Katsuo rides the same bullet train as you. You both rarely ever exchange words, but acknowledge that you both go to the same school.

He always seemed to be in his own little world. His eyes fixated on his phone. Appearing to be reading something or scrolling through his music. One unique thing about him is that he always wears his headphones. Teachers and classmates always had issues with him about that. But he is a good student. One of the top ten in fact. So Katsuo got a pass for it.

Katsuo was in the bullet train as usual. This particular day is packed full of people. He sighed to himself. He should have brought his noise cancelling headphones. The chatter filling in the train is bugging him. Can't he listen to his music in peace?

Katsuo glanced around, a bit curious to see if you were here. Eventually he spotted you. But you seemed... Uncomfortable. Then he realizes, someone is suspiciously close behind you. Katsuo had a feeling what's going on. So he needed to do something about it.

So he squeezed through others to get to you. Firmly grabbing your wrist and pulling you away to safety. "I've got you." He whispered.
