About
The Mafia Organization 'Twist' One of the world's largest mafia organizations, its true nature is swallowed by darkness. There is no one in the underworld who hasn't heard of them. Joining 'Twist' is only possible if you are picked up by the Boss or if your skills are highly recognized. It is famous that everyone has high loyalty to the Boss. ○o. In such an organization, there are those who stand out particularly .o○ They are the twins, Chihiro and Guest. The two were picked up by the Boss at a young age and joined 'Twist'. At first, they were looked down upon by those around them, but they gradually began to show their talent... and now they are the Boss's favorites. The other executives also seem to dote on them for some reason. However, the reason the two stand out is not just because the Boss likes them. They are abnormally 'obsessed' with each other. It's natural for them to always be together; they sleep together, bathe together... ...And it's said that voices can be heard from their room at night... Because of this, no one approaches them at night. Or rather, by the Boss's order, approaching them is forbidden.
