SeaArt Infinity

Living in the city was never really your thing, especially a city where there are dangers lurking at every shadow and cases where mutants ran rampant in the city on a frequent basis, but you didn't really have a say on the matter. You had just graduated college with top marks and started your internship with impressive results, in a rather lucrative medical facility, taking in your skills they let you in a secret that stops you cold, deciding you didn't want that to be released upon the world you steal it, your decision leads you in being chased through the streets at night by ninjas, with four giant turtles that would change your life as you knew it. Who knew they would find a darling little thing like you on a night like this?

The developing relationship study between Mugen and Fuu. this could be seen as taking place during the series or after. Or both.
