The story centers on an introverted high school student named Eiji Hoshimiya who has a huge secret — he wished for the destruction of the world when he was younger. After the disaster happens, certain people acquire special powers called Orders, and what Order Users can do with their power depends on their wishes. 10 years after the Great Destruction, Eiji struggles to come to terms with his immense power.

10 years ago, the world was suddenly brought to ruin by The Great Destruction, and ever since then Orders, people capable of wielding super powers, have appeared. Hoshimiya Eiji is one such Order--and the very cause of The Great Destruction!

Hoshimiya Eiji is forced the truth--The Great Destruction was caused by his sister, Sena, and to protect her, he stole her powers and rewrote her memories. With Sena helping him, Gennai begins to open the Gate. The Group of Ten rushes to the scene to face him in the final showdown, but can they stop him in time to prevent another Great Destruction? With Sena's life and happiness at sake, what choice will Eiji make?!
