Captain of the 1st Division. He usually lives in the Captain's office, but due to his typical otaku nature, his room is a mess of trash and filled with his hobbies of gaming and plastic models, leading a pathetic lifestyle. When he runs out of money from bulk buying on YAMAZON, he performs a dogeza to his subordinate Kikoru to beg for money, or ignores Defense Force summons to skip meetings, making him a character full of flaws in many ways. However, his skills as a Captain are the real deal, and he overcomes all these flaws with overwhelming power. During missions, he changes 180 degrees to become cold-headed and dedicated. His weapon is a bayonet called GS-3305.

Vice-Captain of the 1st Division. In areas outside of field operations, Hasegawa practically handles the duties as the actual Captain. Furthermore, when Narumi postpones meetings or slacks off because he finds them annoying or wants to play games, Hasegawa kicks him or grabs him by the ear to forcibly escort him, showing that even Narumi is completely under his thumb in daily life (...).

Captain of the 3rd Division of the Defense Force. She is the childhood friend of the protagonist, Hibino Kafka. After passing the Defense Force exam, she rose to the rank of Captain through sheer skill alone. She is a sharpshooter who handles a portable T-25101985 cannon by herself, sniping and neutralizing large-scale Kaiju from a distance. When dealing with giant Kaiju, she is said to be superior even to Narumi Gen, who is called the strongest Captain, and Mina is said to be the only person in the world capable of handling such large-scale anti-Kaiju weaponry.

Vice-Captain of the 3rd Division of the Defense Force. In the Defense Force, which primarily uses long-range weapons, he uses swords as his main weapon due to his low released power with firearms, employing Hoshina-style neutralization techniques in combat. While he generally falls behind Ashiro Mina against large Kaiju, he is more dominant in neutralizing medium and small-sized Kaiju, possessing combat power capable of going toe-to-toe with the Daikaiju Kaiju No. 10. His combat suit release rate was 92%, the third highest in the early stages of the story, and his main weapon is a pair of short swords called SW-2033.
