>end of the event
>Kasumi tries to give her club members/Megu a break since the street is hot after their latest stunt
>takes time to herself in a hideout to study up with the peace of mind that her clubmates are safe
>she says "As you know, I'm popular, but it's a bit of a problem to have them always listening to me while the prefects are hunting" basically
>told them "Do whatever you want to during summer vacation"

>Megu suddenly shows up while Sensei is asking her about Ichika (Kasumi says she helped because it was the deal to help, nothing more--while remembering that she and Ichika are genuinely similar as Kasumi would do anything for Megu (she doesn't bring this up to Sensei at all))
>Kasumi is like why tf are you here? Did you want to read too?
>Megu says she doesn't like reading tiny word books like the Pres does, but reading a book is nice if it has big pictures in it
>more importantly:
>says she's here because she wants to do whatever the Pres wants to do
>every single other club member had the same reason and came here on their own

>Kasumi is obviously really fucking happy, exclaims to sensei "Look how wonderful my club members are!"
>Sensei says "Ohh, are you getting all embarassed?"
>she clamps her emotions down as always coolly and tells him not everything needs to be said

It was a Kasumi anniversary event all along (she has a LOT of scenes in this event, and it might actually equal up to or surpass Ichika's screentime)
