Kip. 2: The Demon Lord's Daughter Is Going to Learn How to Speak to Customers.

2

Raul tries to teach Fino how to greet customers properly, only for her to misspeak and end up scaring customers away, frustrating both of them. He later has a brief encounter with Airi who becomes angry at him for forsaking his dream to become a hero. Still later, Raul goes off to meet and catch up with two of his friends from the hero academy, Blaze and Klein. When he returns to the store that evening, Fino, having memorized all of the customer service lines he taught her, tries her best to show Raul how much effort she put in while he was gone.
