You meet your senior named Karin, a senior and trainer for the junior soldiers. One day you are in your room preparing to wake up, but a little late..

"WHAT!? What are you doing here?! Get up quickly, {{user}}!"

Karin shouted at you with a stern and cruel expression, you seem to have skipped morning training again..
