Izumi's canon appearances

Ensemble Stars! is a mobile game wherein the player is a female second-year student transferring into the esteemed Yumenosaki Academy which used to be an all-boys school famous for creating popular idols until she came along as the first student enrolled in the producer course. Facing the fact that the school is not what it seems to be, the player decides to help a newbie unit who wanted to rebel against the school's corrupt unit system and change everything from here on out.

I have compiled links of everywhere Izumi has appeared in that has been translated so far, and I will also be relating canon instances in his personality section to elaborate his mindset further. Though if you do have any questions or if I need to make a more detailed history, please let me know.

CANON PERSONALITY:

Izumi, at first glance, is an aloof person. And not to mention downright arrogant and rude towards almost everyone. Sure he may have that knightly aura (he does belong in an idol unit named 'knights' after all), but that doesn't stop him from hurling rude remarks to pretty much anyone he meets. His underclassmen get the worst of it, since bullying them is actually stated to be one of his hobbies (fellow third-year Nazuna also gets affected, since he looks very young for his age). He's easily irritated and would complain that something is "so annoying" if it doesn't go his way, to the point of being a catchphrase of sorts for him (and is even one of his voiced lines in the game).

And Makoto... Poor, poor Makoto Yuuki. Izumi is absolutely enamored with him, a second-year who used to be a model before they entered Yumenosaki Academy. Izumi loves him like a little brother, but the way he expresses it is terrible and borderline stalker-y at best -- In Duel, in response to Makoto joking about Anzu calling him up to the roof to confess to him, Izumi explicitly states that he'll throw her off the roof, then Makoto, and then himself. And in WANTED!!!, he claimed that Makoto said "I love you, onii-chan" again like the good old days and even had a recording of it, but most of it's just synthesized sound patched together to sound like it, making his classmate, Chiaki Morisawa, think that Izumi's like a kidnapper. And that's just the tip of this creepy iceberg.

Speaking of kidnappers, Izumi did pull a stint like that in the main story. In order to win the DDD, a very important Live (an idol performance), he kidnapped Makoto and kept him prisoner in the locker room for days. However, even though his plan was thwarted by Makoto's idol unit, he was let off with only a temporary ban from idol activities, as seen in Sweets Pattissier. This does affect the standing of his unit, and while he was only the stand-in leader of knights until their real leader comes back, his leadership role was also stripped away after the kidnapping incident. And so he gets his just desserts.

Now that we've established that Izumi is a very unpleasant individual to be with, let's go deeper.

Despite hounding after Makoto like a crazed stalker, Izumi really does care about him. Since he's an only child, the brotherly relationship that developed between him and Makoto during their modeling days must have been very important to him. Makoto was a very important part of what kept Izumi in the modeling industry, and to Izumi, he was someone who was just like his own family. Unfortunately it involved into an obsession -- to be thought of being a big brother. Makoto isn't the only victim of this; Izumi also considers Yuta Aoi, one of the first-year twins, to be a liable replacement. That said, he can actually display actual big-bro moments, such as telling his youngest unitmate, Tsukasa Suou, that the latter should depend on his seniors more. Though it would weird his juniors out who only knew him as a creep or a bully.

Speaking of bullying, it's also his way of showing that he cares. In Phantom Thieves vs Detectives, Izumi explains that he has seen his loved ones break to the point that they are unable to go back to the way they used to be, and he didn't want this to happen to anyone else anymore. He thinks that by picking on them, they'd be able to learn to pick themselves back up and fight back. It's a weird kind of logic, but considering what he had to deal with in the past (with Makoto quitting modeling and the real unit leader, Leo, breaking down during the "war"), it's not hard to see where he's coming from.

Speaking of Leo, Izumi holds him in high regard despite calling him a stupid king. As mentioned, he was willing to take Leo's place as the decoy leader of knights until the latter comes back from his ~mysterious disappearance~. Although he was bitter that Leo ran away in the war's aftermath, Izumi still remains loyal and will continue to fight for him, just like a knight willing to do everything for his king.

So in summary, Izumi really does care for his peers! He just has a weird and/or harsh way of putting it. Which is why a lot of people have accused him of being a tsundere, to which he vehemently denies. They may not excuse his more deplorable actions, but they do explain his mannerisms, and those traits make Izumi Izumi.

SKILLS/ABILITIES:

Izumi is an idol first of all, so he's already trained how to sing and dance in front of large audiences. And even before that he used to be a model, and it's been mentioned in some of his stories that he's been in the industry for quite some time now, so he already knows how the ins and outs of it actually work.

His specialty is stated to be ballet, and he used to take lessons before and even taught some of the basics to a couple of units including his own for the school festival.

In addition, cooking is also in his field of expertise. Izumi is very meticulous about his body, only eating his own home cooking instead of eating outside. It's to the point that he'd rather drink water for lunch instead of indulging on cake that his unitmate had lovingly offered to him.

And lastly, he knows how to knit. Just goes to show that he has a mother-hen side of him when he's not being a huge creep.
