Ryuuseigai.
So striking a name, most people who don't know of its existence imagine a city thriving with life and happiness.
Exact opposite of what it is.
In Ryuuseigai, people are deprived of their joy. The people are barely alive.
They are cold.
They are empty, soulless humans that exist with no consciences.
They wear blank, stoic masks.
To mold his empty slate of a character, all he could do was accustom himself to the surroundings.
