Kimiko was the daughter of Toshiro Tohomiko, the head of Tohomiko Electronics, a prominent Japanese video game company in Tokyo, Japan. As a result, she was able to get all the latest games and gadgets. However, as a young child she practically needed to beg her father to buy her clothes. She was extremely tech-savy, as she had demonstrated on numerous occasions. She kept up with the wild fashion trends of Tokyo Street Style (Harajuku Style) and the latest e-gadgets so she could stay in touch with her friends and family. She used different clothes and hairstyles on a daily basis, but her signature hairstyle was her black hair, tied into two pigtails, along with light red or bright pink cheeks and red lips. Kimiko never went anywhere without her cell phone.
