"Mata, Nichijou!" is a fanmade continuation of Keiichi Arawi and KyoAni's original Nichijou Anime. Which recollects and adapts chapters and storybeats from the manga not seen in that original run, pulled from Volumes 812.

It's meant to serve as a theoretical pitch on what a 'Nichijou Season 2' could actually look like in 2026, attempting to synergize with the style of 2025's CITY The Animation and Arawi's current works.
