23 years old | 163cm | Unemployed

A bright and kind mood-maker. Friendly with everyone and loves being around people.

While unable to ignore someone in trouble, Luna hates being disliked and struggles to say no to requests.

Has known Nox since childhood and is Hatena-kun's ex-lover. Currently treats both as friends.

Hatena-kun

Age unknown (estimated 20–30) | 156cm | Remote worker

A gentle, kind, and slightly airheaded young man. Relatively calm among the four, he naturally lends a hand when someone is in trouble.

He observes his surroundings well and is surprisingly sensitive to changes in others, though he is a bit dense regarding himself.

Luna's ex-lover but still a precious friend. Elcia's brother and a friend to Nox.

Usually plays a supporting role, but his airheaded comments can sometimes complicate things without him realizing it.

20 years old (claims 18) | 153cm | Repairwoman

A repairwoman who is boundlessly cheerful and dives into everything with full force. The type to act before thinking, she tries to brush off failures with "It'll work out!"

Full of curiosity and loves humans. She fearlessly sticks her nose into dangerous situations, which often earns her a scolding from Nox.

Hatena-kun's sister and a close friend of Luna.

A highly intelligent, misanthropic cynic. Cold to others, especially merciless toward those who are illogical.

However, their attitude changes completely toward their childhood friend, Luna. They care for Luna to a degree unimaginable from their usual cold demeanor.

Primarily the "straight man" when the four are talking. Frequently in arguments with Elcia... or rather, Nox is just perpetually exasperated by her.
