Yuito explains Kasane possesses gravikinesis, not psychokinesis, and that the Kunad Gate exists because of their connected powers. He claims his death will close the gate but urges Kasane to kill his past self to trigger her Red Strings. Witnessing his death, Kasane returns to her time and finds the dying Chairman Sumeragi, who confirms the New Himukan government turned Naomi into an Other.

They discover ampules similar to those used on Naomi and encounter Others. Naomi briefly regains human sapience to communicate with Kasane before reverting to an Other state.

He realizes the medicine is derived from psionic blood and brains. After a brief skirmish, Arashi allows the team to escape, acknowledging their moral doubts. Naomi, having overheard the scientists, rejects the drug due to its high cost and requests time alone.

To escape lunar radiation, survivors diverted the comet’s energy to Earth, forming the Extinction Belt, forcing Kagero to stay behind. After escaping OSF forces through a cavern, the platoons battle an adapted Other. Kagero then explains that Togetsu was established by immigrants seeking to return to the Moon, utilizing cryogenic monitoring and Design Children like Kasane, who possesses Red Strings to control time.

Fubuki reveals he was childhood friends with Karen, Luka, and Alice, who sought to join the OSF despite lacking psionic abilities.

Kagero reveals his own familial loss, explaining that Togetsu’s success would erase their time together. Yuito accepts the truth as the platoons prepare to infiltrate Togetsu. They note Yuito’s exponentially increased power, a sign of fading abilities due to brain damage from Karen’s forced connection to Arahabaki.

Nov 18, 2021Yuito and Kasane share a final breakfast with their mother before tackling the dimensional entanglements keeping the Kunad Gate open. They enter the Chronos Terminal, where red strings intersect, to manually untangle these connections at three distinct points: the day Others attacked Suoh, a dark future involving an older Yuito, and a date where they find Karen. Upon returning to the present, they discover the gate remains open because Wakana’s presence in the current timeline is the final entanglement. To resolve this, Wakana returns to her own time and uploads her brain into BABE's database. Before leaving, she expresses her pride in her family, concluding their mission to stabilize the timeline.

Kagero doubts this because Yakumo had a child before dying, but notes access to the Sumeragi Mausoleum is required to verify the claim. Yuito visits his brother Kaito, who has been stripped of his OSF authority. Kaito intends to kill Yuito for his brain, but Yuito mentions their mother and his goal to protect New Himuka. A swarm of Others attacks, and Kaito fights them to allow Yuito to escape, giving him the mausoleum key.

To find answers, Yuito and Kasane lead their platoons into the Sumeragi Mausoleum, which is filled with illusions from Karen's past. Despite suffering from psionic backlash caused by these illusions, the groups successfully reach the casket of Yakumo Sumeragi. Inside, they discover that Karen is still alive.

Dec 9, 2021Karen reveals he traveled two thousand years back to absorb Yakumo Sumeragi’s power to save Alice, repeating this cycle across alternate selves. Present Karen, who copied Yuito and Kasane’s abilities, confronts his past self at the Sumeragi Mausoleum and forcibly absorbs his powers, gaining a connection to Arahabaki. This transfer forces him to relive the memories of everyone linked to Arahabaki, including his past iterations. Yuito and Kasane show him Alice’s fondest memory: her desire to become strong for him. Despite this, Karen remains determined to let the Kunad Gate destroy the world to save her.
