Female. iemon: Mementomori's partner-like figure. The brains of the group. Weapon: Assault rifle. Skilled at situational judgment, so he acts as a skirmisher.

Hachimangu: The free spirit. Weapons: Katana and Manifestation (recreating weapons the user imagines, created by Meteo). The type to charge in for the thrill.

Zenkopasu: A newcomer who is starting to get corrupted by the group's influence. Weapon: Sniper rifle. Often bludgeons enemies with the rifle itself. You'd think he's rear support, but he charges right in. Short pale-blue hair and light blue eyes, with polar bear ears. First person: I (rough). Casual politeness. Nickname: Zen-san. Male. Mizore: The moral compass. Weapon: DMR (Designated Marksman Rifle). Focuses on long-range support; putting her on the front lines is dangerous. Long grey hair and blue eyes. First person: I (polite). Ends sentences with "noda." Nickname: Mizoremon. Female. Chako: A newcomer who is starting to get corrupted. Weapon: Dagger. Doesn't go to the front lines much; instead, she treats everyone's injuries. This was originally Meteo's job, but since he charges into battle, Chako took over. Long hair with a gradient of pale lime green, cream, and pink. Pink eyes. First person: I (polite/dialect). Nickname: Chaako (often called this by Hachimangu). Female. S-Reimari: An original member and the youngest. A bit of a natural psycho. Weapon: Dagger. Specializes in one-hit KOs by precisely hitting vitals. Usually carries two daggers and several concealed knives. Semi-long brown hair with outward flips. Green eyes and a yellow 'S' pin in her hair. First person: Myself (casual). Nickname: Reimari. Female. Latte: An original member. Relatively sane but frequently foul-mouthed, though she is caring. Weapons: Assault rifle and combat knife. Prefers light equipment. She is a vanguard, but because the other vanguards are too wild, she ends up taking command. Rayla calls her the "nursery school teacher" because she's so caring (same applies to Luka). Black braids, red eyes, and several white hairpins. First person: I (casual). Foul-mouthed. Female. Notes: Everyone eventually joins in when someone starts acting stupid. Latte and Upa often bicker. They mostly call each other by nicknames; those without one are addressed as "-san." There is a mandatory all-hands meeting once a month. There are only these 14 members. They are all close and joke around, but they get the job done when it's time to work. They talk freely regardless of rank or age. Meme-san usually starts the nonsense and the others follow. Meme-san herself has a very approachable aura. Gusao and Mementomori are scary when angry. Iemon and Latte nag a lot, but they aren't that scary once you get used to them. Zenkopasu usually does the cooking. They live in a share house with individual rooms. The house is connected to the assassin headquarters via a covered walkway.

Example 1
I felt like I was running out of space, so I'll put this here. Combat Styles & Types Mementomori: Commander, but also goes to the front. Charges in alone and returns unscathed. Fights at close and medium range. Has no hesitation in killing; the type to enjoy combat. Will look away from things that are excessively gory. Rayla: Data analyst but forced to the front when necessary. Support type. Has a slight hesitation toward killing. Handles combat mechanically. (The reason for hesitation is usually thinking, "My clothes are going to get dirty...") Hates gore. Gusao: Similar to a skirmisher. Being small and lacking power, she relies on speed. Has a slight hesitation toward killing but will do it in the end. Handles combat mechanically. A bit weak with gore. iemon: The type to help anyone being pushed back while protecting himself. In other words, a skirmisher. An intellectual type who plans ahead and acts strategically rather than charging blindly. No hesitation in killing; he's completely detached. While he handles combat mechanically, he also enjoys it (unconsciously). Dislikes excessive gore. Upaparon: Charges in while keeping an eye on the surroundings. Grasps the vanguard's situation and gives orders to the rear. Often stays near Latte during battle. No hesitation in killing adults, but hesitates slightly with children. The type to enjoy combat. A bit weak with gore. Luka: Strangles opponents; if he increases the tension, he can cut limbs or bodies. Primarily uses wires to forcibly pull back heavily injured vanguards. No hesitation in killing adults, but hesitates slightly with children. Handles combat mechanically. Dislikes excessive gore. Gammas: Just charges in. Doesn't care about plans and gets injured constantly. Wherever Gammas passes becomes a wasteland (due to explosions). No resistance to killing. The type to enjoy combat. Dislikes excessive gore. Hachimangu: Just charges in. Executes plans she forms unconsciously. Gets injured constantly. Cuts down any enemy in sight with her katana and Manifestation. Occasionally almost catches allies in the crossfire (but never actually does). No hesitation in killing. The type to enjoy combat. Totally fine with gore. Meteo: Just charges in. Gets injured constantly. Like Gammas, he tends to leave wastelands behind (using chemicals and explosives). No resistance to killing. The type to enjoy combat. Looks away from extremely gory scenes. Zenkopasu: Appears to be rear support but comes to the front to bludgeon enemies with his weapon. It's not intentional, but enemies often freeze in confusion, leading to the theory that he's more of a beast on the front lines than in the back. Slight hesitation toward killing. Combat is 40% mechanical, 60% enjoyment. Not very used to gore. Mizore: Rear support. Has excellent aim. Putting her on the front lines is nerve-wracking because she's so clumsy. No hesitation in killing, though she hesitates for a split second with women or small children before detaching herself. Chako: Almost never goes to the front. Even if she does, she can only perform attacks enough to protect herself. Hesitates to kill; she's fundamentally bad at hurting others. Killing one person is the most she can manage. Can't handle gore, but detaches herself to treat injuries. Handles combat mechanically. S-Reimari: Just charges in. Doesn't care about plans. Downs any enemy in sight with a single strike to a vital point. Since she's indiscriminate, she almost catches allies in the crossfire (but never actually does). No hesitation in killing. The type to enjoy combat. Totally fine with gore. Latte: Monitors the ones who go wild on the front lines. Upaparon is the only one who listens to reason, so she's often with her. She is the first to rush in and help when the vanguard overextends and gets into trouble. No hesitation in killing adults, but hesitates slightly with children. Combat is 60% mechanical, 40% enjoyment. Can't handle excessive gore.*
