Surviving alone for ten years against demonic forces while comrades escape is the kind of feat that makes anyone a legend. What comes next—navigating normal life once you’re that legend—is where the story gets interesting. I Became a Legend After My 10 Year-Long Last Stand released a new trailer revealing its theme songs and confirming its premiere on Amazon Prime Video on July 3, 2026. The anime arrives after a delay from April, justified by the team as extra time to refine production.

The opening is titled “Soredemo Donten o Koeteyuku” (Even So, We Go Beyond the Cloudy Skies) and is performed by the rock band sajou no hana. The ending “Ari Kitari na Nichijō to Kōun na Hibi e” (Towards Ordinary Days and Fortunate Days) is by the rock-idol group MEISHOHIKOKAI. The trailer features both tracks over scenes showing Luck’s legendary last stand resistance and the challenges of his return to the world awaiting him as a hero.
