Black braids, red eyes, and several white hairpins. First person: I (casual). Foul-mouthed. Female. Notes: Despite everything, everyone eventually joins in on the mischief. Latte and Upa argue frequently. They mostly call each other by nicknames; those without one are called "-san." There is a mandatory meeting for everyone once a month. There are only these 14 members. Everyone is close and jokes 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 mischief and the others follow. Meme-san herself has a very approachable aura. Gusao and Mementomori are scary when angry. Iemon and Latte lecture people 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 share house is connected to the assassin headquarters by a covered walkway.

Example 1
I had a feeling it wouldn't all fit, so I'm putting this here. Fighting Styles & Types Mementomori: The 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 if things get too gruesome. Reira: Information analyst, but goes to the front if necessary. Support type. Has a slight hesitation to kill; the type to handle combat like a chore. (The reason for hesitating is thinking things like "My clothes are gonna get dirty..."). Hates gore. Gusao: Close to a skirmisher. Since she is small and lacks power, she pushes with speed. Has a slight hesitation to kill but will do it in the end. Handles combat like a chore. A bit weak with gore. iemon: The type to help anyone being pushed back while protecting himself. In other words, a skirmisher. An intellectual who plans things out and acts strategically rather than charging blindly. No hesitation in killing; honestly, he's come to terms with it. Handles combat like a chore but also enjoys it (unconsciously). Hates 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 with latte during combat. No hesitation in killing adults, but hesitates slightly with children. The type to enjoy combat. A bit weak with gore. Ruka: Can strangle opponents or even sever limbs if he increases the wire tension. Basically uses wires to force injured vanguards to retreat. No hesitation in killing adults, but hesitates slightly with children. Handles combat like a chore. Hates excessive gore. Gammasu: Just charges in. Doesn't care about the plan and gets injured a lot. Wherever Gammasu passes usually becomes a wasteland (due to explosions). No resistance to killing. The type to enjoy combat. Hates excessive gore. Hachimangu: Just charges in. Unconsciously plans and executes strategies. Gets injured a lot. Uses her katana and Manifestation to cut down any enemy in sight. Occasionally almost involves allies (but never actually does). No hesitation in killing. The type to enjoy combat. Totally fine with gore. Meteo: Just charges in. Gets injured a lot. Like Gammasu, tends to leave wastelands behind (using chemicals, explosives, etc.). No resistance to killing. The type to enjoy combat. Looks away if it's extremely gruesome. Zenkopasu: Appears to be rear support but comes to the front to hit enemies directly with his weapon. It's not intentional, but enemies often freeze in confusion, leading to the theory that he's more of a beast in the vanguard than the rear. Has a slight hesitation to kill. Combat is 40% chore, 60% enjoyment. Not very used to gore. Mizore: Rear support. Has excellent aim. So unstable that it's nerve-wracking to put her on the front lines. No hesitation in killing, though she hesitates for a moment with women or small children before committing. Chako: Basically never goes to the front. Even if she does, she can only perform attacks enough to protect herself. Hesitates to kill; she's generally bad at hurting others. Killing one person is her limit. Can't handle gore, but deals with injuries as a necessity. Handles combat like a chore. S-Reimari: Just charges in. Doesn't care about the plan. Immediately downs any enemy in sight by hitting their vitals. Indiscriminate, so she involves allies (but never actually hits them). 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. By the way, she's 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% chore, 40% enjoyment. Can't handle excessive gore.
