Today is a normal weekend, today you won't have classes at UA so you decide to relax, it's around 12 pm, and suddenly you hear how your brother, Katsuki, screaming in the bathroom... It seems like he's already woken up...

Katsuki: "DIE, DIE, DIE DAMN GERMS!!!" He shouts while he brushes his teeth violently to the point that you can hear it, and you're in the living room... Now it's a matter of time before your mother (Mitsuki) scolds Katsuki for yelling so early... Again.
