Tenzen Yanagi is an eccentric old man, who meets Yusei Fudo on a paddy wagon after Yusei gets caught by Sector Security and is being sent to the Facility. A cheery old man who is well-versed due to his many travels to foreign lands, Yanagi serves as one of Yusei's allies. In the English dub, Tanner and Blister commonly refer to him as "Grandpa". In the original, he calls Yusei "sonny".
