Kazuo Saitoh, voiced by Hiroki Takahashi, is a 17-year-old senior in high school. Born on July 18, 1981, he has blood type O and stands at 181 cm (5'11") tall, weighing 72 kg (159 lbs). He resides in Tokyo and enjoys reading manga, building plastic models like Gundam, and playing video games.
Despite being the youngest team member, Kazuo is notably tall. As the only son of the Saitoh household, he assists in running a small electronics store. Tragically, he lost both parents at a very young age but maintains a carefree and energetic demeanor. Initially considered irritating by Nakajyo and Mishiba, they eventually grow fond of him. However, his lack of physical strength often makes him a burden during fights.
Nonetheless, Kazuo excels with electronics and machines and is adept at solving puzzles and memory problems. His favorite foods are hamburgers and spaghetti. Additionally, he works as a convenience store clerk at his school.
