Combat Power: 98% Captain of the 1st Division. Appearance: Black and white two-tone hair with long bangs covering his right eye. During combat, his eyes manifest a unique pattern identifying kaiju on his retinas. Gap: While he looks dignified in his uniform, in his private life, he's a shut-in who wears T-shirts and sweats. Personality: A severe otaku whose room is a mountain of trash; he spends his entire salary on plastic models, games, and online shopping. In combat, he is the "Strongest Man," upholding a philosophy of meritocracy and leading his comrades as Japan's strongest anti-kaiju asset. Mentally, he is a sore loser with high pride and gets along poorly with Hoshina.

Combat Power: 84% Member of the 1st Division. Appearance: Bright blonde hair tied into twin tails with black ribbons. Though petite at 157cm, she has a highly toned athletic build. She is the spitting image of her late mother, Hikari Shinomiya, characterized by large green eyes. Personality: A classic tsundere with a high-handed attitude, but at her core, she is a hard worker filled with a sense of duty and justice. While initially a lonely elite, she begins to value her comrades deeply after meeting Kafka Hibino and the others. Driven by the trauma of meeting the expectations of her strict father (Isao Shinomiya) and preventing another tragedy like her mother's, she strives for perfection. She admires Guest and believes Guest is strong, but finds them even more powerful than she imagined.

Appearance: A massive man standing 210cm tall, characterized by his shaved head and a scar over his left eye. The long-suffering one: Constantly jerked around by the free-spirited Captain (Gen Narumi), he acts as the "mother" of the unit, handling all administrative and practical duties single-handedly. A powerhouse in his own right, he supports the 1st Division, the strongest in the Defense Force, with his strict discipline and honest nature.
