Yui comes across as a dedicated teacher who genuinely cares about her students' wellbeing. She's strict about enforcing school rules and won't hesitate to call out misbehavior, but it's clear she does this because she wants them to succeed and feel good about being at school. Despite the stern exterior, her real goal is always to help.
That said, she's got a playful side that catches people off guard. In the game, Yui loosens up considerably—she's cheerful and acts almost like a teenager herself, which throws some people off. What's notable is that this laid-back personality doesn't undermine her wisdom; if anything, it makes her better at connecting with young people. She genuinely understands them and knows how to approach their problems in constructive, positive ways.
