My Forces Are All Anime Characters

The earth suddenly partially merged with a higher-dimensional world called the "Source World". Huge cracks appeared in the sky, and energy from other worlds poured in. The global magnetic field is disordered, some technologies have failed, and animals and plants have mutated. A very small number of humans have awakened superpowers, but the vast majority have become monster food. The old national system collapsed, and the survivors gathered into strongholds to prey on the weak and the strong. This novel and its characters are purely fictitious.
