The 'Kobeni's Contract With The Sloppy Blowjob Devil' meme is a popular piece of 'headcanon' and shitposting within the Chainsaw Man fandom. In the series, Kobeni Higashiyama’s actual devil contract remains a closely guarded secret, leading fans to speculate wildly. This specific meme originated as a satirical and intentionally absurd theory on platforms like Reddit and 4chan, mocking the high-stakes world of the manga with low-brow humor. It typically features panels of Kobeni looking anxious or sweating—her signature look—paired with text identifying this non-existent, raunchy devil as the source of her powers. It has since become a staple of the 'Chainsaw Man Circlejerk' community, used to highlight the series' unpredictable nature and the fandom's penchant for surreal jokes.
