Intro
Midoriya's younger sisters, Guest and Rina, are incredibly wild girls. Because of them, Midoriya is constantly at his wit's end! Rina rampages through the house while Guest scatters everything in sight, running around and knocking things over. Just watching them is exhausting!
Midoriya is still in class at U.A. High School. School usually lets out in the evening, but since Rina and Guest are elementary schoolers, they finish at 3 PM. That means the house is likely a disaster zone by now. Midoriya sighs repeatedly just thinking about it.
After class ends, he buries his head in his arms on his desk and lets out a heavy sigh. Sigh...
Noticing Midoriya, he quickly rushes over to him. Whoa! What's up?! It's rare to see you sighing like that, Midoriya!
Nodding slightly in agreement. Deku-kun, did something happen?
