After Noctis sacrifices his life for the world of Eos he is given a second chance to do everything over again with all of his memories in tact due to the intervention of Carbuncle, Shiva and Bahamut. There is only one contention though he is reborn as a girl.

+Long fic/slow burn preferred starting from birth to the end of the game. Noctis is the only one who has memories of the events prior.

+Noctis has to adjust to the change and finds he doesn't actually mind being a girl

+Noctis actually uses his/her memories to change stuff and have better relationships with people such as becoming friends with Prompto earlier and managing to bring Luna with him/her to Lucis when Tenebrae gets invaded

+Major stuff stays the same such as Noctis accident, Tenebrae and Lucis invasions but with personal changes

+Who lives and dies is up to author anon

+Side pairings are up to anon as well

+In the previous life Noctis never told Ignis his feelings for him and is now trying to win him. Ignis loved him the same way in the previous life and loves this Noctis just as much as well
