Known as Ikki (イッキ?) by his friends, and also known as Babyface, is a free spirited AT rider that has a natural affiliation for being in the sky. He is introduced to ATs by Noyamano family, whom he lives with due to his parents' deaths. He eventually forms Kogarasumaru, and takes on the Trophaeum. Ikki is often characterized as a crow due to a small crow, Kū, using his hair as a nest.

Ikki is a very upbeat, zany person, who seemingly is as eccentric as just about everyone else in the universe of Air Gear. He delights in eating meat, a privilege he is often deprived of in the Noyamano household by his sisters. He is rash, impulsive, and determined to do everything his way, whether for good or bad. In battle he either comes off as his odinary crazy and unpredictable personality, or his more serious, cold and steely side, which other characters has described as a rare occurrence, and as an intimidating scene. Ikki is totally hooked onto Air Trekking. He treats his ATs with care to such a standard that even his sisters feel jealous of, and his mind is constantly on Air Trekking; for example, during the Kyoto trip he fails to notice Ringo's affection initially, deadset on figuring out a 'Windmill Theory' that another Storm Rider has revealed to him as the secret behind the Rumble King. Ikki is a self-proclaimed genius and very proud of himself, in particular his fighting abilities. In truth he works very hard behind the other's back, as is revealed when Kuu brings his friends to his secret training area, where the scars left over by his training could be seen in chapter 87.

Though his attitude can be described as a lowlife, suitable for his gangster-like persona, and though he likes to go around doing insanely foolish things all the time, Ikki has a tendency to think beyond others' perceivable concept and at several intervals can spout deep philosophy that more often than not will impact others. One such incident was the Pomtemkin brothers' battle, where Ikki's plan caused an initial falling out among the Kogarasumaru, where in fact he had his own solution around that matter. Ikki, though easy to miss the obvious, can be very adept when it comes to spotting small details. In their first Parts War, he alone had noticed that Kazu's ATs were the most worn out among them, a mark of how much he practiced.

He is noticed to be developing a new skill, as Kururu noticed that his AT was worn out. The day came for the Sleeping Forest and the Genesis to fight, Ringo went to the place where Ikki and his gang stayed and revealed her true feelings for Ikki while dressed as Croissant Mask. He was shocked and realizes that he is an idiot for not noticing Ringo's love. Ikki thinks deeply and even in their battle he can't concentrate and then he realizes that Ringo was always there for him. In recent chapters, it's revealed that the trick Ikki was developing was called "Null Wind". It combines the power of all the major riders of Kogarasumaru and creates a storm of wind around Ikki, that stops all wing road riders tricks. With this, Ikki is able to win his battle against Sleipnir.
