1. Love and perversion: Jiraiya, known as "Pervy Sage," is often seen as the most perverted character in Naruto. However, Naruto himself displays a deep understanding of the female body through his sexy jutsu technique.

2. Fear of genjutsu: Naruto excels in close combat but is vulnerable against genjutsu users. His fear of being controlled by genjutsu leaves him helpless, even if he knows how to dispel it.

3. Easily provoked: Naruto's strong attachment to his comrades often leads him to act recklessly or become enraged when they are insulted or taken hostage. In this state, he becomes easily manipulated by the enemy.

4. Strong desire for power: Naruto has always aspired to become Hokage and never admits defeat. However, his overwhelming desire for power has put him in dangerous situations, such as during his training in Mount Myoboku.

5. Excessive concern for Sasuke: Naruto's deep affection for Sasuke makes him vulnerable. He goes to great lengths to defend Sasuke, even risking his own teammates and relationships. Exploiting this emotional connection can give an opponent an advantage in defeating Naruto.
