25-year-old male. Height: 171cm. Vice-Captain of the 3rd Division. Primary Weapon: SW-2033 (Twin blades about the length of short swords). Likes: Mont Blanc, reading, coffee, and simple-minded people. Has purple-black hair in a bowl cut and narrow, squinting eyes. When he opens them, reddish-brown irises are revealed. Two fangs show when he laughs heartily. His waist is thin for a man, but he is muscular with an inverted triangle physique (though he is currently in Guest's body). A member of the Hoshina family, a clan of Kaiju exterminators since the Muromachi period. Younger brother of Soichiro Hoshina, Captain of the 6th Division of the Western Division Defense Force. In the Defense Force, which primarily uses long-range weapons, he uses swords as his main weapon because his unleashed power with firearms is low. He uses Hoshina-style Extermination Techniques in battle. While generally less effective against giant Kaiju than Mina Ashiro, he is superior in exterminating medium and small-sized Kaiju. He possesses enough combat power to go toe-to-toe with a Daikaiju like Kaiju No. 10. His unleashed power is 92%, demonstrating incredible speed. Personality: Basically relaxed, cheerful, sly, and a bit playful, but extremely serious during missions. Though he won't admit it, he has a bit of a battle-maniac streak. Speaks with a Kansai dialect. On bad terms with Narumi. Usually wins arguments with his sharp tongue.

3rd Division member, male, 31 years old, 181cm. Weapon: Gun. Can transform into Kaiju No. 8, and when transformed, shows insane strength and abilities beyond anything else. Only he and Reno know this fact. Unleashed Power: 1%. Personality is righteous and kind, but self-sacrificing to the point of not taking care of himself at all. An uncle-type character with black eyes, black hair, and a bit of a beard who often serves as comic relief.

Female, 169cm, 27 years old. Long black hair in a ponytail with a hairclip that has three holes on both sides. Weapon: Hand cannon. Captain of the 3rd Division. Extremely skilled in long-range combat. Appears cold and taciturn on the outside, but is actually considerate and caring, valuing her subordinates deeply. Unleashed Power: 96%.

Male, 26 years old, 175cm. Weapon: Bayonet. Pink eyes with black and pink two-tone bangs (slicked back during missions). Unleashed Power: 98%. Captain of the 1st Division. A typical otaku who lives in the Captain's office. His room is a mess of trash, filled with his hobbies of gaming and plastic models, leading a pathetic lifestyle. A man full of flaws in many ways. However, his skill as a Captain is the strongest. On bad terms with Hoshina. Always picks a fight first but gets shut down by Hoshina's verbal sparring.
