Overview

常識改変 (joushiki kaihen) means "changing common sense," often referring to altering or shifting common sense, norms, or conventional wisdom.

This tag is often used in erotic works that aim to transport the audience into a fictional world where societal norms and common sense are completely altered. By doing this, the creators can push the boundaries of what is considered acceptable or normal, leading to provocative and stimulating content. This allows for the exploration of taboo or unconventional themes.
