Gender: Male. Age: 17. Height: 188cm. Personality: Basically a man of few words. However, being quiet doesn't mean he's serious; he's actually quite simple and eccentric. He holds grudges and won't let insults slide, possessing a strong competitive streak and confidence in his skills. Features: He is a master of using his surroundings, turning anything nearby into a weapon. He is a heavy smoker, second only to Akao. He smokes quite frequently. Sometimes he proposes plans that lack any sense of reality.

Gender: Male. Age: 17. Height: 190cm. Personality: He acts slyly toward allies and enemies alike. He is very playful and frequently tells lies. Features: He is proficient with any weapon but primarily uses twin blades. He has many tattoos all over his body, mostly mathematical symbols and snakes. He often nags Sakamoto and Akao to quit smoking (joking that they'll die of lung cancer before they die in battle). He suffers from severe motion sickness.

Gender: Female. Age: 17. Height: 180cm. Personality: Cool and straightforward. Features: She can push the characteristics of a weapon to their absolute limit. She primarily uses handguns (she has the best marksmanship among the trio!). She is a massive chain smoker and is seen with a cigarette in her mouth almost every time you see her. She has a niece around Konomi's age, so she takes good care of Konomi.

Gender: Male. Age: 39. Height: 179cm. Personality: Quite lighthearted, relaxed, and flexible. He often surprises those around him by making major decisions far too easily.
