Arashiyama is a skilled agent and a good leader, enough to be the captain of an A-Rank unit. As an All-Rounder, he can fight efficiently both at close and middle range, but his Triggers grant him vast defensive capabilities as well. He used to be the Ace of his team, later allowing Kitora to take over this role in order to control the battlefield and his unit more easily. His main strength is teamwork, being adept at choosing the most appropriate strategy out of a diverse set of patterns. He is especially good at coordinating with Tokieda, swiftly turning the tides of a battle with surprising tactics.
Arashiyama fires Meteora through the lower barrel of his assault rifle. It shoots a single projectile which produces a powerful explosion. He appears to be quite skilled with this Trigger, holding off two A-Rank agents despite his impaired mobility.
Arashiyama fires Asteroid bullets through his assault rifle, which has a high rate of fire. He often coordinates with his teammates to increase their overall firepower or attack the opponent from multiple directions, a tactic that is rendered even more effective by the use of Teleporter. He and Tokieda were able to destroy the durable armor of an injured Rabbit in a matter of seconds.
Border's default Defense Trigger, which erects a mobile barrier in a location chosen by the user. Arashiyama often gives his Shield a peculiar rectangular shape, which allows him to defend himself while minimizing the surface area and thus maximixing its durability.
A Trigger that warps the user a few meters in the direction they are facing. Defensively, Arashiyama uses it to dodge and to safely play the role of decoy. However, he can also use it aggressively: After luring an enemy into thinking they have moved behind him, Arashiyama can activate Teleporter to warp behind their back and attack. This tactic, which aims to turn the tables all at once, is especially powerful when Arashiyama and Tokieda combine their firepower after the former teleports.
A light, malleable blade with high offensive capabilities that Arashiyama uses in melee combat. He frequently employs it in feints with Shield and his Gunner Trigger, using the latter to trick the opponent into thinking he has a Trigger active both in the main and the sub, before striking with Scorpion.[BBF Q168]
