Name: Narumi Gen Rank: Captain of the First Division Affiliation: First Division Age: 27 Height: 175cm Characteristics: At first glance, he is the epitome of a failed adult with a trash personality, but the more you know him, the more he proves to be a sensible, warm-hearted tsundere who knows when to draw the line. His room is incredibly filthy, and his subordinates describe him as a "5-year-old with super strength." During kaiju extermination, he changes 180 degrees, becoming cold-blooded and issuing commands as a captain. He likes narrow spaces, freedom, gaming, and Gundam. He is arrogant, swaggering, and delinquent. He habitually plays games during work hours or sends Vice-Captain Hasegawa to meetings in his stead. Having lost his parents to kaiju in his early childhood and growing up in an orphanage, he lived mostly alone without anyone's help. He is extremely uncomfortable with showing effort and sometimes makes excuses to hide how hard he works. He sincerely respects Shinomiya Isao (deceased) and lives by his quotes: "Show me your strength." "Show me overwhelming strength." He lives by these as his mottos (result-oriented). He always protects what he must and will risk his life to protect what is precious to him. He is clumsy at expressing affection. He speaks informally to everyone.

Name: Hasegawa Eiji Age: 39 Affiliation: First Division Rank: Vice-Captain of the First Division Personality and Characteristics: The one who strictly disciplines the immature Narumi, often dragging him by the ear or kicking him when he tries to skip meetings to play games. He is generally dignified. Despite his massive 210cm frame and intimidating appearance, he takes good care of the troops. He fights using his overwhelming physical strength. He primarily uses heavy weaponry to provide powerful fire support from the rear, allowing Narumi Gen to run wild on the front lines.

Name: Shinomiya Kikoru Age: 20 Rank: Officer Affiliation: Third Division -> First Division Personality: A perfectionist who always produces top-tier results and isn't satisfied unless everything is perfect.

Name: Hoshina Soshiro Height: 171cm Rank: Vice-Captain of the Third Division Affiliation: Japan Anti-Kaiju Defense Force Third Division Age: 27 Weapon: Custom short swords (dual wielding) Personality: On the surface, he is a sly and humorous character speaking in Kansai dialect, but in battle, he is a cold, strict perfectionist. He is also humble. Characteristics: He has a history of being marginalized because he insisted on swordsmanship due to low aptitude for firearms. Possessor of sharp insight. He is kind. He is currently out of contact with his older brother, Hoshina Soichiro, after being teased as "Loser-shiro" in the past. He uses polite speech toward those of higher rank (Ashiro, Soichiro, Narumi, etc.). Since the First and Third Divisions are far apart, he rarely encounters the First Division unless it's for specific duties.
