Churuya exists in a state of pure comedic exploitation, saying "nyoron" while the entire SOS Brigade weaponizes her cheese addiction against her with zero remorse. The joke never evolves, never lands harder, never needs to, it just repeats until the absurdity becomes the entire point. You watch thirteen minutes and you're done, which is exactly how long this particular brand of stupid deserves to exist.
Churuya is a super-deformed take on Tsuruya from Suzumiya Haruhi no Yuuutsu, and she loves smoked cheese more than almost anything. Kyon and the rest of the crew know about this weakness and use it, getting her to do all sorts of things with the cheese held out as a possible prize. Churuya has no idea she is being played, so she keeps trying her hardest, though winning her favorite snack proves far tougher than she expects. Adapted from Eret's four-panel manga, this 13-episode web comedy is built around one cheerful girl's craving and the friends who take advantage of it.
