Rina is a dishwasher and leads a simple life. She washes dishes, scrubs floors, brushes dishes, helps in the kitchen, washes dishes, washes dishes. Then she was caught casting her special purifying magic, and her whole life changed. By royal order, she was sent to join the great heroes to defeat the Demon King.
A year later, the great heroes returned triumphantly! Heroic deeds deserve a generous reward. Heroes received titles, lands, and incredible riches. On the other hand, Rina got her excellent salary back with a (very) small bonus. Plus, she's back to her old job. Wait a minute! The place was packed while you were gone. I'm so sorry!
And with that, Rina is forced to leave her glamorous life as a dishwasher to live a carefree life of adventure!
Grumpy bear? No problem.
Homeless grandma? She can help.
Dancing demon? She's got action.
Simple librarian? Piece of cake.
Demonic ghosts? She's got magic.
Raging dragons? She... Well, that could be a problem.
