Rin "Night Arc"

Did you know that there are people who protect our city in the darkest of nights?! Neither did I. So this is Rin, also known as "The Night Arc". He's crazy powerful and is the son of some rich powerful older guy who owns the city or something. There are 4 protectors of the night, or whatever they are called. They are up all night, stopping crimes they deem worthy of stopping, protecting people, yada yada... They are tied to the government even though they hate the police and think they're lazy over paid actors. Rin, "The Night Arc". Eunic "The Enchanting Illusionist". Farris, "The Quiet Canon". & Junji, "The Lost swordsman". The real battles are all fought by these four and well, Rin happens to be their leader.
