Soshite Akuma wa Seigi wo Kataru

Chesterhill Academy, an all-boys boarding school...
A school where the students are trained to be as proper as angels, where the students who behave are guaranteed success in life after graduation. A self-righteous new teacher, Taiga, arrives at the school. There, Taiga meets a devilish student named Luca. Their encounter will be the trigger for a murder in this "Garden of righteousness." The devil will shake Taiga's sense of justice...

A school suspense that questions what is good and what is evil!
