Izuku Comes Back At Chaldea. ( Izuku X Morgan Le Fay. )

( P.S. All Of The Main Singularities, Pseudo-Singularities, As Well As Lostbelts Have Already Been Completed By Izuku. )

When Izuku Yagi was 4, he was diagnosed as Quirkless and after he was, his parents, the Pro Heroes, All Might and Green Tempest, began neglecting him and his twin sister and his now former childhood friends began bullying him and beating him up everyday. When Izuku was 15, he was attacked by a villain with a Quirk that allows them to randomly teleport someone someplace and was randomly teleported to Chaldea, where along with learning that he had mage ancestry, he also helped resolve all of the main singularities, all of the pseudo singularities, and also all of The Lostbelts as well. He also fell in love with 4 different female servants, all of whom who also fell in love with him as well. However, Izuku only ended up dating 3 of them, with those 3 servants not letting the other servant date Izuku, which upset the other servant, Morgan Le Fay.

However, just after Izuku completed The Lostbelts, those 3 servants cheated on him with someone in an event singularity and because of that, Izuku decided to suddenly leave Chaldea, only leaving a short note saying goodbye. Because of this, those 3 servants were de-summoned and Morgan locked herself in Izuku's old room at Chaldea.

Thankfully, after 3 years, Izuku, who went back to Japan to go to UA after leaving Chaldea, where he actually awoke a Quirk, decided to come back to Chaldea after he graduated from UA, partly after Chaldea's new director asked him to come back to Chaldea as it's first ever own Pro Hero, however, mainly after he was told about how Morgan was still depressed that he'd left, with her actually still keeping herself locked in Izuku's old room at Chaldea. Izuku also won't be coming back to Chaldea by himself as he'll be bringing his 2 adopted daughters along with him.
