(That second one was drawn using a base, I don't know who made said base tho :P)

Name: Shadow (No last name given)

Age: 20

Gender: Female

Personality: Quiet but a salty little prick, more talkative around her friends

Crush: She doesn't really care, but if pushed, she'll say Cuphead just to get the person to go away.

Backstory: Ran away from home after an incident with her inner demon and her mom clawed up her eye, used to be good friends with Cuphead and Mugman when they were children, has had the ink illness for years and somehow miraculously survived considering the severity of her condition

Other: She does have a sister who she occasionally talks to once in a lunar eclipse so they both know that the other isn't dead but her sister doesn't have much impact on the story
But, if you're curious...

Her name is Kara Hellborne.
