She then starts to seduce Yuto until Himari, wearing a cat costume, stops her. Later on, Himari tries out another katana from Noihara's waepon vault but is dissatisfied until Kuesu arrives with her damaged Yasutsuna, in which Ageha has Sasa repair it with her eye beam.

Shizuku and Kaya later appear and reveals to them about Shuten-doji and Tama's origins and their agendas. At night, Yuto tells the girls that he still wants humans and ayakashi to coexist and proclaims he will fight Shuten-doji and Tama for that cause. At the park, Kaburagi meets with Shuten-doji and Tama, who agrees to Kaburagi's deal not to harm any humans during their plans. Late at night, Himari sets off for Shuten-doji and Tama only to find Yuto blocking her path. After he tells her that they have to stick together, Himari embraces him in tears and, just when they were about to kiss each other, Kuesu interrupts them with the other girls following suit which later leads to a series of misunderstandings.
