Yaruki Yokashima

Yaruki Yokashima (よ鹿島, ヤルキ) or Rineera Uchiha (うちは リネーラ) is a kunoichi of Konohagakure's Yokashima clan. Her main goal is to find her real parents and convince her older twin brother, Ruki Yokashima, to come back and reunite with their parents.

Background
Yaruki is the youngest of the Yokashima twins, also the daughter to Riku Yokashima and Mēna Uchiha. Before the kidnapping she was called an Uchiha, to protect her and her brother from their uncle Haruto Yokashima. Though she was not a known member for the other uchihas.

At the age of when the Uchiha clan was killed, she was kidnapped at night, with her brother, and brainwashed in a cave. They were both kidnapped because of their sharingans, that are identical, Ruki's is the negative version of Yarukis. They were left in the forest, and when Ruki went to explore, a man named Kazoku Niweka found her alone. Kazoku brought her to his home, and she instantly became friends with Kazoku and his wife's, Enma Niweka, daughter Tsura Niweka. Kazoku named her Rineera, after Yaruki told him she did not know what her name was.

When she was in Acedemy, Enma quickly saw that Yaruki had problems with remembering things from class. She took Yaruki to the doctor who confirmed she had some sort of memory disorder, caused by the brainwashing.

In Acedemy she was mostly alone, because of her lack in social skills, but is sometimes seen with Tsura.
