WorldEnd: What are you doing at the end of the world? Are you busy? Will you save us?, often referred to as SukaSuka, was released in 2017 as a television anime adaptation of the light novel series written by Akira Kareno and illustrated by ue. Produced by studios Satelight and C2C, the series was created during a period when the post-apocalyptic fantasy genre was seeing a resurgence in Japanese light novels. The production aimed to capture the melancholic and philosophical tone of the source material, which centers on the remnants of humanity struggling to survive against mysterious beasts in a world of floating islands.

The design of the series is noted for its ethereal visual style and emotional weight, reflecting the character-focused narrative that defines Kareno's writing. Under the direction of Jun'ichi Wada, the adaptation was received as a poignant departure from more conventional high-octane fantasy shows of the era. Critics and viewers often highlight the series for its deliberate pacing and its exploration of themes regarding legacy, sacrifice, and the inevitability of loss, solidifying its place as a distinct entry in the studio’s portfolio of speculative fiction.
