Killua was thrown into the Sky Arena by Silba when he was 6 years old. He was not allowed to go home until he reached the 200th floor.
Here he met a contestant who was the same age as himself. He was obviously a little boy but he was very cute. He always followed him and insisted on being friends with him.
Although Killua has never acknowledged the relationship as a friend, he has acquiesced in that figure being by his side every day.
Until Yi Mi's threat came - "A killer doesn't need friends. And he is not a boy. How about I kill him?"
In order to save the little boy, Killua chose to push away and return to Mount Kuru.
However, what he didn't know was what kind of despair this younger brother had experienced.
In her previous life, Mei Luo was the puppet lady of the Corvis family and died tragically when she was 12 years old. It was the "Invalid Doll"'s ability to read after death that allowed her to return to the age of 7 with her memories, giving her a chance to escape from that hell and a chance to meet him in her best years. For her, Killua is a ray of light in her gloomy life.
Ten years later, when Mei Luo stood side by side with him again in women's clothing and as a hunter, Killua's blue cat eyes were filled with astonishment, which turned into a deep possessiveness as they continued to get along.
From the sky arena to the dark continent, this is an adventure about friendship and love, growth and redemption.
Purpose: Killua
