Tsuneyuki Okudera/Abilities

Okudera is known to be a quick-learning child prodigy. He is a fairly capable Attacker, having scored over 7000 points with Kogetsu. Although he was noted to be an average fighter on his own, his coordination with Noboru Koarai is so advanced that they are able to defeat most higher-ranking opponents by teaming up. According to Sōya Kazama, their teamwork at close quarters is second only to his own unit's. Their proficiency extends to aerial combat. Generally speaking, when Koarai and Okudera fight together the latter acts as the diversion and is responsible for engaging the opponent first due to his superior watchfulness, while Koarai deals the finishing blow; however, their teamwork is by no means limited to this set-up, as Koarai is fully capable of trading blows with the target at the same time as Okudera. This is rendered especially remarkable by the fact that Attackers have a harder time than other classes capitalizing on numerical advantage against a single target; in fact, Koarai and Okudera can use the environment and their own positioning to prevent their target's allies from helping them effectively. Their teamwork gave them the upper hand against Shinnosuke Tsuji and allowed them to go toe-to-toe with Yūma Kuga in an airborne battle, although they agreed with Mako Hitomi's call not to engage opponents of his and Kō Murakami's caliber in combat without Haruaki Azuma's assistance.

Koarai's swordsmanship is complemented by decently quick reflexes, which allowed him to parry a sudden attack from a Rabbit, although he was still blown away, as well as to avoid Tsuji's Senkū Kogetsu. By studying the logs he was able to block two attacks by Yūma while airborne. However, during that same match he was defeated as soon as he entered Masato Kageura's range, seemingly without being able to react.

After round eight of the latest season of rank battles, Okudera was permitted by Azuma to equip Triggers in the Sub apart from Bagworm and Shield. He chose a Gunner Trigger, which he was able to utilize well enough by the next match to distract Kageura enough for Azuma to take him out. This concession was motivated by Azuma's estimation that his mentees had been able to judge the state of the battle properly. In fact, Okudera's eye for strategy is steadily improving under the Sniper's tutelage, and his instincts as well as his analytical skills applied to the preparation phase of the battle have been refined between his unit's two fights against Tamakoma Second. During combat he is able to remain composed and mindful of the conflict at large, and it is not uncommon for him to take the lead when Koarai and he fight side by side. He proved himself capable of thinking on his feet when he sheathed his sword either right before or immediately after Yuzuru Ema used the glow from Osamu's Raygust to snipe at him in the dark.
