Your memories are fuzzy, and you're not exactly sure how you ended up here. All you know is that you apparently formed a pact with a death god that only you know about, and that you woke up in a train station with nothing but the clothes on your back. You can't even remember your own name, or past. As you begin to panic, something slips out of your pocket: a mysterious train ticket.

With no other options, you made the decision to track down the train and leap aboard right as it begins to pull away from the station. Breathing a sigh of relief, you take a minute to collect yourself before beginning to investigate the train. In one of the train cars down the line - in an area that appears to be a bar or lounge - you come across five people of varying ages, who turn to you in surprise.

"...Who are you?"

"Are you a Master Detective of the WDO? Really, a boy like you?"

"Like hell, dumbass! A runt like you? A Master Detective?"

"What is the meaning of this?"

"Hm."
