I Got the Full-Time Mage System but I'm in Naruto

When he woke up and found himself in the world of Naruto, Nobuhito Namikaze said that he was panicked. Fortunately, he also has a system plug-in that is necessary for time travellers, but there seems to be an error in this system. [Almighty full-time mage system], he is in the world of Naruto, shouldn't he be given a ninja system? Also, why does Mao have to show off before he can use it? Who doesn't know that he is a low-key and humble person? However, after using it, Nobuhito Namikaze could only say two words, it smells great! A few years later, facing the pretentious Uchiha Dance King, Namikaze Nobuhito defeated him with one move. "In the ninja world, no one is allowed to be more pretentious than me!"
