I Got a Cheat Skill in Another World and Became Unrivaled in The Real World, Too (Special) - The Legendary Dragon—Awakens

The special slots into the timeline of the parent series between the end of the school-year arc and the start of the second-year campaign. The Legendary Dragon — referenced obliquely in two episodes of the original season — is the central guest. Yuuya, his familiar Night, and the household supporting cast travel into the deeper layer of the magical continent his late grandfather's notes indicated. The film expands on the school-friends back in Japan and the connecting fabric between the two worlds, and arrives at a confrontation that the rest of the series will be allowed to continue without.
