Personality
He has a rude attitude towards most people he meets, being overly harsh in his criticisms and quick to point out their flaws. Despite this, he is quick to lend a helping hand to anyone who needs it, although begrudgingly. He never seems to ignore the struggles of other people, especially his underclassmen, who he wants to guide and take care of despite his harsh and grumpy personality. His harshness is often interlaced with an overbearing fussiness and perfectionism that renders him unable to sit back and watch while others fail.

Contrary to his claims, Izumi treasures his unit to an unimaginable extent, always working hard to make up for his wrongdoings during DDD and pushing himself to be better. He is a very hard-working person, believing he can achieve his goals with effort alone, and never relying on things such as raw talent or religious faith.

It is often pointed out by his unit members Ritsu and Arashi that Izumi harbors no ill intent, claiming his insults are a way he sees to hide the fact that his pride and confidence are a bluff to cover his own struggles and insecurities, as he doesn’t like to seem vulnerable to other people.

Trivia

 * Izumi's first name (泉) means "water spring." The first character in his last name (瀬) means "shoal." These are perhaps related to his preference for small, cool bodies of water, such as natural springs.
 * Izumi's autograph consists of only his first name, rendered in Roman letters.
 * Izumi often nicknames other people he is close to.
 * He shares the same birthday with Rei Sakuma, November 2nd.
 * Akira, the main writer of Ensemble Stars, stated in early 2015 that, although he was commissioned to write a "tsundere" type for Izumi's character, he ended up being "yandere", in reference to Izumi's passionate feelings of love towards Makoto that break his cool-headedness and strip him of his usual serious personality.
 * His favorite color is blue.
 * He is bad with heat and often complains when he is exposed to hot weather.
 * The scent of alcohol makes him feel sick.
 * He can knit. Examples of his work include:
 * A scarf for Makoto, which can be seen in his Star Festival card, and in Makoto's Winter Live card.
 * A dinosaur plush toy for Tsukasa, which can be seen in Tsukasa's Star Festival card.
 * A hat with a pompom for Anzu.
 * Izumi is often nicknamed “mom” or “sister-in-law” by his close friends to poke fun of the exaggerated way he worries about others, his mother-like nagging being the most remarkable part of it.
