In Spirit Hunter: Death Mark II, Kazuo Yashiki is back in H City to investigate supernatural occurrences at Konoehara Academy. As in previous games in the series, the developers have drawn on Japanese myths and folklore to create an immersive and nuanced tale of terror. Some old faces return to aid Yashiki in his quest, and a 2D side-scrolling mode offers a new way to explore locations.
