Miyoshi Yoshimune

Yoshimune Miyoshi is the main character in the Durarara!! 3 way standoff game and manga. He is often called by Yoshiyoshi by his friends and other characters in the game.
His handle name is Eight in the chat room, and Hachidaime (Eighth Successor) in the Dollars. Two of these nicknames come from his old school because his first name, Yoshimune, sounds similar to a Shogun of Japan, Tokugawa Yoshimune.
