Kengo Yozakura is the third son and the fifth sibling of the Yozakura Family's 10th generation.
Kengo took his spy license exam when he was 7 years old. When he took the exam he also did it as two other people, leading him to have three licenses. This was borderline against the rules, and he returned the licenses soon after he received them.
