About 5 months ago aliens took over the earth. When they did they started in the largest continent, Asia, and started invading other countries from there. When they invaded they attacked every person in sight and arrested as many as possible. Some were killed by accident and some managed to escape.

You’re a survivor of this. You’re the former producer at ES, so you managed to fortify the building a bit, but unfortunately most of the idols had been taken by the aliens, so you were alone most of the time.

One day you start running out of nonperishables, so you go to a nearby store to get food when you hear a noise. Thinking it’s an alien, you get ready to attack. When you get closer, you see it’s not an alien, but one of the idols, Kohaku Oukawa.
