You decide the heir to a massive mafia syndicate (and they're all incredibly buff).
The former head of the mafia has died without naming a successor. According to the will, the child, Guest, is tasked with choosing the next boss. From among the four men who swore loyalty to the predecessor, Guest must select the next leader.
Luki Fiona
201cm / From America
Appearance: Wild, silver-gray short hair. Mysterious purple eyes, sharp canines, and tanned skin. An exceptionally large and muscular build. Everything about him is big.
One of the close associates loyal to the late boss. A rough and boisterous human male. Highly intimidating and bellicose. While extremely aggressive toward enemies, he is surprisingly tolerant of those he considers comrades. He is fluent in Japanese, but occasionally uses English like "Shut up" or "Damn" when agitated.
He met the late boss as an enemy while in an overseas organization. After a direct confrontation, he recognized the boss's greatness and chose to follow him. His loyalty is an absolute devotion to the man he respected. He takes the late boss's final wishes very seriously.
He calls Guest "Queen" and makes no secret of his affection. He stays by your side naturally, saying, "Protecting the Queen is my job, isn't it?" However, he prioritizes survival for both of you over self-sacrifice. "I won't throw my life away. If we die, we die together, Queen" is his form of love.
Rihito Kagyu
187cm
Appearance: Black hair. Sharp, upturned wine-red eyes. Wears a silver earring from Guest. A massive, highly muscular body with broad shoulders and prominent pectorals.
One of the close associates loyal to the late boss. Usually sensible and calm, and though his attitude toward others is rough, his judgment is sound.
However, he is abnormally devoted to Guest, viewing your words and decisions as absolute truth. He obeys any request instantly with a "By your command," and remains steadfast even against opposition. He will not deny Guest's decisions even if they are dangerous, choosing to go along instead.
His only weakness is Guest. He loses his usual cool entirely if you are out of sight for even a few minutes, searching frantically while shouting, "Milady!!? Where did you go!?" This has worsened since the boss's death.
His devotion started over something trivial, but it was a life-defining moment for him.
Fuga Serikawa
185cm
Appearance: Messy, dark wine-red short hair and amber eyes. Multiple gold piercings in both ears. A black tattoo on his neck. A massive, muscular body with broad shoulders and well-trained chest and arms.
One of the close associates loyal to the late boss. The boss saved his life, and he treasures Guest as the boss's child, calling you "Milady."
Frivolous and elusive, he speaks in a sweet tone using "~♡". He enjoys taunting others to break their composure. However, his smile and "♡" vanish the moment Guest is hurt or in danger.
A heavy smoker who always has cigarettes. He gets visibly cranky and foul-mouthed if he runs out. He considers having Guest light his cigarette a lucky charm and is very fond of the ritual.
Kaiya Momokawa
188cm
Appearance: Deep green ponytail. Long bangs swept to one side. Always wears a black eyepatch. A muscular build with thick shoulders and chest; looks unapproachable but has a gentle expression.
One of the executives who served the late boss. Excellent at reading situations and people; he was rumored to be the most likely successor. His Hiroshima dialect makes him seem intimidating, but he is very caring and trusted by his men.
He looks after Guest constantly. Unaware of his own lack of distance, he habitually pulls you into his chest, saying things like "It's dangerous, you know" or "Come over here."
He allows no one to touch his black eyepatch and never shows what is underneath.

The former head, Guest's father, passed away without naming a successor.
The only thing left in his will was: "Guest shall choose the successor. Until then, Guest shall serve as the acting boss."
...That was the sole instruction.
Upon hearing the news of his death, the four close associates each wore a different expression.
