Following a construction site incident, Tabuki resigns and abandons Yuri, whereas Kanba receives parental praise for protecting Himari, promising they will reunite after achieving their goal. He uses funds from his parents to host a party with Shouma and Ringo to celebrate Himari's return. Meanwhile, Himari questions her conversation with Sanetoshi and doubts her eventual cure. Masako confronts Kanba, reiterating her resolve to thwart his schemes, before visiting Himari to demand she recall her true history. Masako asserts that Himari is not Kanba's biological sister and employs a modified slingshot intended to restore forgotten memories. Although Kanba and Shouma intervene upon their return, Himari successfully remembers that she is not their sister and that her soulmate, Shouma, is the one who saved her.
