Description
Shirō Kikuchihara operates as an A-rank Attacker in Border's Kazama Squad. He sports shoulder-length brown hair and distinctive black slit-pattern irises. His Trion body uniform features a navy blue shirt layered with a black shrug jacket displaying a prominent cross design across the torso, paired with black boot pants bearing Border emblems on each sleeve.

Personality-wise, Kikuchihara frequently makes derogatory remarks and voices disapproval toward those losing to opponents he deems weak. Despite this outwardly rude demeanor, he lists "buddies and friends" as favorite things. He demonstrates particular interest in Osamu Mikumo, initiating private conversations—a rarity outside Kazama Squad interactions. His dislikes include tomatoes, capsicums, boiled fish, oysters, and people who appear superior.

In combat, Kikuchihara wields Scorpion and Chameleon Triggers as primary armaments. He possesses a Side Effect enhancing his auditory perception to five or six times beyond normal human capacity. Initially considering this ability useless, Sōya Kazama recognized its strategic potential within team dynamics, aiding their squad's ascent to A-rank. His combat approach emphasizes practical efficiency, bluntly assessing Mikumo's team: "If Kuga is the only member of the team who can hold his own in a duel... You'll be stuck in B-rank. You'll be in trouble as soon as Kuga is defeated."

Kikuchihara maintains significant loyalty to Kazama Squad members. His background includes enrollment in Border at an unspecified time, with his current age documented as 16 years and birthdate as December 14.

His interactions extend beyond his squad, notably including Mikumo, and feature confrontational exchanges like telling Hisato Sasamori to "retreat. You're weak, after all," and accusing Shiori Usami of being a "traitor who sold herself to Tamakoma."
