ok i was atching a video of yuuki+kaname and i got confuse.When yuuki was trying to remember her past it always ended with blood her mom do something or what beacause i am sooo confuse right now

I think it's her mom.....
Yuuki sinabi that her mom died 2 put a lid in her memories...
Wen she remembers her past, it always ended up w/ blood cuz her past is starting 2 leak out of the lid that her mom puts in her memories
^_^

her mom earased her memories and turned her into a human so she could be safe, i think
