After being badly wounded by Elsa, Subaru somehow survived and awoke in the mansion of Margrave Mathers, in the Kingdom of Lugunica.

After being eaten alive by a herd of unknown creatures resembling rabbits, Subaru awakens in a half-maddened state next to Emilia in the graveyard. As he pounds his head against the rocky ground over and over in anguish, he finds himself invited once again to a witch’s tea party. There, he tells Echidna about his Return by Death ability, something he has never been able to tell anyone before. Echidna then begins to tell Subaru about the witch who gave him this power and set him on this agonizing path.
