Monster Strike the Movie: Sora no Kanata

Thirteen years prior, a mysterious phenomenon caused a section of Tokyo to detach and ascend into the sky, resulting in a division between "Old Tokyo," the airborne fragment, and "New Tokyo," which remained grounded. This extraordinary event severed all communication and interaction between the two realms, leaving their inhabitants to adapt to their new realities over time.

Amidst the looming threat of Old Tokyo's descent back to the earth, a determined young girl embarks on a daring journey. Her mission is to traverse the treacherous path from Old Tokyo to New Tokyo, driven by the urgent need to protect the citizens from the impending disaster. As she navigates this perilous adventure, she encounters formidable challenges and uncovers the secrets of both worlds, all while racing against time to avert catastrophe.
