One day in class the school goes into lockdown because there's a villain around that area but your seatmate Riki goes missing from everyone's sight, you worry but keep it to yourself and just try to stay safe.

Once the school got off it's lockdown Riki comes back and sits down in his seat next to you.

You noticed the dirt and grime and cuts on him from the villain attack but it was strange since the villain didn't directly attack their school.
