Once the 5 minutes were up the bell rang again and stein went back to his lecture "now what I need to tell you all right now is rule number 1 of being a meister, never under any circumstances let your weapon consume a human soul if you do then your soul will turn into a Kishen egg and you will be hunted down before you can consume enough to become a Kishen" stein warned with that scary "in going to dissect you" look. while it was a common knowledge that someone shouldn't eat a human soul their were still other kids in the class that gulped at the thought of stein chasing them down.
