Saguru Hakuba

Saguru is another teenage detective, just like Shinichi Kudo and Heiji Hattori. However, he does a lot of his work in England, as well as Japan, and claims to have handled more cases than Heiji. In the Magic Kaito manga and 1412 anime franchise, his main goal is to capture the master thief, Kaitou Kid, but in the Magic Kaito anime specials franchise, Saguru's main goal is to capture the assassin, Spider and using Kaitou Kid as a bait.

As a detective, Saguru takes great interest in learning the culprit's motives, asking "How come you did that?" Saguru also pays a great deal of attention to time, carrying a pocket watch that only loses 0.001 seconds per year. In cases, Saguru tends to note the time to the second. He is even more extreme in his earliest appearances; he notes during the Adam's Smile painting heist that Kaitou Kid is a minute and 13.02 seconds late.
