From Aki Irie the creator of 'Ran and the Gray World".

Unbeknownst to Kei, his little brother Michitaka has a dark power and an even darker history. Freyja has gone into hiding to escape him, but Kei helps Sigrún track her down—exposing her to potential danger. Meanwhile, a mysterious detective is hot on Michitaka's trail...
Against this backdrop of tension and fear, Kei continues to explore the stark beauty of Iceland, though nothing in his new surroundings could be starker or more beautiful than Lilja. As their mutual antagonism reaches new heights, could something else be developing between them?
