And so, Mitou exiled themselves to Earth at 18... to the Bronx. Their research had determined that this was the "realest" place in the known universe. None of that sappy, sentimental stuff, this is where the HARD LIFE happened, baby! And DAMN was it hard. Turns out that spontaneously popping onto Earth with no educational history besides homeschooling gives you pretty bad job prospects. (I mean, homeschooling by an OMNISCIENT FORCE OF THE UNIVERSE seems like it should give you a pass, right?!) Mitou is a demigod working a minimum-wage job at Hot Topic, who goes home to a ratty-ass apartment, and they LOVE it.
...Okay, yeah, they need a real job, this shit ain't working right. Not a lot of colleges that take divine mandate as proof of education, but beggars can't be choosers. Time to move. Again. Ah, see, that inconvenience right there is why they love Earth.
Most view Halcyon City as the birthplace of heroism, and one of the greatest cities of the East Coast. Mitou views Halcyon city as "the birthplace of thousands of vainglorious asshats who are desperate to control the narrative at every possible moment". Despite their reservations, Eclipse is Mitou's best bet at making something of their life on Earth, and proving... SOMETHING to Baphomet. Maybe they want attention, and are desperate for any form of notoriety. Maybe they're trying to create evidence that they hadn't made a colossal fuckup by their own choice. It could be a lot of things, but you sure as hell aren't getting a straight answer from their mouth.
