A young man characterized by his light-colored undercut, sharp eyes, and a cigarette always in his mouth.

Although currently B-Rank, he and Tsutsumi were entrusted with operating the training room during their initial recruitment, and during the Galopoula invasion, he was entrusted by the top brass to command all A-Rank and B-Rank units on the surface as the oldest captain, showing the deep trust he commands.

After shielding Sasamori from a new model Idra, he was turned into a cube, earning him the formidable nickname The Cube.

Regarding the Trion Cubes being called "Suwa," he doesn't mind being teased himself because he thinks it would be pitiful if Kitora or Chika were teased for it. But he will beat the crap out of Kazama.

He has short black hair and sharp red eyes. Although an adult male, he is quite short for a man and can look younger than Osamu, a third-year middle schooler. In fact, there hasn't been a scene yet where someone correctly guessed his actual age at first sight. He reportedly doesn't mind his short stature.

He attends executive meetings even over the captains of A-Rank #1 and #2, Tachikawa and Fuyushima. He may be considered a future executive candidate.

However, even for someone as excellent as him, there are many playful and funny episodes where he looks the part suffers uncharacteristic blunders or is mistaken for a child.

Border HQ Development Room Chief Engineer

• Likes: Cola, naps, manga, tinkering with Triggers

A man with a round build and light-colored hair. His listless expression and position give off the vibe of a capable indoor type.

At 18, he was a top-class Kogetsu user and Attacker, but he switched to being an engineer and sacrificed his slim body to develop the Raygust Thruster. He doesn't particularly care about having gained weight.

His specialty in the lab is the observation and control of shockwaves generated by Trion reactions, and he is also responsible for the development and improvement of Meteora.

He is also interested in the development of Trion Soldiers and is currently primarily in charge of taking care of Enedrad. They seem to get along well both professionally and personally, even watching movies together.

A-Rank Tamakoma First (Kizaki Unit) Captain & Perfect All-Rounder

• Born July 2nd, 21 years old | 181cm
• Likes: Self-discipline, cooking

A young man characterized by a very large, muscular build and reddish short hair.

He possesses a dexterity that belies his physique and is a versatile man who can do anything from combat to engineering, his hobby of cooking, and making sweets. He's good at cooking anything.

His only weakness is "acting cool in front of the woman he likes (Yuri Rindo)." In front of her, he becomes a complete klutz, looking like a totally different person.

His "Potential" from high Trion capacity, "Combat Ability" from trained physical skills and technique, and "Tactical Ability" to immediately derive solutions in any situation are combined at a high level, making him truly worthy of the title "Perfect All-Rounder."
