Micro Worlds, a world inside someone's soul. It is a world where the owner is treated as a God. However, many others also awaken this power, and they fight against each other. Micro World fights against another Micro World.
The war involves hundreds, thousands, millions, or even billions of lives.
It is an era where war is not fought in the real world but rather in the Micro World.
Gabriel, a reincarnator, reincarnates in this world and awakens his Micro World. While the others do their best to upgrade their world, he uses Mods to make his life easier.
