Kazuaki Ōji/Abilities

Matching his status as the captain of an upper B-rank unit, Ōji is both a competent fighter and a masterful strategist. Osamu regarded him as the most dangerous member of his team, defining him as a "tricky Attacker" due to his hybrid fighting style. Since, according to Konami, all upper B-rank units have an ace with the prowess of an A-rank agent, Ōji is likely the one in his team. Even after losing both his teammates, he was able to score two points through clever tactics, good timing and sheer strength, and nearly succeeded in taking out Yūma as well, as noted by Kitazoe. He is skilled and coordinated enough to fight off Osamu with only one hand while at the same time forcing Chika to keep her Shield up.

Like the rest of his unit, Ōji is known to be a top-level runner, which allows him to cross the map quickly and pick off the weakest targets first, as well as to find out the hiding spots of Snipers. This is particularly useful when combined with his ability to make educated guesses about the starting points of opponents wearing Bagworm. Oki doubted he could outrun Ōji in a long-distance race, despite having a headstart and Grasshopper in his Trigger set. Ōji can also attack while running on a wall, and his reactions are quick enough for him to dodge an attack from behind at close range, as well as to avoid a frontal Lead Bullet Lightning shot.

Ōji's foremost defining trait may be his intelligence. In terms of analytical skills, he offered the most in-depth breakdown of Tamakoma Second's strategies to date, pinpointed Osamu's key role in the tide of the battle, and came up with a second countermeasure against Chika's Lead Bullet, having realized she is unwilling to fire normal bullets. He may also have understood the mechanics of Osamu's red wire trick. During the preparations for a match, he is able to come up with multiple tactics and cover a wide range of probable scenarios. Due to their numerous matches against each other, Ōji is capable of predicting Ikoma's actions and seeing through Mizukami's tricks. More impressively, he was able to see through Osamu's plans several times during their first confrontation even after the match had started, proving to be a quick thinker, to the extent he could guess what Osamu was thinking while fighting him. Kitazoe speculated that is due to the two having similar thought processes, although this is what allowed Osamu to predict his actions at least once. However, a crucial difference between the two is that Ōji is also endowed with remarkable individual power, effortlessly defeating Osamu while also suppressing Chika.
