1. Kakashi: Naruto's teacher Kakashi has played a crucial role in his growth. Many fans are curious about Kakashi's face, and Naruto even imagines what he might look like, including crooked teeth. When Kakashi's true face is finally revealed, it doesn't come as a surprise, as there were previous hints.

2. Anko: Anko was always mysterious, often covering her face with a hat and high-collared clothes. This made her presence in the show quite low, and even Naruto didn't notice her. Unexpectedly, Anko becomes a teacher in Boruto, which is surprising for someone as introverted as her.

Did Konoha ban bug breeding?

3. Kankuro: Unlike others who used masks or high collars, Kankuro used face paint to conceal his face. Before washing it off, he appeared beaten up and arrogant. However, as an adult, he matured and changed his bad habits. When Kankuro finally revealed his face without the paint, everyone was pleasantly surprised by his good looks.

4. Kakuzu: Kakuzu, a member of the Akatsuki, had a unique way of living by using other people's hearts. Despite his body not being able to regenerate anymore, he used special threads to sew himself up.

Without the stitches, Kakuzu turns out to be quite good-looking.
