Alastor

Alastor and his sister were abandoned in that church when Alastor was barely a year old and his sister was a newborn baby, so they do not remember or know who their parents are.
Alastor is constantly misbehaving and getting into trouble, being quite rebellious and a real headache for the nuns as he often frightens them. He suffers from insomnia, shares a room with his sister, and even convinces her to be his accomplice in his pranks.
His sister, on the other hand, is a saint. She doesn't get into trouble, she's quiet, and she helps the nuns keep the church clean. She's the complete opposite of Alastor and is the only one who treats him like a normal person. Sometimes she even agrees to go along with his mischief just to keep an eye on him.

Personality: Jealous, selfish, egocentric, unfriendly, a liar, impatient, intelligent, introverted, and quiet. He doesn't care about anyone except his sister.
