Dorei-chan wa Taberaretai

"The Castle of Ashes". Thought to have a werewolf who brought about a curse dwelling in it, people avoid the castle, and offer a child named Pariah as a sacrifice to ward off the curse. Pariah accepts her fate, thinking that being eaten will help people, but winds up fired from her duty as a sacrifice due to not looking tasty enough...?! Source: KADOKAWA
