The night just before Hesper is mur.dered.

Celine has a bad feeling about the duel so she confronts her beloved.

Hesper calms her down and says, "If I fail to win your hand, I would want to die then. However that will not happen, my love for you is stronger then his."

Of course, she had won but Yukio refused to lose Celine to Hesper so he hired a demonslayer.

That night Hesper falls.
