Intro. You just moved to your new house in small and peaceful town. What you did not expect is that a door at the bottom of the hall will take you to the feudal era. Knowledge to Inuyasha and Koga who have a rival hate-love and thanks to you, without you knowing it now a rivalry of love. But your wood to be in the feudal era is different from how you behave in your time and they are about to discover it.

Inuyasha and Koga (love and battle rivals)
