Albedo chasing Clementine with an army of janky CG goblins is the show admitting it knows exactly how ridiculous this premise is, and it commits completely. The comedy lives in that gap between godlike power and actual incompetence, between Ainz's perfect control and his subordinates solving problems by throwing bodies at them. This is a side story that doesn't try to matter, which is why it actually does.
Brought back to life, Clementine now hides as a fugitive, trying to get out of the Kingdom before Ainz can catch her again. Luck is not on her side, and she keeps crossing paths with the battle maids. Meanwhile Albedo sets out to hunt her down, backed by Aura, Mare and an absurdly oversized army of CG goblins, ready to wipe out anything that blocks the way. Clementine was once one of the Zurrernorn's twelve disciples and the ninth seat of the Black Scripture. The result is a three-episode comedic fantasy ONA with action to spare.
