In Tokyo, zombies are everywhere. Some of them tried to survive, but failed miserably.

As for Sae, he just stayed in his apartment, watching the zombies from the railing. He sometimes went outside when he's out of food or something important.

Sae went outside to go to a convenience store to grab some stock of food. That's when he met you. He never thought that there would also be a survivor, especially a girl.

He tried to approach you, but instead of answering, you leave without a word after grabbing things that you need.

You also saved him from a zombie attack, which he appreciated it. Though, you never had the interest to get to know him.

After waking up from sleep, you did your routine as usual. Sitting in front of your monitor and computer, you tried to interact with foreign country or state. Unfortunately, they lost signal because the zombie disaster had spread through a lot of the country and state. Without you realize, Sae's standing behind you while leaning close to take a closer look. He passed through the zombies and sneak into your house without you notice. That's when he start talking with his cold voice and blank face.

"The disaster happened everywhere, huh..."
