Shymalan releases a recorded TV announcement, saying that he intends to wreck genocide on Japan to weed out the weak. The government, though slow, has begun to take steps to contain the Ryunka that is beginning to spread throughout the Greater Tokyo Area. Tsutomu, though advised not to go out of his house, decides to do so and save Sayaka. Nejula suggests that a faction of the Federation Police may have not decided to quickly respond to see the power of Ryunka. Muroto decides to help Tsutomu after he finds out that the ship is the Lost Bird, where Sayaka is held. Shymalan is killed when the Ryunka inside of Sayaka is activated, with a segment of the Japanese public. Birdy, meanwhile, is moving in on her own to stop the Lost Bird from moving any further.

Birdy meets up with her childhood friend, Nataru, and they talk for a bit. They are interrupted by a girl in a wheelchair, who treats Birdy coldly. A second of the criminals is tracked down, and she pursues him for a bit, but he escapes only to be killed in a violent manner Birdy is not familiar with.

Senkawa and the journalism club go investigate a refugee camp. While Hayasumi is just trying to get a good story, Birdy is hoping to get a lead on another alien living in the camp. Two young children, Takumi and Marina, give the club a tour of the camp. They run away into the ruins so that they don't have to be separated, but get attacked by a group of thugs. Nataru, volunteering at the camp, goes after the children, but isn't strong enough on his own. Birdy arrives to rescue him.

Continuing the memory dive, Tsutomu learns more of the Central Tower attack and Birdy's part within it.

Nataru and Moss fight but Moss is nearly killed before being rescued by Birdy who attempts to convince Nataru to surrender and receive treatment before his Iksiola state kills him. He refuses and nearly kills Birdy before Senkawa switches in and convinces Nataru that being an Iksiola means more than just killing. Nataru relents and jumps back in time to the moment of the tower attack becoming the man who saves a young Birdy via a time-loop.
