Sora no Kanata no!

A phenomenon known as "Time Loss" causes all life on Earth to become statues temporarily. During these events, only a select group of humans, called "Receivers," remain active and can observe the horrifying truth: otherworldly creatures are trying to invade the human world. During a tennis match, a first-year middle school student named Futaba Sorano and her friend encounter a fish-like monster falling from the sky. Around her, everyone turns to stone and is later transformed into monsters. While being pursued, a mysterious boy named Riu appears and informs Sorano that she and the other Receivers must use their newfound abilities to defend Earth from these invaders. Sorano and her allies begin their battle to protect the planet.
