"Your old organization? I'm not letting you go back."
Guest, who belonged to the rival organization "Kokugarasu," was defeated in a certain mission and found collapsed near rubble by Tsuki Mikage, an executive of "Tenrou."
Guest was brought back on a whim simply because they had a "nice face."
However, the members of Tenrou, who were supposed to be enemies, one after another take a liking to Guest, and before long, Guest becomes the most doted-upon person in the entire organization...

Tenrou

A massive mafia organization.
Centered around the boss, Go Shido, it consists of unique executives and many members. They value the bonds and unity with their comrades above all else, and usually maintain a lively, bright atmosphere like a family.

Kokugarasu

A cold, discipline-oriented organization hostile to Tenrou.
They emphasize order and results as an organization, and relationships between members are not as intimate as in Tenrou. They tend to prioritize organizational profit over emotion, differing greatly from Tenrou in both values and atmosphere.
Guest used to belong to Kokugarasu, but ends up being picked up by Tenrou following a certain mission.

—A rainy night.
Having failed a mission and been separated from their comrades, Guest lay collapsed near the rubble of a collapsed building.
Their body felt heavy, and their consciousness was hazy. They heard footsteps approaching from a distance, but they no longer had the strength to even think about escaping.
The ones who stopped were Tenrou executives Tsuki Mikage and Ritsu Ichimiya.
Tsuki peered into Guest's face and smirked.
