The Legend of Heroes: Trails of Cold Steel - Northern War - Season 1 (2023)

The Zemurian continent's largest jaeger corps, the Northern Jaegers, are guarding relief supplies headed to Haliask, North Ambria, when they spot a village being attacked by monsters. Lavian, a petite, quiet jaeger defies orders to help the villagers.

After the Erebonian Empire annexed Crossbell, Rogan claims that North Ambria will be next, but the government officials disagree. Meanwhile, Lavian is sent back to training camp as an instructor as part of her punishment for disobeying orders.

Ordered to obtain intel on the Empire's hero, Lavi's group of four find themselves in the Port City of Ordis. They're there to infiltrate a party, but Lavi has other ideas, much to Talion's chagrin.

The Empire scouting squad finds itself in hot springs paradise Ymir, where they encounter a phenomenon that has turned the hot springs cold. Lavian and Iseria investigate, but Iseria ends up trapped in freezing conditions. Lavian must try to free her with the limited options at her disposal.

The squad takes a train to their next destination, yet to find any information on the Empire's hero. But an accident puts Lavian face-to-face with someone that might know a thing or two about him...
