Ep. 6: The girls settle into Yumiko's boathouse while Kazuki confirms her identity and Thanatos offers help.

The group arrives at Yumiko’s mobile boathouse, which she owns for its strategic hiding capabilities. Inside a facility, Yuuji verifies the hologram is Kazuki, who reveals Oslo smuggled a nuclear bomb with a 50-kilometer blast radius. She explains Yuuji’s value as the sole survivor of lethal human enhancement experiments that killed subjects within two years. Meanwhile, Michiru receives a call from Kazuki on Yuuji’s phone, leading to an introduction by Thanatos, who offers assistance to rescue Yuuji and disrupt Oslo. Despite doubts, the girls agree to cooperate, though Amane finds the voice familiar. The next day, Kazuki distributes untraceable cellphones and convinces Yumiko to confess her feelings for Yuuji to test her resolve. Later, Kazuki explains the truth behind the bus accident years ago where Amane escaped while she remained behind.
