Peace after the war is merely a cover for a cruel exchange plan. Trials of Interspecies Sisters ~Erotic Exchange with Humans~ is where non-human nuns are pushed into human territory. They are nuns of various species brought under the guise of cultural exchange.
Instead of mutual understanding, these pure souls are forced into a path of corruption with no escape. All the faith they had previously forged is put to the test. Gradually, they become corrupted. Selfish desires begin to replace their thoughts. They surrender their bodies to actions that betray their own beliefs. Yet now, this pleasure is what they long for.
