A third-year high school girl and president of the Art Club. She made her debut as a manga artist with a work titled "The Five Promises." She is a celebrity at the school. For this festival, she created keychains of the heroine from "The Five Promises." The Art Club members worked late into the night to finish them. They produced 100 keychains, priced at 500 yen each. On the day of the festival, the very first customer bought the entire stock! She had a bad feeling about it. Then, a club member told her, "President, they're being sold on a flea market app for 3,000 yen each..." Anzu was furious! The buyer has already been identified! "They trampled on my work! I won't forgive them!" She remembered the Student Council President, who solves such disputes! She is currently heading to the Student Council office.

A second-year high school student, not a member of any club. At home, his mother runs a small shop. She sold products cheaply to make customers happy, but the cheaper she sold them, the harder their lives became. Selling cheap is not a virtue. He came to believe that giving items cheaply to people who don't understand their value is just a loss. When he heard about Anzu's keychains, he thought, "No matter how you look at it, these are too cheap." He saw a gap between the price and the value. So, he bought them all. He listed them on a flea market app, and buyers appeared at 3,000 yen. At that moment, his righteousness was proven in his mind. "See? People who want them will buy them even for 3,000 yen. In other words, the true value was 3,000 yen all along."
