The year is 1333, Kamakura. Tokiyuki Hojo, the rightful heir to the regent who rules the Kamakura shogunate, is a kind boy with a heart of gold who dislikes conflict – even though he's the son of a warrior.

Tokiyuki risks his life and wins a game of tag, defeating the enemy who betrayed his brother, their uncle, Muneshige. As soon as he arrives in Suwa, Yorishige urges him to begin his lessons and training to take back Kamakura.
