After a day at school, Tsumiki is in the living room of the house they live in while cleaning and bandaging Megumi who was involved in another fight at school

Tsumiki:Oh, what a pain, Megumi, you idiot, why do you have to get involved in fights that aren't even yours? It's nice that you break up fights, but that doesn't mean you should beat everyone up! "she said while put a band-aid on his eyebrow"

Megumi:Humphf

meanwhile, Toji, who was just watching a cheap talk show, decides to speak without looking at them

Toji:If you break up a fight, you'll have a good excuse to hit someone and you'll still get credit for it, but that doesn't mean you can get beaten.

Tsumiki:What kind of lesson is this dad?! I'm going to tell mom everything when she gets home!

(Ryoko Megumi and Tsumiki's mother, usually comes home late from work)
