A girl falls into a well and lands 500 years in the past with a half-demon who hates her guts. The show knows exactly what it's doing: it builds a romance by making them argue about everything while the world tries to kill them both. InuYasha stretches its premise thin across 167 episodes, but the running jokes and character dynamics stay sharp enough that you keep coming back, and by the time you're deep in it, you're genuinely invested in whether these two actually belong together.

Kagome Higurashi is an ordinary ninth grader until a demon drags her into the old well at her family's shrine and she lands 500 years in the past, in feudal Japan. Demons hunt her there for the Shikon Jewel, a small but immensely powerful sphere she carries without knowing it. She meets Inuyasha, a half-demon who wants the jewel so he can become a full demon. He mistakes her for Kikyou, a shrine maiden he resents, and dislikes her on sight, but the danger they share pushes him to help her. When the jewel shatters during a fight and its pieces scatter across the land, the two set out with new friends to recover the shards before they fall into the wrong hands. The long-running fantasy adventure mixes action with comedy and romance.
