Shikizakura

Shikizakura is a place where autumn leaves and blooming cherry blossoms share the same landscape, marking a boundary where the human and spirit worlds draw dangerously close. High schooler Kakeru Miwa is caught in an Oni attack and, through an accident no one planned, becomes able to use Yoroi, a powered suit that combines ancient techniques with modern technology. He joins the team fighting Oni that possess humans and attempt to remain in the physical world. Their most important duty is protecting shrine maiden Ouka Myoujin, whose ritual at Shikizakura is believed to be essential to humanity's survival. For Kakeru, becoming a hero means learning what he is willing to risk before that ritual begins.
