K1-B0 also known as Kiibo is a robot created by Professor Idabashi. He was created to be able to grow and learn like a normal human and takes great pride in being a robot while also being very self-conscious about being seen as lesser or less capable than a human. He is very stubborn and willing to go to extremes to achieve his goals. He has been rarely known to resort to violence when he loses his sense of restraint. He wants to make people smile and truly learn what it means to love.
