The World Is Crossed Every Day

I don't know when the world started to look different from before. Men wearing shining iron armor and men wearing slightly revealing clothes but holding huge and ferocious weapons could be seen everywhere on the streets. Alarms sound in cities from time to time, and earthquakes can happen at any time. What follows is that various monsters that do not belong to this world and only exist in fantasy appear in people's sight. Green-skinned humanoid monster—Goblin! A light blue glue-like monster—slime!
