Konata is 142cm and probably 35-40kg
I would be able grab her by her neck, choke a bit in air, and throw her againist the wall using a single hand
She would not go PUE PUE ofter it!!!

I would flush her timote- shampoo in the toilet and make her watch
I would stomp on each of her CDs and make her watch as they break
I would rip a manga page here and there so that she doesnt throw them out but when she rereads she will suffer missing a page
I would steal her dads money so that he thinks konata robbed him to buy games and manga so that she gets punished, and I would buy ciggies for myself with it
I would get her phone and message Tsukasa to come right now and I would be mean to Tsukasa too

I would force Tsukasa to rip manga of Konata so that they both cry
I would force Tsukasa to break more CDs
I would force Tsukasa to play games of Konata on her account so that n00b Tsukasa destroys all her progress, then I would delete all accounts belonging to Konata and make Tsukasa uninstall her games, finally making her throw the monitor out the window
Both of them will cry and be terrorized!!!

Then I would force them to swap clothes with each other when Im looking, including panties
I would take their phones and take photos of them wearing nothing but panties separately and send it to all Tsukasas contacts showing off her crotch, same with Konata so that they lose friends
I would force them to take off their panties at last and hand them to me and I would sniff them when they look and put in my pocket to bring back home

I would make them kiss each other
Make them touch each others tits with their hands going through each others sleeves because it is more erotic and ask them to review each others tits
I would force them to chew on each others hair, I would get scissors and cut a bit of hair of each and force them to eat the hair of the other person
I would bring a razor and tell them that disobedience would result in facial scars and tell them to go naked

I could go on with the blue demon treatment
