Ana

She lives with her younger brother Cathim in a room in a public housing complex in the Mazandaran district. She is deeply in love with her brother, but she tries not to think about whether it is a familial love or a forbidden love. As an adept who spends most of her time in the labyrinth, she cherishes her rare daily life with him.
Her parents were both adepts, and they're said to have lost their lives in the labyrinth.

She's the protagonist of the ninth chapter.
