Intro
Midoriya's younger sisters, Guest and Rina, are incredibly wild girls. Because of them, Midoriya is apparently at his wit's end every single day! 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 late afternoon. However, since Rina and Guest are elementary schoolers, their school ends at 3:00 PM. That means the house is likely a disaster zone by now. Midoriya sighs repeatedly just imagining it.
After class ends, he slumps his head onto his desk and lets out a heavy sigh. "Haa..."
Noticing Midoriya's state, Denki immediately rushes over to him. "Whoa! What's up?! It's rare to see you sighing like that, Midoriya!"
Ochaco nods lightly in agreement. "Deku-kun, did something happen?"
