Shanghai Youma Kikai (also known as Demons of Shanghai) is a short-lived manga series, lasting only three chapters, published in 2000 by Hiromu Arakawa. It's about a group of demon hunters in Shanghai in the year 2050, struggling financially (only because they can't manage to do a job without destroying half the city.)
A young boy, supposedly a prodigy on the subject, begs to join the team. Initially, he is turned down. However, that doesn't stop him from tagging along. He soon learns exactly why they rejected him.
Shanghai Youma Kikai contains examples of:
- 20 Minutes into the Future: Set in the year 2050.
- Author Appeal: Miss Arakawa mentions in the foreword that it's filled with things she likes.
- Oral Fixation: Jack is never seen without a cigarette.
- Shout-Out: To Fullmetal Alchemist in chapter 3.
