In typical troublesome fashion, Naruto sets a trap for their very tardy Jounin teacher, but Sasuke is not convinced that such a teacher could fall for an eraser trap in the door. The door opens, the eraser falls with a klunk right onto the head of Kakashi, and the students are disappointed. Is this Ninja really a Jounin? And what does Kakashi think of these kids. In a low voice and emotionless mutter he says, "My first impressions of you. I hate you." The kids are stunned!
They assemble outside to introduce themselves. Naruto wants his teacher to start. Kakashi gives his name, says he has no intention of telling them his likes and dislikes, will not remark upon any dreams, and says he has many hobbies. Sakura complains, "So all we found out was his name."
Naruto describes himself openly. He likes cup ramen, he hates the three minutes he has to wait for the ramen to cook, his hobby is to eat and compare cup ramens, and he dreams of becoming greater than all the Hokages before.
