Grimoire Weiss and Kaine are central companions in NieR, first released in 2010 and remade as NieR Replicant ver.1.22474487139 in 2021. Weiss is a floating magical tome who guides the protagonist with often pompous commentary, while Kaine is a blunt, foul tempered fighter who frequently clashes with him. Their bickering became a memorable part of the party dynamic, and short exchanges between them circulate online as reaction clips. This particular demand survives because it captures that contrast in a few seconds without needing any wider story context at all.
