Chapter 1 - Reborn with the eternal mangyeko sharingan

My name is Liam am your average person I work at the banker am a single guy and my life is relatively peaceful I get a pretty good income from my job and I also enjoy my job also on my leisure time I usually watch this anime named Naruto it's one of my favorite ways to pass time I also get the merch from time to time my favorite character is itachi uchiha he was such an intresting character but one day it all changed I was just casually walking to my job place it is relatively close but then I saw a flash of light then boom I was in so much pain I couldn't think straight then darkness when I woke up I was in an unusual place with trees near a river I felt smaller and shorter than usual I am 35 years old so this is very strange to me I also felt a weird sensation in my eyes I went to check myself in the river but all I saw is a 6 years old kid staring back at me with black hair and red eyes with a strange pattern I remember this looks like those eyes from Naruto if I remember correctly this are called the sharingan but the problem is that the pattern of his eyes were not the three tomoe pattern do the sharingan but a combined pattern like the mangyeko sharingan? But the problem is that he had never seen this pattern of mangyeko sharingan in the Naruto series so has he been reborn in the Naruto world as an uchiha with the mangyeko sharingan?
