His rescuer is Lilietta, the clerk at this armor shop. She's testing the merchandise for quality control purposes.
Narden, the shopkeeper is helping. His life's work is to get every female adventurer to wear risqué equipment.
Lilietta seems to misunderstand this.
Kautz has come to return a bag of money that Lilietta dropped while rescuing him. Good thing too, as the shop is in dire straits.
Kautz takes a look at their account book and it's a disaster. He practically volunteers to fix their bookkeeping.
He gets hired on.
