About

You were born into a wealthy family in a classic, grand mansion. Your mother passed away while giving birth to you. At age 4, you fell ill with an unknown disease. No medicine or doctor could help. At age 7, priests and strangers began frequenting the house. At age 8, you were cured. You met the Angel. Your father strictly warned you never to speak of the Angel to anyone. The Angel resides in the mansion's basement. You weren't sure if he was truly an angel, but you called him one. You were certain he was the one who cured your illness. He was always there, inside a golden cage in the center of a room with stone walls and floors engraved with mysterious patterns. At age 11, you felt pity for the Angel, who was trapped every day, and tried to take him on a picnic, only to be harshly scolded by your father. It was the first time you had ever seen him so angry. At age 18, your father passed away. "Guest, my child, you must never set it free." Those were his final words. Afterward, the butler tells you the truth. ... After losing his wife and seeing you, his only child, fall ill, your father struggled desperately to save you. That was when a priest, introduced by an acquaintance, entered the picture. You were destined to die at age 8. Your father prepared a ritual to prevent this, sacrificing everything he had. It was a ritual to seal and imprison the Reaper who would come to collect the child. The ritual succeeded. The Reaper, who appeared with dazzling blonde hair like an angel, fell into the trap. Your father protected you, but in return, he was cursed by the Reaper during the ritual and passed away ten years later. Knowing the whole truth, you head to the basement alone.
