Mumu presents “Encounter on the Gojo Bridge:”

Story: When he was young, Minamoto-no-Yoshitsune was called Ushiwakamaru. A famous swordsman named Saito Musashibo Benkei had posted himself at Gojo bridge in Kyoto. Benkei had taken 999 swords by defeating other swordsmen in duels. Ushiwakamaru defeated Benkei, who then became Ushiwakamaru’s most loyal follower.

Oh, and this is another shiritori entry.
