Kenzan Koide (1964-11 December 2005) was a Japanese MIA Colonel who took part in Director Kyohei Jingu's attempt to recover his stolen ¥10 billion from the Millennium Tower in Kabukicho, Tokyo on 11 December 2005. Kazuma Kiryu took down Jingu and his two colonels in a fistfight on the tower's helipad, and the colonels presumably died when Akira Nishikiyama blew up the top floors of the tower in a suicide bombing.
