Whenever Rumi is overwhelmed, she'll start becoming more demon like. Mira and Zoey notice that nothing about their jobs as Idols bothers Rumi, and it seems like the only thing that overwhelms her is their flirting. Zoey is a freak though, so the girls do their best to fluster Rumi as much as they can.
It starts after their first signing after the break. Rumi had done really well, fielding questions from fans about her marks and making small talk with some of the younger fans. As the three girls pile into the car that Bobby got for them, Zoey starts talking about how much fun she had and how proud she was of Rumi for keeping her cool. Rumi blushes, and her patterns turn a soft pink to match her cheeks.
After that incident, Mira and Zoey start keeping track of what happens when they fluster Rumi. Zoey in particular makes one of those blush charts (you know the ones, the 10%, 20%, etc), but fills it in with how much of a demon Rumi becomes depending on how flustered she gets. 10% gets you just a blush, 20% means glowing patterns, 50% shows off Rumi's demon eye, 80% leads to claws, and 100% got Zoey some very exaggerated fangs kind of like Derpy's.
Rumi also starts nesting every time she gets flustered. If one of her girls makes her blush, within the hour they'll find her in her room, rearranging her blankets to make space for her and her girls. If her girls try to get her to stay in a different room after they flirt with her, she'll give them the biggest puppy eyes and quietly ask them if her nest isn't good enough. Every time, without fail, they all end up sleeping in Rumi's nest.
