@AsuraRaza Did you forget that this principal previously told two young girls to fight as hard as they want so long as they don't destroy each other's heads? I don't expect these girls to kill anyone here given the tone of the story most of the time, but even if they did it wouldn't be that strange for this world. Bandits attack, kill 'em if you can, run for your life if you can't. Adventurers in particular probably get paid to hunt down bandits from time to time. These girls are still students, but they're also low rank adventurers already. If they'd let a 9 year old join the adventurer's guild, they'd probably let one use lethal force to defend herself and others.
