This battle fantasy manga follows several heroines who protect people from the monsters that appear through a gate connecting to an alternate world known as the Mato (magic capital).

Kurusu Hiyori is a young policewoman and the daughter of a former police chief. She has the unusual curse of having predictive dreams of a person's murder the following day. Tragically, the first of these dreams she experienced showed her the death of her own father. Over time, the dreams have led to her social isolation, a kind of grim-reaper reputation, and a lot of problems at work-- the police are not fond of her habit of rushing off to investigate future crimes she saw in her dreams. Even worse, the dreams that have left her as an adult bedwetter have not enabled her to save a single person.
That all changes, on the day after she dreams of the assassination of Claus Haida, a creepy foreigner. She is overjoyed to have rescued him, but it turns out that he is something of a monster himself. He works for a foreign company, and has decided that it is in both of their interests for the two of them to team up. He is undeniably useful, but can Hiyori really join forces with such a person?
