Death: Travel a Hundred Years Ago and I Was Your Eldest Cousin?

I have traveled through time and space to the Soul Society a hundred years ago. At this time, Urahara Kisuke has not yet become the captain, but what does that have to do with me? In great anxiety, Hayamahiko still chose to become a Shinigami, but the Zanpakutō is actually called the Book of the End. Does this mean he wants me to be his eldest cousin? Ichimaru Gin: Rangiku, have you forgotten the persimmons I gave you by the Daming Lake? Rangiku Matsumoto: I don't understand what you are talking about. The person who gave me the persimmons is clearly Ayan. Also, don't come to me all the time. I'm afraid Ayan will misunderstand. … Kuchiki Byakuya: Hijin, marry me! Kuchiki Hijin: Ayan, I really don't know this person, believe me! … Unohana Retsu: Come on, Ayan, let me help you become the strongest Kenpachi! Zaraki Kenpachi: Then shall I go?
