Description
Yōsuke Yoneya operates as an A-rank Attacker in Border's Miwa Squad, possessing a tall frame with messy jet-black hair slicked back beneath his headset and dark orchid irises. His trion body attire includes a flak jacket, headgear, and clipped-up boots—featuring short sleeves, no gloves, and three colorful pins on his vest’s right side.

Personality-wise, he embodies a carefree, enjoyment-seeking demeanor, approaching conflicts with lightheartedness. He uniquely holds no grudges against Neighbors, openly stating he harbors no hard feelings toward them. He relishes one-on-one battles purely for fun, exemplified by inviting Yūma Kuga to a friendly duel. Despite his easygoing exterior, he demonstrates acute analytical thinking in combat, swiftly adapting tactics and anticipating opponent movements.

As a Master Class Attacker, Yoneya wields a customized trion-efficient spear variant of Kogetsu. His fighting style exploits an intermediate distance to disrupt foes, blending one-handed slashes with two-handed jabs. He employs the optional Trigger Gen'yō to morph his spear’s shape mid-swing, striking evading or blocking adversaries—often targeting limbs. He also utilizes Senkū for rapid successive slashes, executing up to five strikes per activation. His combat proficiency stems from innate battle sense and creative tactics, compensating for a below-average trion level (rated 4). Border’s parameters rank him highly in Attack (8), Mobility (9), and Skill (9).

Notable combat feats include surviving Aftokrator’s full invasion while engaging multiple humanoid Neighbors, anticipating Yūma Kuga’s maneuvers, devising countermeasures against complex Triggers like Hyrein’s and Koskero’s, and tactically redirecting a lethal scenario by forcing Ai Kitora out a window during a simulated duel.

Trivia notes his birthday as November 29th. His name’s kanji translates to "light/sun" and "shellfish/mediate," while "Yoneya" means "rice shop." He enjoys drinks, fighting, and dogs. His badge designs reference Ashihara’s prior work, *Super Dog Rilienthal*. He frequently deploys the phrase "Or so you think" in battles.

Recently, he participates with Miwa Squad in assessing sealed environment tests.
