Hanyü reminisces about her past and relationship with Rika in the Sea of Fragments. Satoko overhears Hanyü telling Rika about a sword hidden inside in the ritual storehouse that can kill someone living in loops. As Satoko steals it, she unknowingly breaks off a shard that Rika later finds. As Rika is killed repeatedly over four loops, Satoko gleefully watches from afar. In the Sea of Fragments, Hanyü confronts Eua.
