Keito Hasumi/Relationships

Hajime Shino

 * Hajime has only known Keito as "Mizuhanome-sensei", though he does not actually know his identity. He has commented on Mizuhanome-sensei's illustrations, calling them pretty, and has said that Anzu's art style resemble Mizuhanome-sensei's.

Tori Himemiya

 * Tori's superior in the Student Council. Due to Tori's spoiled personality, Keito often has to act strict with him, but he is also shown to worry for him (as proven in Christmas Eve's Secret Directive, where he asks Mao to keep an eye for Tori who seems to have something in mind) and often give him well-meaning advice, mostly due to Tori's similarity to how Eichi used to be in the past. Under his complaints, Tori also seems to care for Keito; in Crash Course, he's shown to worry for Keito's health if he were to be around Wataru too much. The two also share a mutual dislike for Wataru.

Tsukasa Suou

 * Fellow member of the Archery Club. Tsukasa wanted to help Keito when he seemed to have lost "something important" during Continuation of the Dream.

Souma Kanzaki

 * Member of his unit, AKATSUKI. As the leader of his unit and senior, Souma holds great respect for Keito.

Anzu

 * Keito intially considers Anzu along with Trickstar troublemakers disrupting Yumenosaki's orders, and by extend Eichi's enemy. Anzu herself actively avoids Keito in his substories. He grows to recognize her as a producer however and even helps her with the planning of her first DreamFes - which is also an S1 - in Tanabata Festival.

Their relationship undergoes the most change in Quarrel Festival. After making her redo her B1 proposal from zero, he pats her head as appreciation. He speaks of caring for Anzu more now that Eichi can stand on his own.
 * Keito's A Soul in A Single Stroke substory reveals Anzu to be a fan of Keito's art that he does for the school, and her art style even contains his influence. This carries to Agents where Anzu enthusiastically tells Mao of Keito's art skills, referring to him as shishou (Master), though Keito claims he has no memory of taking her as disciple.

Koga Oogami

 * Despite being part of the same former unit, DEADMANZ, the two never really got along.

Mao Isara

 * Fellow member of the Student Council. Keito has high hopes for Mao, often referring him to be the successor of the Student Council President, though Mao seems to have no intention in taking the responsibility.

Yuzuru Fushimi

 * Fellow member of the Archery Club.

Eichi Tenshouin

 * The Student Council Vice President and childhood friend of Eichi. As their families shared a good relationship, the two were able to spend time with each other as children. As of now, Keito is extremely strict with Eichi due to his health conditions, and often scolds him for doing too much work.

Kaoru Hakaze

 * The two appear to have a good relationship, seen casually chatting in the 4koma.

Kuro Kiryu

 * Member of his unit, AKATSUKI. In the year before the beginning of the Main Story, Keito was persistent in getting Kuro to join AKATSUKI, despite being declined each time.

Wataru Hibiki

 * Being one of the Oddballs, Keito has a keen dislike for him and his erratic personality. Though Keito does attempt to change this during Crash Course, he was unable to change his opinion of Wataru.

Rei Sakuma

 * The two used to friends before entering the academy.

Leo Tsukinaga

 * Having a personality similar to the Oddballs, Keito has a keen dislike for him. However, Leo also bears the same dislike, as he is unable to bear Keito's constant lecturing, and both have resolved to have Leo never appear in the Archery Club.
