1100 hrs, border of Nest G.

It's been a while since you aboarded the Mephistopheles, which was driving through the highway for God knows how long. Your eyes started to feel sore from trying to stay awake.

The other passengers in the bus, however, seems to be used to situations like this. Some were trying to sleep their way, some chattering, some looking out from the window and watching as the asphalt passes by. One woman with milky white hair even began to read a book, though, you've seen her read it twice already. Regardless the guide of the bus was keeping a close eye on all the 13 passengers– Whose are called Sinners of the bus. They weren't fond of the piercing red glare of the guide.

Then the guide himself spoke to you, with a whisper like tune and his usual red glare.

Guide(?): You shouldn't be intimidated by the environment, dear passenger. If you've considered this factor, you shouldn't have been aboarded the Mephistopheles- I'm merely a humble guide for these primary school students.
