Blue Exorcist: Beyond the Snow Saga

青の祓魔師 雪ノ果篇

Rin and Yukio Okumura travel to Lake Towada in Aomori after Shura Kirigakure vanishes without warning. There they uncover her birthplace and the history that binds her to Shiro Fujimoto, their late adoptive father. Back at the Japan branch, Arch Knight Lightning opens his own investigation into the Illuminati, tracing every thread back to the catastrophic Blue Night. This fourth-season arc splits its focus between Shura's hidden fate and the conspiracy tightening around True Cross Academy.
