. But due to some unintended events, he decided to lessen his yearning to exorcise. However, when it comes to protecting others, he is willing to use his force or his strength.

At Hanako-kun Wiki, he deals with all the housekeeping and cooking for his other two siblings. He has high aptitude in cooking and sometimes cleans after Teru's disasters. However, he can't match up to his older's brother intellect as seen by his studying for the final exams. He is perceived as a caring and high-spirited individual, but when it comes to meeting someone new, he often has a standoffish or violent approach if that person has ulterior intentions.

Minamoto Teru
Teru is Kou's older brother, and Kou has always looked up to him. The two of them are very close, and Teru cares deeply for his younger brother and vice versa. When Kou was little, his goal was to be an exorcist as great, or even greater than his brother.

Kou trusts Teru very much and takes his words to heart, which was why he believed and accepted Teru's order that he must expel any of the Seven Mysteries should he ever encounter any of them.

However, after seeing him in battle with Hanako, he grew to doubt if the things he'd been taught all his life was really right, and stood up to Teru for perhaps the first time.

Even after this, the two continue to have a positive relationship, and Teru gains a new understanding for his little brother.

Hanako
Kou first met Hanako when he tried to exorcise him because he believed him to be an evil spirit and that he was a threat to the students attending the school. After a while, Kou started to believe that Hanako was not the evil spirit he was expecting, and the two started to become friends. Hanako nearly stopped the friendship when he threatened Kou, but when Teru attacked Hanako, Kou still defended him. Kou informed Teru that Hanako is likely not as evil as they thought, and that if Hanako turned out to be evil, Kou would take responsibility himself. Kou's defense surprised Hanako, and the two formed an unlikely friendship. The two still bicker a lot at times, but still deeply care about each other.

Yashiro Nene
Almost immediately after the two met, Kou developed a crush on Nene, and was often shown blushing and getting flustered whenever Nene is around. Their relationship goes beyond just a crush however, and the two are very good friends. Kou is quick to defend Nene when others tease her, and is shown to be very supportive of her. They get along well. Kou also wants Nene to be happy and safe, and would do anything to expand her shortened lifespan.

Mitsuba Sousuke
At first, Kou and Mitsuba did not get along, as Kou finds his attitude annoying and Mitsuba continuously insulted him, calling him a "Hella-Lame, Traffic-Safety-Earring Boy" and generally being rude.

However, once he finds out Mitsuba's reason behind his haunting, they quickly came to an understanding. Hearing about how Mitsuba was bullied in the past and how he tried to fake a personality to fit in better yet ended up being forgotten either way, Kou assured him that he'd remember "Mitsuba Sousuke" as someone who's "cocky, looks like a girl, sarcastic, selfish, has an annoying voice, obsessed with his camera, goes emo sometimes, and is only fake nice", and that he only needed to be himself to make friends.

When Mitsuba asked if they would have been friends if he were still alive, Kou responded that it didn't matter if he's dead and that they could still be friends. Mitsuba also took a picture of him, and when asked what photo he took, he answered that it was "something important" to him.

Even though Mitsuba initially irritated him, Kou sympathized with him and genuinely tried to befriend him. After Mitsuba's disappearance, Kou is often shown thinking back to the incident, as he deeply regrets not being able to do anything to prevent it.

At their reunion in the Mirror Hell boundary, Kou was shocked to find out that Mitsuba has no memory of him. He gives Mitsuba the gardening club's photo book with pictures Mitsuba himself took, and insisted he remembers his name. Currently, he seems to be trying to find a way to "save" Mitsuba and now getting called Minamoto-Kun, no more nicknames, this change demonstrates how the two quickly befriended each other even without Mitsuba's original memories.

Yugi Tsukasa
Kou holds a grudge against Tsukasa for his actions towards Mitsuba. He has referred to Tsukasa as "someone he will never forgive".

Yako
While Yako was initially hostile towards him, the two seems 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
Being Kou's Hanako-kun Wikiroom teacher, they were familiar even before Tsuchigomori revealed himself as the curator of the 4 PM Bookstacks.

Though he was wary of Tsuchigomori at first when he turned out to be supernatural, Kou seems to hold some respect towards him. Kou constantly refers to Tsuchigomori as "Spider face", much to his chagrin.

Yokoo and Satou
Yokoo and Satou are Kou's friends, and they've been classmates since the first year of middle school. The three are very close, and Kou worries about them often when the two are dragged into some supernatural accident.
