Sourcebook
Intro
Regarding the Magical Machine World, Simply put, it is a parallel future of the worlds of 2013 (where Abilities exist) and 2018 (where Jujutsu exists).
The world is dominated by two main nations: the Empire of Rowa and the Kingdom of Kyoken. Rowa specializes in defense and magic. Kyoken specializes in offense and swordsmanship.
The laws are not much different from modern Japan. One difference is that the legal drinking age is 16. The language is the same as Japanese. It feels like a fantasy world with machinery added to it.
The Situation:
Tetcho, Osamu, Chuuya, Yuji, and Hajime were transported to the "Magical Machine World" by a certain Ability or Jujutsu.
