Flashforward
A recording of Ai Hoshino, holding the twins while they're still a baby, wishing for them to grow healthy and well.

Summary
The internet reacted to Ai's death with sympathy, but there are still some who uses it to gain attention, either by reacting coldly or using it as some kind of criticism towards the government. Ruby rages at the heartless comments.

After just three days, the story stopped being brought up as news cycle takes place, and the kids were officially brought up to become Miyako's children.

Later on, Aqua came to an epiphany. His mother's information shouldn't have leaked easily, unless she herself leaked it to their potential father, who are possibly also a figure in the entertainment world. He then resolves himself to track him down, and kill him with his own hands. Aqua then meet up with Taishi Gotanda, and ask the director to raise him up as his kid.

More than a decade pass, and the curtain raise up for the next act of the story, as the twins are now entering high school for the first time, and Aqua's revenge tragedy began.
