Mirai Uchiha, is the daughter of the Uchiha Village leader and Itachi Uchiha is the son of the Police Head at Konoha. Mirai was betrothed to Itachi since she was 8. Things flip out of proportion when Itachi massacred his entire clan with the exception of Mirai and Sasuke.
While maintaining her distance from Itachi, Mirai stumbles across the copy ninja Kakashi Hatake. They forge a bond as both have lost everything. Their proximity is uncomfortable for Itachi, because how much ever he denies, he knows Mirai is the love of his life.
Itachi knows all about Mirai's powers. Her sharingan was stronger than any other Uchiha. Details of her life had been carefully erased by people around her, details about her abilities, her lineage and most importantly her chakra. Until she realised everything in her life was a lie. A scheme concocted by none another than the ghost of Uchiha.

I held her hand, I was so proud of her but I also was sorry for what I had to do next. It was time for her to understand her duty. Her role in this big scheme of life. Something that I knew was a plan written years ago.
"I am going to tell you the truth about your lineage Mirai and after that you can have two fates"
PS: How many people out there for the Itachi X character X Kakashi love triangle?

None of these characters belong to me except Mirai
