Funny - I didn't recognize this anime from the English name, and didn't recognize the scene, but when I then followed the link to check out the anime and read the description, I thought, "Huh... sounds sort of like Inou Battle wa."
It was only when I looked at the cast picture that I realized that's what it actually was.
I guess that means it's about time for a rewatch...
I have done that occasionally in the past; go back and rewatch a show after enough time has passed that I forgot most of it. I never watched this show, but have seen the clip of this scene kicking around the internet ever since because of Hayamin's performance.
