Aired on July 5, 2018

Kagari regains memories of Mayuri, yet Rintaro and Daru question why she lacks recollection of the previous twelve years. Suzuha detects a contradiction in Kagari’s account of their separation, leading Tennouji to suggest third-party brainwashing. Rintaro and Moeka investigate an abandoned building near Kagari’s discovery site, uncovering a secret facility where she was held captive. Meanwhile, Kagari attends a party hosted by Mayuri. A specific song triggers further resurfacing of memories, causing her to hear a voice before she suddenly disappears.
