Shiratori Ritsu, the sole male at Kirihara Academy for Girls and its priest, protects the school from demons but finds his sanity tested by the arrival of a new student, the one-hundred-year-old vampire Mary Harker, and a call from the devil, questioning his purpose in life.
A strange VN. It felt like it had all of the elements necessary to tell a really compelling story, and decided to do something else instead.
Overall, the story left me wanting more exploration of topics it raised. Instead it hand waves them away for the sake of more horniness.
It's a shame that this is on Steam and not Amatsutsumi which is a far better...
