He trained from three years in a distant town and has now returned to Konohagakure.
"Golly gee willikers, Bebe, my pet lizard. Konoha hasn't changed a bit!"
You might notice that lack of realism in the statement above. No one says "Golly gee willikers" anymore or names his pet "Bebe". Heck, does he even have to say "my pet lizard"? He's obviously just trying to give information to you, dear reader. He's clearly the stereotypical hero in a stereotypical shounen manga story.
"Oh, it's been a while, Hanataro."
"Oh, Riuka-sensei! Long time, no see."
This Riuka like your typical Academy student teacher, and he seems to be in good terms with our hero. Sadly, this is Riuka's only appearance, but he does provide valuable exposition to the story.
"Golly, are you entering that Chuunin exam"? Thousands of Genins are going to be in there, but I think that you've got a good chance! Although you failed Academy three times because of lack of chakra control, your immense chakra storage will definitely give you an advantage!"
Did you see that? This guy is just an extra, but he definitely knows what he is doing. He's taken care to reveal a bit of the character's skills and background, and even tells us what challenge awaits our hero. He only has this much of screen time, but he's certainly making the most of it. He's also pretty lucky to find Hanataro in this exact spot in Konoha, as well as why he's here for too. It's one coincidence after another, I tell you.
"Yes, I'll definitely become Chuunin! Believe it!"
Right, the protagonist in this kind of stories is the bubbly, optmistic, and idealist type of guy. It wouldn't be a stretch of the imagination if his wide blue eyes, sparkling with courage and hope, to take up half of his face. Of course, the random villagers who probably don't know this boy and don't care about the Chuunin Exam either will begin to start to mutter to themselves.
"That boy, Chuunin?"
"Impossible, he won't last ten seconds there!"
"Crazy forest folk and their unrealstic dreams."
"Go back to your pig dump, son!"
An arrogant commanding voice suddenly stands out through the deafening buzz of the villagers. Yes, it's time for the main antagonist to make his entrance!
"Hmpf. So, you've returned...", said the exceptionally handsome young man, about the same age as our hero.
Hanataro can only stutter in surprise.
"It can't be... you're... you're...!"
