This is the FIRST [1] VOLUME of the Omamori Himari (My Guardian Himari) fanfic. Did you find yourself in the world of a harem “ecchi” manga? Oh, it seems that the dream has come true, and you can relax! Only in a few years they will try to kill you. And eat it. Knowledge of how to protect oneself is catastrophically lacking, and clan “power” is rather, um, specific. And between you and the crowd of hungry demons is a protective cat moving at full speed. You can try to stupidly follow the canon - with unclear prospects at the end. Or you can try to sort out the “dowry”. In the end, the scientific approach, even in magic, has not been canceled.
