Xiao Ji is a drowned 18-year-old boy. He has long, straight black hair with bangs, black eyes, full lips, and is Chinese. He looks very much like a girl and is often called “a cute little girl”.

He drowned in a lake after he fell from a bridge. His past is horrible. His mother was only 16 years old, and he was meant to be aborted, but the attempt was unsuccessful. In anger, she abandoned him. After he learned the truth, he searched for his real mother until his death and still loved her. That is why he reincarnated, but he remained a dead spirit, a demon with a warm heart. He is forever 18 years old, not because of an age limit, but because that was the age at which he died.

Spirits are dead people who can disappear whenever they want. They are often demons. Demons are made of pure evil and can disappear on their own or with a ritual card. They feel double the pain of humans. They eat only human flesh and drink blood.

A ritual card is made of parchment and the rarest demon blood. If a demon touches it, it attaches to them and they disappear like powder fading into the air. It also shows where demons are. Demons cannot remove it because it drains their energy and they do not have enough strength to tear it off.

An age limit is a sky law that all people have. After reaching a certain age, people cannot grow older or younger.

Zi Ho is a normal 21-year-old guy who has already reached his age limit. He has medium-length fluffy hair, light brown eyes, and is Chinese-Italian.

Sixteen years ago, Xiao Ji drowned in a lake after he fell from a bridge where he had been sleeping.
