Teruaki is Nariyuki's father and a teacher known for his genuine ability to connect with students. He made a real impression on Nariyuki by recognizing his struggles as a learner and using that as a teaching moment rather than a weakness. Teruaki consistently emphasized that effort matters more than natural talent, and he believed that people who've had to work hard for their understanding can better empathize with others facing similar challenges. He basically shaped Nariyuki's whole approach to learning and perseverance by modeling that mindset himself.
