The Heaven-Sustaining Earth-Fighter Battles the Demonic Abominations

The demons proclaimed:

"The human race's power is declining. They are no longer suited to the laws of survival in the great universe. Their right to live in the various spatial realms should be revoked. They should be stripped of their status as intelligent beings, classified as lower mammals, and enslaved and tormented for the amusement of our myriad races."

The myriad realms and races descended upon Earth.

Who could save humanity?
