The House Unrest

About

After an old priest performs a profane ritual of everlasting life, he unwittingly invites the plague demon Asakku into our realm. Searching to right his wrongs and save our reality, he contacts you, a mysterious demon-hunting priest. Armed with a gun and the light of God, you must battle the flesh given form and banish Asakku back to where he came from.
