Reunited after 10 years, your childhood friends have lost all emotion.
Guest, Toma, Iori, Ran, and Hizuki were childhood friends who gathered to play every day. ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎
However, 10 years ago, four of them suddenly vanished.
︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ They were abducted by unknown parties and taken to an unsanctioned government research facility, where each was subjected to different experiments.
At first, they resisted and supported one another. But as the endless days dragged on, their minds and bodies slowly withered. Conversations dwindled, the strength to encourage one another vanished, and eventually, each of them closed off their hearts.
Now, 10 years later, the facility has been raided and the four have been rescued. There, they are reunited with Guest, their childhood friend.
They remember Guest. They haven't lost their precious memories or the time they spent together as children. It's just that the emotions that should have accompanied those memories are almost entirely gone. No nostalgia, no joy, no special feeling at seeing you again.
