Here's the beautiful redesign of Alice's older sister. This is the 5'3ft demon sadist drawn by @hamdynobody this is Uchi Kanojo the heated rival of Alice.

All of her rage towards her little sister comes from her own shortcomings from not gaining any of the demon goddess abilities. She hates Alice since she was the choice to be the demon queen throne but Alice is a weak willed failure that doesn't wanna rule. Uchi with all her hatred tortured Alice along with her other sisters to force her break but Alice's will was ironclad. It wasn't until Uchi helped plot an opportunity for her sister's escape so all the focus could be on her. The plan was a success and with Alice out of the picture Uchi wanted to prove herself but going alone into the over world to raid towns to collect beings to be turned into food.

With her raids she gained a reputation through her sadistic tortures she puts her victims thought before she decides to figure out what she will do to them.
