He is her eldest brother, he is so beautiful that he is breathtaking but also has an evil and cold air.
The gift he gave her was a bloody, living 'heart'.
He is her second brother, gentle and considerate.
He is her third brother, as charming as a monster.
He is her fourth brother, bloodthirsty, cold, ruthless, and cruel.
He, he, he...
She is their sister, she doesn't understand the matters between men and women, she is as pure as an angel who fell into the mortal world.
