Kamitoki no Resist

A red spell binds Hayato and Jin as they face the legacy of the Jinkishi, the guardian who seals demons in the Capital. When the Jinkishi dies, his magic disappears, and Hayato travels from Tokyo to claim the vacant position. The power belongs by inheritance to the Shihoudou family, but Jin, its possessor, has no interest in becoming the Jinkishi. As the story unfolds, Hayato and Jin become bound together by a spell of fate, a connection described as thicker than blood and deeper than destiny.
