O, Hero! When Kazuya Souma is unexpectedly transported to another world, he knows the people expect a hero. But Souma's idea of heroism is more practical than most—he wants to rebuild the flagging economy of the new land he's found himself in! Betrothed to the princess and abruptly planted on the throne, this realist hero must gather talented people to help him get the country back on its feet—not through war, or adventure, but with administrative reform!

Set five years after the mysterious disaster of a city's sudden disappearance, a group of girls fascinated by the "Theatrical Material System" using 3D holograms aims to brighten the stage during the city's post-apocalyptic recovery.

It, a mysterious immortal being, is sent to the Earth with no emotions nor identity. However, It is able to take the shape of those around that have a strong impetus. At first, It is a sphere. Then, It imitates the form of a rock. As the temperature drops and snow falls atop the moss, It inherits the moss. When an injured, lone wolf comes limping by and lays down to die, It takes on the form of the animal. Finally, It gains consciousness and begins to traverse the empty tundra until It meets a boy. The boy lives alone in a ghost town, which the adults abandoned long ago in search of the paradise said to exist far beyond the endless sea of white tundra. However, their efforts were for naught, and now the boy is in a critical state. Acquiring the form of the boy, It sets off on a never-ending journey, in search of new experiences, places, and people.
