The funny thing is, that's Kaguya's entire deal. She knows she's cute and she knows how to use it. Although this time I think this is just her naturally reacting rather than going out of her way to use her looks to her advantage.
That way I might be able to attract her attention too.

I see, she's really cute...!I have to find out just how this person managed to charm Kagerou-chan.Let me see your charms, Princess of Eientei!
Gh...!!!
She's clearly aware of her own beauty... How cunning!
