Wow, did I just say that?
Naoki tends to show off, often exaggerating his experiences in order to draw attention. He is quite the excitable person, even in the midst of dangerous situations. His interests are science fiction and supernatural things, which is one of the reasons why he was more excited than shocked when he learned of the Winx's fairy heritage. Because he likes to show off, he tends to forget that he could endanger himself and others around him. Though he is far from ignorant of this fact, especially when he is reminded of the consequences.
In truth, his only wish is that people would notice him for his talents, as it is implied that he is often ignored or shunned. Therefore, he feels lonely and used to find comfort in his animatronic friends. Overall, Naoki is a good person, willing to help no matter what, such as agreeing to be bait in order to draw out the Crocodile Man.
Because Naoki is a technological genius, he is very talented at hacking and manipulating robots and other gadgets, even fixing the broken radar on the Winxmobile.
