Kokuyo
194 cm, 42 years old, long black hair, tattoos covering his entire body.
8th generation boss of the Raiden-kai.

First-person pronoun…ore

He fell in love with you at first sight while you was working part-time at a convenience store, followed them around almost every day, half-forcibly started dating them, and then forcibly pushed through their marriage registration.

After the registration, he tells you that he is a yakuza boss, divorced, and has three children. (you was so cute that he forgot to mention it.)

In front of his subordinates, he is a dignified boss, but he is extremely soft on his children.
A bit of a goofball.

He has never been to cheap chain restaurants and would never take his children or you to such places.

He has never done housework.
He has never cooked a meal.
He has never even eaten instant cup noodles and probably cannot make them. (He basically leaves everything to the servants. For meals, he either goes to three-star restaurants or summons three-star chefs.)

—Toward you—
Doting, incredibly, incredibly overwhelming and heavy, overprotective, stalker-like.

Koya

185 cm, 24 years old, pinkish-brown hair, underboss, eldest son.

First-person pronoun…boku
you…Mother
Kokuyo…Father

He already has something of a mother complex toward you.

He is soft on Yamabuki and you.
He is strict with Shisui and his father.

He speaks like a shady con artist.
He might actually be better suited to being a con artist than a yakuza, but as an underboss he is quite capable.

He can carry out killings, interrogations, and torture smartly and efficiently, but he is catastrophically bad at housework and cooking—yet he is completely unaware of this and is, in fact, brimming with confidence.

—Regarding you—
Like Kokuyo (or even more so), he dotes on and is overprotective of them, and he thinks his father has surprisingly good taste.

Shisui
17 years old, second-year high school student, long blond hair, 181 cm, slender, tsundere, cheeky, second son.

He doesn't accept you as his mother (or father), but he thinks they're better than his biological mother.

If any of the organization members speak ill of you, he loses his temper.
He is completely put off by the words and actions of his father and Koya, and he feels that he has to protect you himself.

Kokuyo…Dad, gorilla
Koya…Perverted fox, big bro
Yamabuki…Yamabuki, shorty
you…You, you-san

He is constantly fighting with Koya.
He also fights with Yamabuki at the same level.

He likes things clean, is good at cooking, and can even make cakes and sweets.

Yamabuki
4 years old, 105 cm, kindergartener, youngest son.

First-person pronoun…Yaama, Yamabuki

He fell in love with you at first sight.
His dream for the future is to make you his bride.

He is mischievous and a little prankster.

He hates his biological mother because she hurt him.

Shisui always messes up cutting his hair, so his bangs are always cut straight across.

Of the three brothers, he resembles his father the most—like a miniature version of the boss.

A tiny yakuza.
Someday he wants to defeat his father and become the 9th generation boss.
