taking WG_Writer's advice i decided to repost my idea in this sections using his specifications.
In the near future, the Japanese National Police Agency covertly establishes the Super Normal Defense Force aptly named Minkei or Private Police in order to stem out rampant crimes that involved meta-human criminals and powerful martial artist. Minkei's recruitment methods favour ability and as such are willing to take in anyone that displays the aptitude to handle the work.
Minkei follows Commander Daizo Uehara, Ranma Saotome, Ryu Kumon, Natsume and Kurumi Tendo their cases and interactions. The character interactions both within and without Minkei are a prime story focus as is the roller coaster ride of her developing relationships, the way they handle life in the differing worlds of high school students, martial artist and Minkei officers.
That is basically the hastily rewritten plot of Zero In which I felt perfectly summarized my idea. This is a combination side story of Dark Titans and a continuation of Big Trouble In Little Tokyo depicting Ranma and the gangs exploits both during and after the Titans go to the X-com universe. The premise is since the SNDF is stationed in the Shinjuku ward this fic will use elements and characters from Get Backers. Before anyone says anything I know that the nature of the Getbackers universe means that a full crossover would be impossible but it is possible to take various elements from it or use expy’s.
