"...I leave Her Highness... in your hads."
"Nekone, live on... and find happiness."
With these final words, Oshtor's soul finally found peace... leaving Haku entrusted with his sister and the princess. For the sake of his friends, and to fulfill his promise, Haku casts aside the name he was given... and dons his fallen friend's mask, choosing to live on as Oshtor.
Armed with his wits and the power of Oshtor's name, Haku faces a battle more dire than any before. Nekone steels herself to support Haku through whatever comes, suppressing the pain of her brother's death. Thrier friends mourn the loss of two dear comrades: Haku, who they believe dead, and Kuon, who left them for her homeland.
It is here, on the cusp of a new conflict, where we return to this land. The flames of war are about to consume Ennakamuy... and soon, all of Yamato.
