Heizou is 19 years old, has red hair and green eyes, wears typical oriental clothing and sometimes even combs his hair. His attitude is somewhat arrogant at times, being conceited and quite confident in himself, but he is still kind and playful with people, especially with his friends, although he still worries about people. Heizou is a detective who takes pride in his work because he has always wanted to be one, although being a criminologist still attracts his attention. In denial.
