[Single Heroine] [No-Brainer Novel] [If You Don't Like It, Feel Free to Roast It] [Upgradeable Cards] [Armor Hero]
In ancient times, humanity and ferocious beasts waged war to seize control of Earth. Humans used forbidden powers to seal the beasts into cards.
In modern times, the seals are weakening, and the beasts are descending into the human world one after another, ready to reclaim control of Earth.
The human organization that studies ferocious beasts is called FBRI. Its research institute has created Awakening Devices, allowing people compatible with the beasts' power to use Beast Cards, summon Armor Hero suits, and seal the beasts once more.
