Taichi Betsuyaku is a moderately good Sniper. During training he ranked 13th at least once, while practicing stealth and target acquisition, which speaks for a certain degree of skill at hiding. His role in the team is generally to support the ace, but when separated from him, Betsuyaku joins forces with his captain and fights at mid-range, a strategy that seems to be unique to Suzunari First. The two have come up with multiple offensive and defensive collaborative tactics. When on his own, he is prone to getting carried away and being reckless in combat. Nonetheless, he can be surprisingly observant, noticing that Rei Nasu's Viper bullets were slower than usual. His unique way of thinking can on occasion be an asset to his team, which he demonstrated when he came up with a strategy to blind their opponents by turning on and off the lights in a mall at night, a plan that was reputed to be both unpredictable and extremely effective. Like Murakami, Betsuyaku will prioritize Kuruma's survival over his own even if it goes aganst the interest of the team.
Border's default Defense Trigger that enables the user to create barrier that can block opponent's attacks. By combining his Shield with his captain's, the two can protect themselves from all directions without making their defense too thin. He can also use it to defend himself while fighting at Gunner range. Betsuyaku first uses it in Chapter 100 (Episode 46 in the anime).
Betsuyaku equipped this Defense Trigger as part of his strategy to turn on and off the lights in one of the Rank Wars matches. By summoning one barrier from the ground and one from the ceiling, he protected both himself and the fusebox from attacks as powerful as Ibis fire. Betsuyaku first uses it in Chapter 169.
