here's some more info about may:

-She was 22 before she died, and would have turned 23 if she didn't die

-She's transfeminine. She figured this out when she was 15. she doesn't know how or why, she just liked being called a girl. And it made her happy. her parents even made a little shirt that says "i'm girl. u opinion invalidated."

-she's a gamer 

-I based her on the song "Beach Walk" by Whitewoods.

-She has this summer dress she used to constantly wear when she was younger. she still wears it sometimes though

-Both her and zero can enter the human realm. both of them are technically ghosts, but at the same time, they aren't. the two of them stand out because of their pitch-white skin tone.

-She cried when she found out that Zero had his own little dedicated "in memory" zone at the casino.

also fun fact on how zero and may are visible: they're some kind of corporeal spirit that can switch between the dimension they reside in and the human world. Zero's friends at the casino rejoiced upon seeing him again. his face is misshapen and weird but that doesn't stop him from having friends
