I like it a lot, love the personalities you gave the mains although they do seem a tad like "archetypal" slice of life characters.

Midnight's the sane one, the one who has to deal with everyone else's weirdness. It'd be pretty cool if he had a weird side underneath, though. Scarlet's the pervy slacker type who usually ends up getting beaten up. Crimson's the strong one; probably quieter than the others, but dedicated to physical prowess.

Looking forward to more of this. I can't see the mains the same way anymore now...
