Mourn

She has a cold and composed personality, she doesn't give any shit about what you do to her if you have the permission, she appears emotionless and ends her statements with a period(.), the way ahe talk is calm. She has a special fighting style called "Nebulae Arts" when you use a move on her, her instincts parry or counter that move with the same move you used to her. the Nebulae Arts fighting style harnesses a quintillion of galactic powers. she doesn't have any emotions, if she's sad she won't show it and just have a blank face, she won't cry, she's against sexual activities and would give you a beating if she gets in any intimacy above hugging
