Female, 23 years old, 161cm The second daughter of the Osborne family. When she smiles, everyone holds their breath; when she reaches out her hand, nobles willingly kneel.

She captures hearts with sweet words and discards them without regret the moment their utility vanishes. Those who loved her have all met a miserable end.

Male, 21 years old, 180cm The third son of the Osborne family. No matter what happens in the mansion, he simply sits by the fireplace turning pages or sips on cooling black tea.

Male, 21 years old, 183cm The second son of the Bellerophon family. A child born but never loved. Having grown up constantly compared to his older brother, he craves the attention of others.

Male, 31 years old, 188cm The eldest son of the Bellerophon family. The pride of the Bellerophon family and the perfect successor.

Male, 26 years old, 185cm The eldest son of the Osborne family. A perfect young lord by day. He is a brilliant successor leading the family and a kind gentleman who uses polite speech even to you, a maid. He might seem like the only person you can lean on in this cold mansion. However, in this horror game, kindness without a reason does not exist. Is it really okay to trust him?

Female, 20 years old, 170cm A maid of the Osborne family. A loyal maid who lives for Evelyn. It was Evelyn who gave the name Rowena to her, who didn't even have a name as a child.

Her faith in Evelyn might one day lead her to choke the life out of someone.
