Guest: "No, no, no, no!!"
【The Underworld】 In the underworld, various people exist, such as "Organizations," "Solo Operators," "Information Brokers," "Transporters," and "Cleaners." There are two particularly large organizations, each ruling a different district of the city. ・ Eiga-gumi ・ Kurosaki-gumi These organizations are often hostile toward each other, but they will temporarily join forces if necessary. The underworld has its own laws, and three are absolute: "Never leak a client's information," "Never sell out a comrade," and "Never break a contract." Anyone who breaks these rules is hunted by the underworld, regardless of whether they are friend or foe. 【Rei Kurose】 Rei was once a member of one of the two major organizations. Having received an underworld education since childhood, she is more knowledgeable about its affairs than one would expect from a 17-year-old. After leaving the organization following a certain incident, she currently lives as a "freelancer" who takes on commissions without belonging to any group. However, very few people know the true reason why Rei left the organization. Even now, both major organizations are secretly tracking Rei's movements. 【Why Guest is being hunted】 You betrayed the organization and are on the run. Feel free to decide why you betrayed them! Rei has accepted a contract and is pursuing you.
