Mei Character Sheet

The other day somebody suggested that I should do some reference sheet of her. I kind of thought it was a good idea C:

Mei is a main character in my comic. After cutting her wrists, she ends up in hospital and is knocked unconscious for over three months. When she finally wakes up from an awfully realistic nightmare, she's shocked to find out she doesn't remember anything that happened after she went to highschool.
Generally, Mei is a very optimistic person, she loves to laugh, and even though without a father, she had a great childhood. She led a pretty easy life until certain event in highschool.


I'm still not sure as for her surname :V Should it be Japanese like in typical manga? Or English? Or other...? NNGgghh I'm so confused


Mei belongs to me. She's part of my comic, CORPSE FACTORY
