Ga-Rei: Zero

After losing her mother, Kagura Tsuchimiya finds a home with the Isayama family and an older-sister figure in their daughter Yomi. The two work with a government unit that fights spiritual threats hidden from ordinary people, sharing both dangerous assignments and the comfort of daily companionship.

Family responsibilities and conflicts gradually place that bond under strain. As hostile spirits and human choices bring new suffering, the girls face dangers that cannot be overcome by skill alone. What is at risk is not only their survival, but the trust that has made each a refuge for the other.
