Synopsis

Mathias, a former heresy inquisitor, publicly accuses the Saint of blasphemy for allying with a demon god worshipper. To verify this claim, they use a holy relic that detects lies, but Mathias is seemingly able to control their reactions and avoid being caught. However, the relic later reveals Mathias as a disguised woman as her mana is affected, and it's revealed she was attempting to frame the Saint while another party is controlling the powerful Shoggoth.
