All 3 volumes are now available from Earth Star Naru! Thank you very much! Kazue Koyoshima (45 years old) is a school lunch lady. I was transferred to another world in my daughter's middle school uniform. They say it's a hero summoning. --- Isn't this something for young people? Isn't there an age limit? I thought. Five heroes were summoned. Everyone else is young, so I thought I would leave the battle against the demon king to them, but wait? Could it be that I've become young again? I'm back to my middle school body! But, being a hero is a bit much, right? No way, no way. ...But it turns out that in middle school, I was so small that I wasn't counted as a combatant! "How old do you look?" "--- About ten years old... I'm sorry." I even get an apology from a handsome knight. But since those who do not work do not eat, I think I'll be a school lunch lady at the royal castle. Leave the omelet rice and pudding to me! ◆◆◆ [Completed on 2021.12.31] Thank you to everyone who has supported me!
