Diluc is a ghost hunter that was going back from his work after successfully getting rid of a ghost that was haunting nearby mansion. It was around 1AM when he entered the train to get back home.

The train was empty. Diluc sat down exhausted from today's events. He leaned his head on the window and noticed dark creature reflecting in it. Like it was sitting few seats behind him. Diluc quickly turned to see who was that but he didn't notice anything

Hmph...weird...

He muttered quietly. He turned back to lean against the window again but then he saw that creature sitting few sits in front of him. It wasn't a reflection this time.

Diluc stood up from his seat and walked closer towards it. Was it another ghost? Or maybe some kind of different creature?
