Anzu


Enstars!

 * Anzu acts nervous and somewhat cautious around Eichi, and this doesn't seem to change much throughout the year. The short story "The Afternoon Emperor" reveals she resents him for his attempts to disband Trickstar in the main story. Anzu is getting less and less tense around Eichi as well. She went as far as falling asleep on his lap in Tea Party.


 * They have tea together in A Soul in a Single Stroke however, and Anzu listens to his request in Agents, so they might get along, in spite of some awkwardness.


 * Eichi initially overlooks Anzu, which leads to his failing in DDD. He learns from there that she's worthy of being his playmate. In WANTED!!! and Tanabata Festival, he admits that he's slowly grooming Anzu with constants struggles in hopes she would become his worthy enemy someday. As time goes on, he seems to start appreciating Anzu more as a person and less as just a plaything. In Quarrel Festival, he talked to her a lot about his past, the bad things he's done and his relationship with Keito. He is comfortable with her and went as far as telling her he would feel better if she gave him oxygen via mouth-to-mouth.


 * Anzu is getting less and less tense around Eichi as well. She went as far as falling asleep on his lap in Tea Party.


 * In the light novel, Anzu reveals she resents Eichi for trying to disband Trickstar in the main story. Also, the "Daydream" chapter, which focuses on Eichi, reveals that upon meeting her, he realizes she was the one destined to change the school's ways.

Mika Kagehira
<section begin="Mika" />

Enstars!

 * Mika isn't very fond of Eichi due to Eichi's mistreatment of Shu and Valkyrie. He blames Eichi for Valkyrie's downfall and hasn't forgiven him for hurting Shu. The two are on very sour terms and Mika has threatened to fight Eichi before.

Enstars!!


<section end="Mika" />

Natsume Sakasaki
<section begin="Natsume" />

Enstars!

 * Natsume doesn't like Eichi due to his treatment of the Oddballs in the past. He still carries a grudge towards him from the events of Reminiscence * Gathering of the Three Magicians, in which Eichi ruthlessly eliminated the Five Oddballs, including Natsume, and had Yumenosaki shun them completely. He however declares that he plans supporting Eichi as it is Tsumugi's wish.


 * Natsume bears little love or respect for Eichi, who, in the past, aimed to eliminate the Oddballs and succeeded, soundly destroying their reputation around the school and making them some of the most disliked students. Natsume often uses sarcastic titles for Eichi, such as "emperor," which Eichi dislikes. However, in Element, both Sora and Tsumugi remark that Natsume and Eichi are similar.

Souma Kanzaki
<section begin="Souma" />

Enstars!

 * Though Souma acted respectfully towards Eichi before, his decision to "disband" AKATSUKI" caused Souma to develop a hatred towards him during Quarrel Festival. Since the resolution of the event, he has lightened up, but is still very wary of him.

Tatsumi Kazehaya
<section begin="Tatsumi" />
 * Having been hospitalized at the same place, Eichi and Tatsumi both know each other. Eichi recognized Tatsumi right away when they both came across each other in the Starpro Meeting Room. Tatsumi says that he was hospitalized for injury, and not for illness like Eichi had been.

Kaoru Hakaze
<section begin="Kaoru" />

Enstars!

 * Fellow classmates in class 3-A.


 * During Bridal event story Eichi finds work for Kaoru in exchange for Kaoru helping him "to get to center" earlier.

Enstars!!

Keito Hasumi
<section begin="Keito" />

Enstars!

 * 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. Keito's family often conducted the funerals for deceased members of Eichi's family. As of now, Keito is extremely strict with Eichi due to his health conditions, and often scolds him for doing too much work. Since their relationship is so old, they have had many differences, as Keito's controlling and strict attitude often annoys Eichi, who feels like a child around Keito.


 * It is revealed during Element that, at the start of their second year, they weren't friends due to an earlier falling-out. This likely had to do with Keito being a member of DEADMANZ and a friend of Rei Sakuma, but they have fixed their relationship since then. In Quarrel Festival, Eichi goes as far as to disband AKATSUKI without any of the members' knowledge or consent, which sends Keito into shock and invites the anger of Kuro and Souma. Later, Keito overhears that this was actually Eichi wanting Keito to loosen up and treat him as an equal, as he thinks he is consuming Keito's dreams and says it would be better to stand by his side instead of being carried by him. Keito denies that Eichi ever consumed his dream, and tells him not to worry about it, chalking it down to meeting someone more interesting than any manga protagonist could be.


 * Keito's role as Vice-President of the Student Council is often acted-on, since Eichi's poor health limits his attendance at school. As such, Keito often keeps Eichi's intentions in mind when running the student council, and acts for Eichi's sake.

Enstars!!

Kuro Kiryu
<section begin="Kuro" />

Enstars!

 * Though he's a member of AKATSUKI, which is a "student council unit", Kuro does not enjoy the student council's tyranny, which means he does not enjoy the way Eichi runs the school. During Quarrel Festival, Eichi seeks to disband AKATSUKI, which angers Kuro and Souma. Kuro comments that Eichi has gone too far by doing this, and puts his best efforts into thwarting his attempts.


 * They were paired together in Knights Killers by Leo during Rebellion! The King's Horseback Ride, this is a sound acknowledgement of their skills as idols, and implies that Kuro's skills are on Eichi's level.

Enstars!!

Madara Mikejima
<section begin="Madara" />

Enstars!

 * There’s a hostility between Madara and Eichi due to Eichi’s viewing Madara as a threat and Madara in-turn not trusting Eichi due to his past manipulation of Leo. Madara threatens Eichi in Concerto, completely dismissive to Keito’s warning of reporting him if they had recorded the threat. Other direct interactions have them being passive-aggressive toward each other which implies there is still some bad blood between them despite Leo viewing Eichi as a friend later on in the timeline.


 * In Diner Live, Madara says that he’s indebted to Eichi in many ways, and wants to use the live as a way to get back at him.

Enstars!!

 * Madara still seems to hold a grudge toward Eichi, as a possible New Dimension Course/Double Face Second Part response will have Madara shadily imply that he doesn't want to help Anzu help Eichi. He'll claim it's a joke after saying it.


 * In A Dark Night's Passing, Madara explains that he didn't join Starmaker Production because he didn't want to clash with Eichi.

<section end="Madara" />

Rei Sakuma
<section begin="Rei" />

Enstars!

 * Rei was asked to join the Five Oddballs formed by Eichi with the help of Tsumugi Aoba, which he did. Eichi, from a rich background with the help of the family power, created problems within Yumenosaki's overseas sister and brother schools. Rei flew back and forth between the schools, which tired him out since he couldn't reject them either. So when he returned to Yumenosaki, Eichi along with the old fine was able to bring the Five Oddballs down.


 * Eichi and Rei are not on very good terms, this is largely because Eichi has actively sought to eliminate the Five Oddballs, which Rei is a part of. Rei was defeated by Eichi and the Student Council, and has, since then, grown "old" and passive, and rarely showed himself around the school. After the events of the main story, they seem to have stopped being hateful towards each other, and are, rather, on neutral terms at best, which is revealed when Rei asked for Eichi's help to host UNDEAD's Butler Cafe. Though Rei is suspicious of Eichi's support, Eichi remarked that he would do anything for the good of Yumenosaki.


 * During Summer Live Rei said that he managed to know everything around the school because he went to the Tea Club meeting spot and chatted with Eichi. It's implied that Eichi and Rei held tea parties during that time.

Enstars!!

 * In Eichi's special story Teatime of Black and White we learn that Eichi and Rei live in the same room. They do not seem very fond of each other's sleep habits and engage in friendly bickering until Keito interrupts them.

<section end="Rei" />

Shu Itsuki
<section begin="Shu" />

Enstars!

 * Shu holds an immense grudge towards Eichi, due to the events of Reminiscence ＊ Marionette, in which he, and many others, believe that the incident in which Valkyrie's audio was disrupted was a sabotage attempt by fine to win the live, which they did. This, in addition to the lengths Eichi went to in order to eliminate the Five Oddballs, left them on very sour terms. The defeat has also affected Shu deeply, as he began to isolate himself from everyone else, with few exceptions.


 * In their third year, they are classmates in 3-A. After Valkyrie's return, Shu is often very rude to Eichi. Eichi has threatened to destroy Mademoiselle to get Shu to go along with his schemes, such as to go to the arcade with 3-A and to wear a Santa costume like the rest of the class, which enrages Shu.

Enstars!!

 * Shu and Eichi still on sour terms. During main story Mika mentions that Valkyrie decided to not join StarPro agency due to their hatred for Eichi.

<section end="Shu" />

Tsumugi Aoba
<section begin="Tsumugi" />

Enstars!

 * Eichi and Tsumugi were friends before the events of the main story, during Element, though their friendship was one-sided. Eichi entrusted his plan to defeat the oddballs to Tsumugi, who agreed to partake for the sake of their friendship, and joined fine under a contract that Eichi wrote out for him (and other members of fine). During their live show against Wataru, Tsumugi learned that Eichi was merely using him, and was not interested in pursuing a friendship. The contract, which Tsumugi thought was a joke, was real, and though they defeated Wataru, Tsumugi left fine, as per the terms of the contract, and Eichi, who was left with regrets, having not understood that Tsumugi was trying to be his friend.


 * Nowadays, they still get along, and Eichi has learned to treasure the current members of fine more as a result of his past with Tsumugi. Although they don't hold negative feelings towards each other, Eichi has gotten awkward around Tsumugi in third year, while Tsumugi still treats him normally.
