Manabu Horikita/Relationships

Suzune Horikita
Suzune is his younger sister who seeks to prove herself in his eyes, showing that she greatly admires him. Despite this, Manabu views his sister as a disappointment due to her placement in Class D which greatly displeases him. It is unknown if they were ever close or if he ever had a brotherly affection towards his sister though it is shown Suzune has portrait of the two of them together, meaning he did care for her a while back.

Currently their relationship is rather turbulent, as Manabu has expressed contempt for his sister's academic failure placing her in Class D. He ordered her to withdraw from their school since his reputation which he worked hard to build was on the line and became angry at her refusal. He nearly physically attacked her in his rage, though Kiyotaka Ayanokōji quickly intervened. After a brief scuffle with him, Manabu left but not before admitting he was surprised she made a friend that would help her but she denied it as he voiced his disappointment in her antisocial ways.

In Episode 5, they are seen together again at the hearing of Ken Sudō and Manabu's very presence causes Suzune to get shaken up so much that she couldn't speak. When Ayanokōji helps her get her resolve back, Suzune is able to get her point those present and the hearing commences much further. Despite his sister's strong determination in the case, Manabu was still not impressed with her efforts. He did question Kiyotaka if she came up with everything by herself after the hearing was over but gets a vague answer.

When Class C withdrew the complaint against Sudō, Manabu assumed it was Ayanokōji's idea but the latter casted the credit to Suzune. Manabu simply glared at Ayanokōji for either because of his sister being mentioned or sensing that he was lying to cover up his own involvement.

During the summer outing, though they didn't interact personally, Manabu bore witness to his sister's speech of how its possible for Class D to reach Class A. After the speech, his only reaction was a glare at his sister who responded in the same way, its unknown what he thinks of her now.

Akane Tachibana
Akane is the student council secretary of the Advanced Nurturing High School. Not much is known about their relationship but they appear to get along fine as he had no problems in having Tachibana speak when addressing the hearing for Ken Sudō and seem to trust her opinion in helping him lead the student body.

However, at times it appears he can sometimes be stern with her when she questions his decisions as shown in Episode 6 where she was shocked at his decision to make Ayanokōji, a first year student from the lowest class of the school into a member of the council. Tachibana was silenced by a simple glare from Manabu, showing she can be intimidated by him at times.

Kiyotaka Ayanokōji
The two first met when Kiyotaka prevented him from attacking his sister, quietly admonishing him for his actions before demanding he release her. When Suzune asked him not to get involved, Kiyotaka complied by releasing his arm. Manabu then took the opening and tried to hit him but he nimbly avoided Manabu's strikes to the latter's surprise. Manabu was impressed by this display asking Kiyotaka if he studied martial arts to which the latter gave him a vague answer. Manabu soon recognizes him as the student who scored exactly 50 on all his entrance exams and on the recent quiz. He inquired him of this strange coincidence, hinting that he is aware that Kiyotaka is hiding his intelligence on purpose but the latter shrugs this off. Manabu called Kiyotaka's actions unique before he left the scene while being surprised his sister made a friend that would come to her aid.

They meet again, where they are present during a case for Ken Sudō. It is shown that Manabu has some expectations for Kiyotaka as he believed that his presence at the hearing meant that he had a strategy but his question is disregarded. When Kiyotaka supported Airi Sakura, Manabu attempted to attack Kiyotaka again as the latter dodges his strike and Manabu questioned as to whether he has something planned but gets a vague answer.

When Class C's complaint against Sudō was withdrawn, Manabu meets with Kiyotaka in the hallway and informs him about this. He congratulates him on his victory but Kiyotaka once again gives Suzune all credit for the act. Glaring intently at Ayanokōji, Manabu had asked Tachibana if they had an opening for Secretary on the Student Council to which she confirms. Manabu offered the position to Kiyotaka, showing that he truly sees him worthy of higher status than others, despite his class and background. This was especially noteworthy as Manabu is notoriously known for turning down many applications, even those from highly esteemed students like Honami Ichinose. Kiyotaka turned down the offer in favor of living a normal school life. Manabu accepted his decision for now though he told him not to disappoint him.
