InuYasha the Movie 4: Fire on the Mystic Island

犬夜叉 紅蓮の蓬莱島

Ai, a young half-demon, flees Hōrai Island and crosses paths with Inuyasha, who once stood on that same island fifty years earlier. Drawn back with Kagome, Miroku, Sango, and Shippō, Inuyasha finds the half-demon children there held under the rule of the Four War Gods — Ryūra, Jūra, Kyōra, and Gōra. This fourth InuYasha feature film sends the group to free the island and forces Inuyasha to face the marks the War Gods left on him long ago.
