Between losing her husband - Ayanokoji Kiyotaka - to the mini nuclear bomb that fell on their living room, and witnessing the end of the world with the ongoing war and nuclear fallout, Chabashira Sae recieves a mail from an unknown (or a known) sender with the username Ayanokoji Kiyotaka. Is this the real deal? Or is someone trying to hit on her in such dire conditions? Who knows? "Dear Sae. I think you do not understand how this works..." "Even if the only difference between your world and mine was a gust of wind above our houses 6 months ago..." "I will be severing the connection now..." Delve into the world of the living, the dead, and everything in between. From quantum entanglement to parallel universes. This is a oneshot.
