  • Junko Takeuchi asks Yuko Sanpei about her first impression of Boruto. Sanpei says that the biggest feeling was that he was Naruto’s son, so at first she wondered at what points to make him like Naruto (referring to when she’s playing him), but she ending up only thinking about Naruto. She had to try to play it while intentionally not looking at the Naruto series up until now. She had to think more about the relation between Boruto and Naruto.
  • Junko Takeuchi then asks to compare Boruto at his rebellious age to themselves at their own rebellious age. Takeuchi admits that hers was pretty close to Boruto’s, while Yuko Sanpei says she was pretty much a good kid. Takeuchi said that when she was a kid, she wished that her father had used a more gentle voice with her at the time. She says she was more like Boruto than Naruto, and called her younger self “a not-so-cute brat". Therefore she wants to dedicate this movie to her father.
  • (For the Boruto anime) "The BORUTO TV anime. It’s a dream come true. What will happen in the world Boruto’s father, Naruto, made in the previous generation? What will they do? The mission at Three Man Cell, the happy family... There’s so much I want to see. I hope to go on exciting adventures with Boruto, Sarada, Mitsuki and the rest of the gang in my work. I hope you enjoy BORUTO as much as you did NARUTO! Watch me be awesome!".
