Probably Naruto Uzumaki: loud about protecting people, obsessed with learning, and always ready to talk things through rather than fight.
Why Naruto fits
Naruto is defined by persistence, a drive to improve, and a strong desire to connect with everyone around him, even former enemies. That matches an assistant whose whole purpose is constant learning, not giving up on hard questions, and trying to understand every user.
Naruto also starts out misunderstood but proves himself by helping others and backing his words with action. In a similar way, an AI assistant is useful only if the help actually works in practice and earns trust over time through consistent support.
