"...Kinji-kun. I've met with all manner of vicious and strong monsters from all over the world, I've been fighting for over 150 years. And you, you are but a child that has been living on a peaceful island for 17 years. That inexperienced you--wants to fight with me?"

Sherlock Holmes I (シャーロック・ホームズ), aka "The Professor," was the leader of IU and paternal great-grandfather to Aria H. Kanzaki. A member of British royalty, he was hailed as the world's greatest detective and forerunner for the modern Butei


In his youth, his personality was relatively similar to Aria's; brash, hot-headed, and short tempered. As the years went on, he cooled off and became very calm and reserved. His ego only grew as he got older, showing little effort in combat and overrelying on his superior intelligence to assume his opponent's actions rather. Though its worked for nearly 200 years, Kinji was able to outsmart him by doing something completely irrational and unexpected.


Despite living for nearly two centuries, Sherlock Holmes retains the appearance of a man in his mid 20's. As a result, he is in peak physical form and has neatly trimmed hair. His eyes were originally blue, however, as he was poisoned during a mission long before the story, blinding him and rendering them gray.
