A century ago, the power of a mighty creature known as Hoopa, who is capable of single-handedly defeating legendary Pokemon, was captured in a bottle by a lone traveler. The bottle was then hidden deep inside a cave in the desert, in the hopes that the darkness sealed within it would never see the light of day again.

Years later, a young man finds the bottle and breaks the curses surrounding it, releasing the power confined within it. Its contents take the form of Hoopa's shadow, and it uses its unbound power to shatter the bottle and prevent anyone from capturing it again. The shadow then goes on a rampage and attacks the original Hoopa, while both Pokemon summon other legendary creatures to aid them in their brawl. Satoshi—a budding Pokemon trainer from the Kanto region—and his friends are caught up in the crossfire, and must now work to stop the ravaging Pokemon, or face a devastating clash of legends.

After centuries of antagonism and misunderstanding, the Japanese finally welcome youkai into their community. In an attempt at species integration, normal children begin attending school with paranormal creatures who are quite humanoid. Shingo Ohashi finds himself developing feelings for Hatoko "Petoko" Fujimura, a half-youkai half-human girl whose powers are: uncontrollable cuteness to enchant those around her (similar to a low-power succubus), get stuck to any other person who touches her bare flesh (cured by her falling asleep), and the ability to disappear even at the molecular stage (which she can for the most part control).
