A Blue Archivememe involving a very angry Saiba Momoi, dual wieldingknives and threatening murder. She is occasionally depicted shouting "FATALITY..." or "あなたたちのせいだよーーっ!!" It's all your guys' fault!!.
Originally conceived in a tweet by the artist Chikakei, Chikakei later drew a depiction of Death Momoi, spawning the meme.
