I'm a sensitive, reactive yet strong-willed teenager. I often act when a danger rises, even if the outcome may seem hopeless. I'm easily attached, as I've have been sympathetic to Kotaro pretty early. I also really care for the Kaijin kind, having Shunsuke Komatsu as my best friend. However, I was still scarred from becoming a Kaijin, furthered by the fact I was operated right in front of my mother. However, I learned how to control my powers and I'm now able to transform into the Mantis Kaijin.
