Memory Brandon

From Kokorodatabase

Memory Brandon was a member of The Black Soul, supposedly the incarnation of the sin Pride in her timeline. It was she who created Kyr's former hatred for Ichigo, as she twisted the dynamics of the Shirogane family in order to gain access to the secrets of the Mew Project (and indirectly, the secrets of the Shirogane family). Kyr foiled her last year, killing her in battle. Everything she had created became undone, and the timelines restored themselves, as Memory no longer existed.

In terms of her true origins, Memory originally hailed from Chrono Mew Mew, having been born in the year 2000.

(Eh, this is a stub. I'll probably edit it more if it's really needed.)
