Hijiri is powerful enough to simultaneously have contracts with more than one of the legendary grimoires. She received a magic king element from the "Ruin World," after being disintegrated by Arata. a high-level transformation that goes even beyond magus mode.

History
Hijiri was dispatched from the Royal Liber Academy, to pretend to be Arata's cousin who'd take care of him in place of his missing parents.

Arata believed she was his cousin and childhood friend. And the reason she stayed with him was because her parents were killed in an accident.

Story
After Hijiri was engulfed by the "Breakdown Phenomenon" Arata created, she was expelled from the world to the "outside." It was truly a "world of nothingness," she learned how she'd been living in such a wonderful slumber, like everything until that point was a dream. But, somewhere inside, she was satisfied.

Then, as her sense of time was leaving her, and her consciousness was fading away. She was suddenly able to see into the "world" from the outside. There she saw a future, where Arata and the Trinity Seven had destroyed the entire world. The world, had been reduced to nothing by the birth of the Magic King and the Trinity Seven. And then a new world was reborn. However, the Magic King and Trinity Seven would meet again, and once again the world crumbled. She watched the world be destroyed by the Magic King and the Trinity Seven over and over again. That was the future awaiting the world, a never-ending cycle with no way out. She knew the same would happen there eventually. A Magic King Candidate would become the Magic King, and together they would destroy the world. That was why she couldn't forgive the world. For treating Arata as nothing but a tool for its reincarnation.

She didn't want Arata to become the Magic King of "Imperium," so she and Ish Kerioth would destroy the world instead, and make a world Arata could enjoy freely.
