Multiverse: Getting Sharingan at the start.

This is a story of Akira, A young man of the age of 24.After his grand father died,He work as a cashier on a Mall until he found something strange in his laptop. .... ..... ( Note: this is just a fanfiction of many animes and other stuff, they have their own writers. I don't own anything accept oc. And the main point is this is just a wish fulfilment story) ............. Those who don't like harem stuff pls don't watch it because it will be harem but not much. ( And the cover pic is also not mine, it was taken from solo levelling. So if the honourable creator want to remove it just write an comment.)
