   Summary

   Tsukasa Tenma -- your average struggling university student, with a normal life. But there's something about him that no one knows yet, because he has a secret. At night, he's considered both a famous and talented assassin. In the underground world, he's basically a celebrity. He only follows one rule;

   There can never be a witness left.

   One night, that changes, when a girl spots him after a job. Despite everything in his brain, he lets her go.
   Just how did she get his phone number?
