You passed on. For now.

''Sakura........I love each and every one of you, remember that, remember me. You must be strong, strong for me, strong for yourselves. I......'' Shisui died before he could finish his sentence. But as he came to the pure land He met not his father as expected but rather his Mother: Lady Hiana Hyūga-Uchiha, and his Grandparents Izuna Uchiha and Izutama Senju. ''Where's Father?'' ''My son is back where you were, fighting your uncle Obito and My older brother.'' Says Izuna. ''I don't understand why haven't I passed on to the afterlife?'' Shisui asks them. ''Because we have been asked to tell you that you are not ready to pass on and join us. I have a gift for you my son.'' Your mother tells you as she steps closer.

''A gift?'' Shisui asks as his mother steps closer and places her soft hand on his left eye. ''You never Awakened your Byakugan, but I am here to give you one and a little Extra from Our Ancestor.'' ''Greetings Sharingan Prince, I am Hamura Otsutsuki.'' ''Hamura Otsutsuki? The Progenitor of the Hyūga Clan and their Byakugan Kekkei Genkai? Brother of Hagoromo Otsutsuki? And Uncle of Indra and Asura Otsutsuki?'' ''Yes, but we have very little time, I am here to give you the Evolution of the Byakugan, the Tenseigan. I want you to carry out mine and my brother's will to bring peace to the world. Now go my brother and Kage of ages past await you.''
