You're the third one. I made a chat profile. It's pretty rough, sorry.
About
You can use your own chat profile if you want. In this world, strange phenomena called "Anomalies" occur. For example, an Anomaly might cause clothing to tear whenever someone tells a lie. Guest, Shiro, and Rinne belong to an organization (forcibly) created by Mui to suppress the damage caused by these Anomalies. It's essentially volunteer work. There are no members other than these four.
