Chrome

How Chrome joined the Tourney
From what her mother and stepfather talked about in a flashback, her original name was Nagi, and she lived an isolated and antisocial life. After trying to rescue a cat, she was badly injured in a car accident, which led to the loss of her right eye and some of her internal organs. The only way to save her life would be to have someone with the same blood type transfer their organs to her. She did not care whether she lived or not, and her mother refused to sacrifice her own organs anyway. However, Mukuro Rokudo heard her words and allowed her to live by creating illusionary organs.

In Hidden Bullet Novel: mono.CHROME, it was revealed that after recovering the wounds that she received from her accident, she immediately ran away from hospital and went to the neighbor town, Kokuyo as ordered by Mukuro. On her way there, she spotted Ken asleep on the nearby park. Seeing that he looked like he's going to die, she sits his head on her lap to make it comfortable for him to sleep. When he awoke, he was surprised, causing him to shout angrily at her until he feels hungry. Realizing this, she gave him an apple, which reminded Ken of his past when Mukuro also gave him an apple when he and Chikusa are hungry and ran away after eating the apple in tears. Unknowingly to him, she followed him all the way to Kokuyo Land, making Chikusa thought at first that she's an intruder. But when he found out that Ken knew her and eventually her connection with Mukuro, they let her stay in Kokuyo Land with them.

After the war in the future, Chrome found the Vongolas were being visited on by Minister Kuroda. He planned to make them his own privateer military force, but what Chrome suspects is that he is actually the leader of the Zodiac terrorist organization, Rasetsu.
