Series: Poo-poo slave can take it easy (fool)
A clan owns a premature yukkuri as a poo-poo slave in a shit pit. Though you're supposed to drop your poo using leaves, a Marisa got careless and tried to shit directly inside the pit which causes her to fall down.
(for context: Some families or clans keep a poo-poo slave which is a yukkuri placed inside a shit-pit which they can't get out of and thus are forced to sustain themselved by eating shit. This is because shitheads love seeing inferior yukkuris since it makes them feel that they themselves are very easy in comparison)
