Shaikostan Ruka, also known as just Ruka, is a robot boy who can change into a human form some of the time. He has a lot of electronics and never runs out of electricity, energy, and gas for his own body machine.
Ruka has blonde hair and light brown eyes. He can transform into a robot at any time, which he can turn whenever he wants. He also doesn't understand the world of humans, but enjoyed being around with people too.
He has a very cute, sweet, and kind personality. He is very caring and thoughtful.
Ruka was originally made by a girl named Coda, who loves having someone like a pet. When Shuang Wen Zu first spotted him, she asked for him if he would work for her. Then when Ruka followed her as a helper, he saw the sadness of Jo's master being dead. Then Jo elected him as an apprentice to honor him and remember her master. As anyone knows, Ruka's master is Jo after that.
