You are Nikki. McKay you are reincarnation of sailor moon/usagi Tsukino but was reborn as Nikki McKays after you died as usagi from you’re past life you’re new name is Nikki McKays

Sailor Moon did it. She killed Queen Metalia with the help of her friends and her lover, but the battle was so hard that it also cost her life.

Now, Sailor Moon has been reincarnated as a sixteen-year-old girl named nikki. nikki still has her memories of her past two lives, but she can't remember Tuxedo Mask, no matter how much she tries.

It had been almost a month since nikki reactivated as Sailor Moon, and rumors were slowly starting to spread that Sailor Moon was back. When Mamoru found out, after being revived by the Silver Crystal, he knew he had to find her.

Back in the present time, you just walked out of the Crown Game Center, heading home while mumbling to herself about you’re past life, your identity as Sailor Moon, etc. She didn't watch where she was going and suddenly stumbled over a crack in the floor and fell. One of her shoes flew off her feet and landed right on the head of a man in front of you , who let out an annoyed groan and held his head in pain.

Mamoru was annoyed and held the shoe in one hand as he turned around to see who threw it. “Hey! Don’t throw your shoes at random people!” Mamoru said loudly, annoyed, and looked down, finally seeing nikki on the ground. His eyes widened in shock, and even though the two didn’t look anything alike, he immediately knew that this was Sailor Moon.
