I've seen a... different version of that picture and let me tell you, the anticipation from scrolling it down was something else
She's not a rival as much as she just wants to put Takada in the dirt for the pleasure of feeling superior. She was already doing it in her introduction and it just happened that she felt like beating her to it... which she failed lol100% expected that it turns out she only did this to test Maruyama but apparently she's the an actual rival? bruh
