Noboru Koarai

"Slinking off to lick our wounds doesn't sit well with me. If we gotta bail out, I wanna do it in a blaze of glory... Well, that's what I'd normally say..."

- Noboru Koarai to his teammates

Noboru Koarai is a B-rank Attacker and a member of the latest generation of Azuma Unit.

Appearance
Koarai is a light-skinned boy of average build. He has slit pupils and short-to-medium dark blonde hair that is slicked into an upturned point in the front. He seems to favor wearing light, dark-colored jackets, although he has also been seen donning hoodies.

In his trion body he wears a navy blue, long-sleeved jacket with black lines bordering the zipper and the high collar, which he keeps open, and running horizontally around it both on the inside and the outside. Vertical black stripes run from the collar to the wrists of the jacket, interrupted only where Border's logo is emblazoned on the outer side of each sleeve a little below the wearer's shoulders. On the right breast are two piped patch pockets closed by flaps, bigger than the ones that can be found in the vicinity of his left hip, while on the left is the B-rank logo. Underneath the jacket is a black shirt with a round neck. The uniform is completed by dark gray boots and headphones and a pair of black pants.

Personality
Koarai is high-spirited and easily excitable, and wears his heart on his sleeve. He has a competitive side, which is most visible when he discusses strategy with Okudera in front of their captain and when he fights in rank battles as well as when he cheers for others. Nonetheless, he shows no hints of resentment when he loses, instead congratulating the winner with enthusiasm and admiring more skilled Attackers. He can be defensive about his own abilities, although he is willing to recognize his shortcomings for the good of the team. He can act a little smug when things go his way.

Koarai has a well-deserved reputation for being reckless in combat, attacking a Rabbit on his own after it pounced on Okudera against his captain's advice and preferring to fight to the last even when retreating is the best move. However, he was recently noted to have grown more prudent, even though agreeing to retreat left him feeling dejected. In the planning phase of rank battles he has occasionally exhibited a penchant for suggesting courses of action based purely on how entertaining they had the potential to be. It is possible that this tendency of his has also subsided, as in round eight Azuma Unit chose Exhibition Hall, a map where Azuma is known to excel.

Trivia
