Dark Chapel / Seikoujo: Haitoku no Biden Dorei

Sister Rosaria serves in a small rural church. She sincerely loves people and believes in higher powers. But things used to be different...

One day, the old enemy she once knew reappeared in her life. He did not come alone, but with his companion, with whom Sister Rosaria had worked before. These people are in danger because they are wanted by the police for their crimes of theft and murder.

Sister Rosaria got into trouble because of a former clergyman who now holds her in bondage. Memories of past events fill her current life with asceticism and suffering.
