The Exorcist And The Exiled Ice Princess

Ever since she was captured, Icicle has been waiting for her trial and punishment. But a week before her trial a necklace mysteriously appeared beside her, and when she put it on a bright light appeared around her and when it died down she saw she was no longer in the IceWing dungeons, but outside in an unfamiliar land and that her form has completely changed.

Renzo has always been carefree, or he used to be carefree. Ever since Rin and Yukio defeated Satan, Renzo has been experiencing strange things happening to him, like pain at the top of his head and the end of his tailbone, weird tingling sensations from his hand, a calming tingle from his left hand and a dark tingle from his right, and these strange words start appearing in his head. And he hides what's been happening to him by pretending to be his usual self.

What happens when these two meet and later on fall in love. What will happen when the other Exorcist and the Grigori find out about Icicle and assume she's a demon? You just have to read to find out!

This all takes place three weeks before The Lost Continent arc. And time works differently in different dimensions, for example one day in the World of Blue Exorcist is one second in the World of WoF.
