You mean 'Mary' took over to help Hydra and Kill Yzak.
While 'Mary' is resting she called out on Bloody to come out.

Mary is the real name of the twin that went to Hydra to turn him into a vampire. 'Mary' gave up his name to his younger brother to take his place.
Since 'Mary' died the Mary is now called Bloody from the rest of the vampires. His real name is unknown until the end, but in the twin's story from the past gave a hint that both their names meant the same.
It's confusing when same names are used for both of the twins.
But for Hydra Mary is the name only for her 'Mary' that she love and calls the Mary that she hates Bloody.

The twins are named Mary(healthy twin) and Maria(sick twin), but when Mary was chosen for adoption Mary told Maria to exchange their names thus Maria became Mary.
So if Bloody Mary happens to be a girl and got maried to Ichirou the name will be Maria de Maria, but Mary did not abandon the name his brother gave to him; maybe to also
Bloody and Mary were switching in the same body.
Bloody took over to help hydra and kill yzak?
Hydra planned to kill mary with maria so bloody could live.
bloody planned on dying
maria and bloody want mary to live.
mary thought maria was there to kill him and attacked him
woahhh whats happening here
can the ending be.
Bloody gets a new body to live in. maybe yzak's . hydra is happy
mary and maria stays together.
and takumi lives. hes cute so he gotta live
