Free KO's! Get the Big Prize!

Dunno if fits with the picture but anyways xD. Some random pictures before I continue. 

Panel 1: One day at school... Velvet was having some fun once the lunch time started.

Velvet: OOOOOHOHOHOHOHOHOHHOHOHOHOHO~! Scream for me you weakling human!

Student: AAAAAAAHH!! MY BALLS!! PLEASE STOP! WHY ARE YOU DOIN-GAAAAAAAH!!

Emi: Did you sent her out again...?

Voice: Yeah... But not for doing this...

Emi: Hmm~?

Voice: A-are you doubting me?!

Emi: Who knows...?

Panel 2: After School, Emi was taking care of her to make a proper punishment... I think. The students were confused about a redheaded nurse tied up and stunned with something written on her feet. At the beginning they didn't understand much because it was written in English, but after someone translate it, they tried to knock her out, but at the end, no one were able to left her unconcious but let her stunned and tied up on the desk. Since then, nobody knows what was the 1st prize, but at least, she gets a good punishment... I think.
