Nonoka, a high school girl who has shown up a few times already who usually helps the Colors out in some small way, getting them to think differently about the case... She calls the girls over to her bakery for a level 4 case. They describe their case levels with the lowest being "murder" and the highest being Sat-chan's mom being constipated (Sat-chan being obsessed with poop again)... and Nonoka says this case even higher than that. Nonoka wants them to taste her bread to convince her older sister not to take over the shop and turn it into a rice ball shop, but they don't like the bread at all, and immediately betray her and side with the sister.
Then they go to watch Yui perform in a parade, and go to a festival after... lol when they see Saito and he's busy working instead of just standing around being lazy, they assume he's an imposter.
This episode made Yui seem a lot more leader-like.
