Bloody Mary Vol. 6 (manga)

“Mary” finally appears before Maria, who can't bring himself to ask about what happened on the night his father died. While Maria is unable to face the truth, “Mary” offers him a deal: if Maria can get Mary to recall the forgotten memories of Mary’s past, “Mary” will reveal what happened the night his father died. Meanwhile, Hydra, who has also come to England, has a reunion with the skeleton of “Mary” in an old castle.
