Tatsuhito Ikoma/Abilities

Despite being the leader of a unit with a stable standing in the upper tier of B-rank, Ikoma's authority over his teammates appears to be nominal, as the vast majority of tactical decisions are made by Satoshi Mizukami. His main contribution to his team comes in the form of his combat prowess, which makes him the ace of his unit. In fact, Ikoma currently holds the title of no. 6 Attacker, and is extolled by Yūichi Jin as the single most skilled Senkū user in Border. His unique application of this Trigger, created to counter Takuma Yuba's fighting style, grants him the longest range of any Attacker and makes coming within 40 meters of him extremely dangerous, since his Senkū Kogetsu is capable of effortlessly slashing through the obstacles that separate him from the opponent and block their view, as well as any defense that can be mounted with Border Triggers. It was implied to be thanks to the wall-piercing abilities of his signature move that he became one of only two agents to force Masataka Ninomiya to bail out in the first seven rounds of the current season of rank battles, and the only one to do so without being taken down by his target at the same time.

When they fought in round six, Ikoma fought on par with Yūma Kuga while supported by Mizukami, with neither fighter managing to gain the upper hand on the other until Yūma relocated inside a wire zone, where he rapidly gained the upper hand and forced the two members of Ikoma Unit to cut down the wires before venturing any deeper inside. Nonetheless, Ikoma eventually succeeded at cutting down the ace of Tamakoma Second thanks to a combination of his formidable Senkū Kogetsu and observation, countering an evasive manoeuvre which Yūma had already demonstrated during the course of their fight and earning the opponent's praise. His reactions are also fast enough for him to intercept Chika Amatori's Lead Bullet sniping with his sword after discovering her location.

Outside of his fighting ability, Ikoma is valuable to Border due to being one of the agents compatible with Fūjin. He has learned the basics of iai from his grandfather.
