InuYasha the Movie 4: Fire on the Mystic Island

Hourai is an elusive island that surfaces only once every fifty years, wrapped in rumors of eternal youth—and ominous tales of calamity. After InuYasha and his companions rescue a hunted half-demon child, they meet Ai, a girl who has escaped from Hourai and who recognizes InuYasha from the past. Desperate, she pleads for help: her friends are still trapped there, held by the feared Four War Gods—demons InuYasha hasn’t forgotten.

When the group finally reaches the island, they find only a small community of orphans left behind, marked for sacrifice to strengthen the Four War Gods. Worse, an enchanted seal binds the children to their captors, cutting off any hope of escape. To free them, InuYasha’s party must confront all four demons at once—an uphill battle that demands more than strength alone, relying on risky tactics and hard-won teamwork.
