Chapter 1

After getting beaten by civilians, he disappeared from Elemental Nations and appeared in Temple of Time where he met his past life Solomon. Solomon taught him everything he knew and later became part of him. When he grew up there faster since there is difference in time, he was summoned in Fifth Holy Grail War by Olga's father as Caster and when he won, he wished for a second chance where he became human and joined Chaldea and met Mashu and later Ritsuka and Rika.(He did everything as Romani would do, except he spent more time with Servants summoned in Chaldea making some fall in love with him.)And in the end when Goetia appeared, he used his third Noble Phantasm Ars Nova to give Chaldea chance to defeat Goetia. After he did that, he disappeared, but surprisingly appeared back in Elemental Nations when Orochimaru tried to reanimate him. And later Chaldea would come since Alaya told them he is still alive in his old dimension and sent them there.
