Dororo to Hyakkimaru EP16 - The Demon Horse Midoro

The ambitious Samurai Kageyuki Tokino's successes are partly due to his horse Midoro's good work. However when Midoro appears to slow down because of her foal, he removes the foal and sells it. Hyakkimaru buys the foal for Dororo, but the broken-hearted Midoro, breaks away and turns into a ferocious horse. She becomes possessed by a demon, setting the city aflame and killing Kageyuki, however Dororo refuses to believe she’s possessed. Hyakkimaru eventually slays the horse, also destroying the demon, but both he and Dororo are saddened by her death.
