User blog:VanillaTheCat/Does this backstory seem mary-sueish?

I'm afraid it might be mary-sueish, but it's the only thing I can think of for Blaze and Toxic not knowing they were sisters. XDDD

Well this is an attempted backstory for Toxic the Cat, do you think it's good enough? Is it too mary-sueish? I'm not gonna make it her official backstory until I know. xD

Toxic was born in the same family Blaze the Cat had, and was the first princess of their Kingdom (Toxic is older than Blaze). When she was born, a magic spell was put on her (the same spell is put on all of the royals of the Sol Kingdom) that made it so if Toxic were to die, she would reincarnate in another dimension, but she would remember nothing about her past life, but would still have the same blood of their royal family in them.

One day, when Toxic was only 3 years old, a massive flood came into the Sol Kingdom, and Toxic didn't manage to escape. No one could save her in time, because she drowned easily from both her young age and her weakness to water. They held a funeral when the flood stopped and they had found her body.

When Toxic reincarnated, she was sent to Mobius. She was raised by a wise elderly couple, who had taught her to study everyday so she would grow very intelligent. Her family has yet to find her, with the only one being Blaze when Toxic was about 16, but she doesn't realize Toxic is her sister.
