After being swallowed by the Varugas, Gareki is saved by the serendipitous appearance of Eva. While Eva escorts Gareki away, Nai, Yogi and Akari visit Nai's former home. Meanwhile, Eliška reveals to Uro that she wanted Nai to be captured as a surprise for Karoku. After searching the home, Nai, Yogi and Akari find an old notebook full of calculations hidden behind the wall. Following a picnic by the shore, Gareki receives permission by Hirato to visit his hometown Karasuna. Nai, Gareki and Yogi all go to Karasuna, as they meet acquaintances of Gareki from two years ago. Tsubame is guilty of murder and has blackout episodes, but her twin brother Yotaka is oblivious to this. Gareki explains to Nai and Yogi that his parents sold him off to a cargo ship at eight years old, and he was later saved and raised by Tsubaki when she was alive. At night, Nai, Gareki and Yogi spot Tsubame sneaking outside. The three run outside, only to find a dead man marked with scars. They then turn around and see Yotaka with blood on his hands.
