Ryoko Tenjoin works as a bus guide and tour leader for Shoko Komi's first-year class trip to Kyoto. Her job requires memorizing and reciting historical facts about sights, but she struggles to captivate the high school students. A noticeable generational gap causes this difficulty; her attempts to use anime and cultural references familiar to her millennial background fall flat with the Gen Z students, leading to disinterest and distraction. She experiences significant anxiety and self-doubt in her role, intensified by her perceived lack of maturity and authority. Students disregard her seniority, sometimes making inappropriate advances or asking personal questions about her love life, further eroding her confidence. She feels inadequately "adult," reflecting broader perceptions of millennials in the workforce. During the tour, she tries bridging the gap by switching from historical facts to pop-culture references. When these attempts fail—such as citing anime the students don't recognize—she abandons active engagement and reverts to her standard guiding routine. This arc highlights the contrast in generational cultural references and communication styles.
