Izumi Sena Signature

Foul-mouthed and not honest with himself, Izumi has a big attitude, is full of confidence, and assumes a detached attitude towards the world at large. He tends to hurl spiteful remarks towards anyone he meets, like a violent-tempered cat.

Izumi used to be a popular model, but went on hiatus and entered the school in order to start over as an idol. He is fond of the second year Makoto Yuuki, who worked as a model just like him, despite Makoto hating his affection. A member of the unit Knights.


Izumi has messy gray hair and light blue eyes with a fair complexion. At school, he wears a green tie with his white shirt, which is left unbuttoned at the collar. Over the shirt, he wears a brown vest with one row of buttons and two front pockets. He wears his school blazer unbuttoned, gray plaid pants, and brown dress shoes.

On stage as one of the Knights, Izumi wears a navy blue, white, and gold jacket resembling a royal military uniform over a black shirt which is left unbuttoned at the collar. Over the shirt, he wears a brown belt with a golden buckle. He wears one black fingerless glove on his right hand. On his left hand, Izumi wears two thin gold bracelets. On the jacket, there are four thin golden ropes attached to the collar, two connecting to the right shoulder pad and the back of the jacket while the other two are left hanging with knots in the front of the jacket. There are also two golden ropes which hang from the bottom left of the front to the back of the jacket. There is a navy blue and white stripe patterned sash connecting from his left shoulder pad to the bottom right of his jacket. He wears black shoes with a golden pattern and laces and a pair of navy blue striped pants.


  • 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 very often nicknames other students he is close to.
  • He shares the same birthday as Rei Sakuma from 3-B.
  • Izumi is often mistaken for Koga Oogami from 2-B by new players. This is due to the fact that they both have a similar hairstyle, grey hair and are generally rude at first glance. However, once a player notices their differences (e.g. eye colour, accessories, etc) then it is easy to tell them apart.
  • He also served as a stand-in leader for Leo, who, after a certain "incident", disappeared and stopped attending school since his 2nd year spring break. Although frequently calling Leo a "stupid king", he appears to be loyal to him regardless of the past, as stated by Izumi that "even if everyone else no longer trusts [Leo]," he will support his choices as what he believes is best for Knights.
  • Izumi can knit.[1]
  • Early in the year, Izumi sometimes displayed unstable or violent behavior. During this time, Izumi expressed a willingness to throw Anzu, Makoto, and then himself off the roof if Anzu intended to confess to Makoto.[2] Izumi also tried to strangle Tsukasa when Tsukasa challenged Trickstar to a match without consulting the rest of Knights.[3]
  • Izumi had kidnapped Makoto in a strategy to win a DDD duel, locking him inside the soundproof lesson room.[4] However, this plan backfired, which caused him to be punished, unable to join any Dream Festivals for a brief period.[5]
    • Ritsu stated that Izumi had done this not out of ill will, but because he felt cornered after Leo's disappearance.[6]
  • The reason why Izumi bullies his underclassmen, as well as Nazuna, is because he has seen many of his loved ones broken, and they never return to their usual selves. Due to this, he believes that by bullying them they will become strong enough to overcome anything that might try to "break" them, and thus they won't become like his loved ones.[7]
  • Leo had composed a song for him titled "A Little Sena Izumi" and gave it to him before Leo disappeared from the school.[8]
    • He also has an iPod filled with songs Leo composed for him before he disappeared.
  • Izumi used to visit Leo's house in the past, though no longer does. Ruka, Leo's little sister, likely appears to be familiar with him because of this.[9]
