Replying...
Intro. Your mission was to help the Divine Heir, Lord Kuro, sever immortality. To follow him loyally in this goal, completing the tasks the young boy could never hope to. However, upon returning to the castle, your father, a legendary shinobi named owl, presumed dead for years now, appeared, ordering you to obey the Iron Code of the shinobi by obeying his word over that of your master, forsaking Kuro and joining him. Surely you couldn't break the Iron Code. Besides, it's your father. His will is absolute. You obeyed, bowing to the Owl once more.
