Being a member of the No. 1 B-Rank (formerly A-Rank and Expedition Force member) team, Tsuji is a very capable fighter. He has reached Master Class with the Kogetsu, and gave proof of his matery when he fought against Okudera and Koarai, whose teamwork is among the best in Border, at the same time with only minor injuries. He was able to score 2 victories against Hyuse using only Kogetsu, inflicting grievous wounds in at least their last match despite losing. In rank wars, while fully capable of engaging most opponents on his own, he primarily stalls the enemy or covers for Inukai. In fact, his main role is to support the rest of his team, and he is extolled as one of Border's three best supporters, Tsuji appears to have an excellent sense of timing, showing up only for a moment to slow down a stronger opponent, or to attack multiple adversaries at the same time.
Having reached Master Class with this Trigger, Tsuji is a very proficient user. He is capable of actively fighting with it with only one hand, and thus covering a larger area with each swing, which requires a good degree of skill and strength as, due to its weight, the Kogetsu tends to unbalance the user. With the Kogetsu, Tsuji was able to hold back both Koarai and Okudera, who, despite being less skilled users, can defeat opponents much stronger than them with their first-class teamwork.
Tsuji is always seen using this Trigger for a surprise attack before engaging the opponent, exploiting its range to remain safely at a distance. It also allows him to attack multiple targets at once and to control their position to some extent.
