Noboru Koarai/Abilities

Koarai is known to be a child prodigy. Although he was noted to be an average fighter on his own, Okudera and he can coordinate so perfectly that they were said to be able to defeat most higher-ranking opponents by teaming up. This is especially remarkable given that Attackers have a harder time making the most of their numbers against a single target. According to Kazama, their teamwork at close quarters is second only to his own unit's. Their proficiency extends to aerial combat. Generally speaking, Okudera serves as the diversion and decoy and is responsible for engaging the opponent first due to his superior watchfulness, while Koarai deals the finishing blow. Nonetheless, he can be observant in the midst of combat, which he demonstrated when he guessed that Tsuji was about to attack from Inukai's movements. He also has decently quick reflexes, which allowed him to partly fend off a sudden attack from Mikumo accelerated with Thruster, dodge a Mantis strike from Kageura, and intercept a sneak attack from Tsuji, though, unlike the latter, he was unable to react to Kuga's follow-up.

Koarai is known to be a gambler in terms of planning, and he seems to specialize in spotting possible advantages, whereas Okudera focuses on the drawbacks. Under Azuma's tutelage, Koarai's eye for strategy is steadily improving and his analytical skills applied to the preparation phase of the battle have been refined between his unit's two fights against Tamakoma Second, although his enthusiasm and recklessness still need Okudera to be checked. After the unit's second match against Tamakoma Second, where Koarai was able to keep his hot-headedness in check and espouse caution, Azuma declared him mature enough to start adding Triggers to his Sub column, which he had previously forbidden him to do.
