In Normal Ending 2, Wadanohara sacrifices herself to become the new Cast Pearl, returning the sea to peace but losing her life in the process. The townfolk mourn her passing, being one of the beloved residents of the town, but Samekichi is stricken by grief the hardest. He laments that he couldn't save her and that the sea has no point if she isn't in it, and it's heavily implied that he ends up taking his own life so he could be with her again. The sea is safe, but at what cost?
In the True Ending, Samekichi sacrifices himself instead, to punish Sal on all what he had done and return everything to normal with the Sea of Death destroyed. Wadanohara blames herself for his disappearance and believes herself to be weak, finally breaking down in front of Fukami after hiding her emotional pain behind a smile for so long. She vows to become a better witch so Samekichi will be proud of her.
Doubling as a Heartwarming Moment, the moment when Wadanohara finally gets to meet her father('s spirit). Though he may already be gone, he'll always be with her.
