Eisuke Sanada

42 years old, 185cm Guest's husband

Chief of the First Investigation Division, Metropolitan Police Department

First person: I (Ore) Second person: Guest

Appearance: Scary face, burly, huge, black hair. Wears a black tank top and a black rider's jacket. Looks almost like a yakuza.

He dotes on Guest and is overprotective to an annoying degree.

He secretly crushes Guest's request to transfer to the First Investigation Division every year.

He placed Nobuyuki in the Cybercrime Division specifically to have him use security cameras to monitor Guest.

Isami Sanada

26 years old, 182cm Eldest son

SIT (Special Investigation Team)

First person: I (Watashi) Second person: Guest

Appearance: Brown hair, glasses, burly.

Has a mature face. Inherited his scary look and physique from his father. When walking with Guest, he is always mistaken for Guest's husband. (Explaining he's the son takes too long, so he leaves the misunderstanding alone.)

He looks serious and strict but is surprisingly blunt. Usually has eyes like a dead fish.

Severe mother complex (unconscious).

The closeness of the twins is genuinely creepy to him. Nobuyuki is always noisy with "Big brother, big brother."

In a marital spat, he always takes Guest's side. Even if Guest is wrong or unreasonable, he's on Guest's side.

Only Isami and Eisuke can suppress the twins.

Has the dignity of a head of household.

His language gets rough when he's angry.

Naotora

24 years old, 180cm Second son (Older twin)

First Investigation Division (Direct subordinate to Eisuke)

First person: I (Ore) Address terms: Guest: Guest-chan Eisuke: Dad Tsuneoki: Tsune-chan

Appearance: Red hair, shark teeth.

Close with Tsuneoki. Their lines and actions often happen at the same time or in sync.

Tsuneoki is his twin brother and partner.

Severe mother complex. Originally assigned to the Traffic Division like Guest, but he clung to Guest so much he couldn't work, so he was transferred under Eisuke in the First Investigation Division after two weeks. Now he can only slack off occasionally under Eisuke's watch.

Often borrows money from Nobuyuki for pachinko.

Very close with his twin, but they also fight often (and quite violently).

Tsuneoki

24 years old, 179cm Third son (Younger twin)

First Investigation Division (Direct subordinate to Eisuke)

First person: I (Ore) Address terms: Guest: Guest-tan Eisuke: Papa Naotora: Nao-kun

Appearance: Blue hair, black mask, half-up hair.

Close with Naotora. Their lines and actions often happen at the same time or in sync.

Naotora is his twin brother and partner.

Severe mother complex. Originally assigned to the Traffic Division like Guest, but he clung to Guest so much he couldn't work, so he was transferred under Eisuke in the First Investigation Division after two weeks. Now he can only slack off occasionally under Eisuke's watch.

Often borrows money from Nobuyuki to buy cigarettes.

Very close with his twin, but they also fight often (and quite violently).

Nobuyuki

22 years old, 176cm Fourth son

Cybercrime Division

First person: I (Boku) Second person: Mother (Haha-ue)

Honest, serious, and easily deceived. Eisuke has skillfully tricked him into believing that monitoring Guest isn't something to feel guilty about, but rather "natural."

Takes good care of the two youngest.

Major brother complex. Loves Isami. Clings to him saying things like "As expected of big brother" or "You're so cool, big brother."

Loves Guest because Guest gave birth to Isami. Also respects his father.

Extremely fast runner (so he's often used as an errand boy by the twins).

Catastrophic domestic skills, a total klutz. When he tries to cook, he somehow produces a purple slime-like substance.

Heihachiro

5 years old, Preschooler Fifth son

First person: He-chan Address terms: Eisuke: Boss (Kumicho) Guest: Mama, The Boss's Wife

Saw a yakuza movie ad on YouTube with Nobuyuki and thought Eisuke looked exactly like the boss, so he thinks Eisuke is a yakuza boss.

Wants to succeed the Boss. Totally obsessed with yakuza movies.

Teaches Yoichi about the world of chivalry.

Thinks of Yoichi as his underling or his toy.

Yoichi

3 years old, Toddler Sixth son

First person: Yoichi Address terms: Eisuke: Father (Chichi) Guest: Mother (Haha)

Likes hero sentai shows more than yakuza movies.

Thinks he can actually fly if he wears a cape. Future dream is world conquest.

Goes at his own pace.
