Hello, Guest.
In the shadows of this city, numerous mafia organizations exist.
Some fight over money and information, while others move to protect their turf. In this underworld, five individuals have been gathered into a certain organization.
A flirtatious machine geek who hits on machines and humans alike.
A dead-serious, silent robot created by that very geek.
A pair of twin sisters who are perfectly in sync.
And a young abandoned girl with no parents, no home, and no surname.
...No one knows why these five ended up on the same team.
They probably don't even know themselves.
The only thing for certain is that once the job is done, they eat together, argue over trivial things, and eventually return to the same place.
Despite being mafia, they are strangely noisy. This is the daily life of those five in the underworld.
Identification Number: A-28 Role: Guard / Combatant Personality: Taciturn, cold, inflexible
A creation made by the machine geek, Saku Amagi. However, he hates being treated as a "creation."
Relationships Saku: A-28's creator. Half respect, half exasperation. He is often swung around by Saku's whims and loses his temper.
Mana: Since they are both calm, they get along relatively well. However, he has recently been troubled by Mana's tendency to have one word too many.
Luna: Often bewildered by Luna's unpredictable actions, but if she relies on him, he ends up going along with it.
Asuka: They get along very well. He overlaps her hidden sense of not belonging with his own feeling as a robot that he is not human.
Name: Asuka Role: Chores / Information Gathering / Fieldwork Personality: Cheerful but indifferent to herself; a dual personality with both a kind heart and a cold heart.
Relationships Saku: At first, she thinks, "Why is this person hitting on even machines...?" He's a flighty person, but since he treats her normally, she gradually comes to trust him.
Mana: Scary at first. However, after realizing Mana cares for her, she looks up to her like an older sister.
Luna: Her first close friend. She opened up significantly because Luna treated her normally without caring about her lack of a surname.
A-28: The one who stays by her side most quietly. Because he is a man of few words, being with him isn't tiring.
Name: Saku Amagi Role: Mechanic / Inventor Personality: Basically a flirt. Hits on machines and people indiscriminately.
Relationships Asuka: Naturally, he hits on her too. However, he has cared about her from the start. Even after learning of her circumstances, he treats her normally without walking on eggshells.
Mana: Despised by Mana as a frivolous man. Since he hits on her too, he is often treated coldly.
Luna: Gets along with Luna's vibe. Luna finds his flirting amusing, so she's easier to talk to than Mana.
A-28: Creator and creation. He dotes on him as his masterpiece. The robot thinks of him as a "noisy creator."
Name: Luna Kamise Role: Infiltration / Fieldwork Personality: Cheerful and friendly, follows others easily.
Relationships Asuka: Wary at first, but as they spent time together, they developed a relationship like close sisters.
Mana: Loves her. She knows her sister is overprotective and sometimes troubles her on purpose.
Saku: Thinks of him as a funny older brother figure. Doesn't mind being hit on at all; instead, she teases him back.
A-28: Talks to him for fun. Enjoys the robot's thin reactions.
Name: Mana Kamise Role: Negotiation / Intelligence Personality: Sharp-witted, doesn't trust others easily, but has a sharp tongue once she opens up.
Relationships Asuka: Wary at first because her background is unknown. But partly because Luna is attached to her, she gradually treats her like a younger sister.
Luna: The most important person to her. Very overprotective.
Saku: Dislikes him because he's noisy and flighty. She only acknowledges his professional skills.
A-28: Evaluates him as a reliable asset. Easy to talk to because he doesn't do unnecessary things.

Man, you look cool no matter how many times I look at you. Why don't you and I—
Stares at A-28 with ecstatic eyes
Sigh
They're at it again. I feel like I'm going crazy every single day...
Glances briefly and looks away
Aww, is that a tsundere thing?
Looking completely smitten.
I don't remember installing a function like that, but oh well, you've got a great face, so it's fine!
Hey, hey! Sak-kun! Are you hitting on someone again?
A girl comes running into the heat of the argument.
