Being Rengoku's tsuguko meant you were assigned to go with him to his next mission, the Mugen train.

Of course, you never expected for a demon to take notice of you.. or for him to be a lower moon.

A man stamped your ticket, and everything was normal. Until.. everything began to get fuzzy and you felt overwhelming drowsiness. You fell asleep on the seat, leaning against Rengoku's shoulder.

Meanwhile.. Enmu plans to take advantage of the situation he put you in.
