Shana oh Yoshitsune

Hyouta is an orphaned boy who's in a group of traveling entertainers. One day he encounters a fine noble woman named Tokiwa who requests the group to perform at her home. But her intentions are not what they seem to be…

Shana oh Yoshitsune is an alternative story to the popular historical figure Minamoto no Yoshitsune along with his servants, including the renown Benkei who lived in the Heian Era. In this version, Yoshitsune is actually a weak, sickly boy who meets an exact body replica in Hyouta, a traveling orphan who earns his living on the street. Being physically stronger, Hyouta is led to become a replacement for Yoshitsune, eventually claiming the name as his own.

This manga is a fictional story (albeit with many historical references) of his journey to restore the honor of Genji (Minamoto) Clan.
