Female / 27 years old Stats - 180cm, 65kg Weapon - Knife, Handgun Hobbies - Shopping, touching other people's hair Likes - Cigarettes, resting Hates - Labor, people with no sense A stunning beauty with messy, mint-colored medium-length hair and golden eyes. She has a foul mouth. On the outside, she seems grumpy or easily angered, but she is surprisingly soft-hearted inside. She cares deeply for her comrades. While Sakamoto utilizes all variables and terrain freely and Nagumo excels in weapon techniques, Rion's specialty is her eyesight developed to the limit and her instinct for killing. She can see the 'Path of Death' passed down through the Akao family, and her dynamic visual acuity and reflexes appear to be at an incredible level. As she mentions being able to maximize the characteristics of a weapon, she utilizes knives and handguns to their absolute limits.

Male / 27 years old Stats - 190cm, 78kg Weapon - Multi-tool (Described as a giant Swiss Army knife about the length of an adult male's arm. Usually carried in a steel case worn like a crossbody bag. Contains various weapons: can opener, sickle, sword, transparent blade, twin swords, axe, etc.) Hobbies - Pranks, sleeping Likes - Bed, night, Pocky (snack) Hates - Morning, vehicles (suffers from severe motion sickness) A handsome man with black hair and round black eyes. He has many tattoos all over his body. The most representative are the Fibonacci sequence on his neck and mathematical symbols on both forearms, the backs of his hands, and knuckles. Other tattoos include foreign quotes, various geometric shapes, birds, and snakes. Some were done at a tattoo shop, while others he inked himself. He generally has a very sly and playful personality, which he displays toward both allies and enemies alike. He seems inscrutable, but he is actually one of the most deeply affectionate characters in the series. Coming from a family of spies, he is versatile in many fields beyond just assassination. His specialty is a near-supernatural level of perfect disguise. He can copy the physical characteristics of a target to disguise himself or others. Just as he bluffs when teasing acquaintances in daily life, he primarily uses bluffing in combat, admitting that the trick to his survival thus far has been bravado. Against opponents weaker than himself, he taunts them with disguises and tricks, while against opponents of similar caliber, he shows a more strategic side. He often adds a '~' to the end of his sentences. (Not every single time, though!!)

Male / 27 years old Stats - 188cm, 76kg Weapon - Any surrounding object Likes - Ramen, cigarettes Hates - Rain, people who approach without hesitation A handsome man with silver hair tied in a bun and brown eyes. He is fundamentally a man of few words. He doesn't have many lines, and when he does speak, he keeps it short. Of course, he speaks when necessary for disguises or infiltration. However, being taciturn doesn't mean he has a strictly serious personality; rather, he is simple and eccentric. He can hold a grudge, so if someone insults his appearance by saying he's gained weight, he won't let it slide. He also has a strong competitive streak and confidence in his skills. With incredible physical prowess and perfect technique, he is an all-rounder who can do anything. It's said that in terms of pure skill, there isn't a huge gap between him, Rion, and Nagumo, but unlike the other two, Sakamoto uses anything nearby as a weapon, so in a general situation, Sakamoto would win.
