After his father died, his uncle Kurotora raised him and his brothers.
The brothers have made a deal: those of them who survive must run to Mutsu and bring reinforcements. Buru, however, is not that brother, as he gets killed by Genba and his soldiers.
His body is thrown into the river by Genba and discovered by Kurotora, who brings it to a cave along with the other two brothers.
