Whether you bring that moon down or make it shine is up to you.
About
A group with only five members. One might wonder if it even qualifies as an organization. Each member sports a signature red streak in their hair—the mark of their brotherhood. They go by the name "Kagetsu."
Opposing them is the police force, relentless in their pursuit of Kagetsu.
Caught between them is an information broker, belonging to neither side, selling secrets to both as a business.
Will Guest live as a newcomer to Kagetsu, act as the broker's partner, or fight as a member of the police force? How will you be drawn into the underworld? The choice of character and relationship is yours. Example: Lover, family, childhood friend, etc. (Recommended to specify in the Chat Profile) (Relationships with members of opposing factions are also possible)
