Before Setsuna could reply, Obito challenged him, "What's wrong? Are you worried that Setsuna-Bro is going to steal your 'genius' title?"
Kakashi glanced at him, saying calmly, "I have no interest in such a boring title. I simply want to test my own limits, that's all."
Setsuna asked, "You want to spar with me?"
Kakashi looked directly into Setsuna's eyes and answered seriously, "Actually, it's more like a request for advice. I'm developing a Lightning Style Jutsu, but it has a flaw: in a real fight, I might move too fast to clearly see the enemy's movements, which could open me up to a counter-attack. I heard that you are incredibly fast and can see every hand sign Asuma makes even when you are moving at high speed, so I wanted to ask for your guidance."
Obito bit his collar, his face a mix of envy and jealousy. "You jerk! You're already developing your own Jutsu! Damn it, you're ahead of me again."
Gai gave a thumbs-up. "As expected of Kakashi, my destined rival! How did you know I was also developing my own Taijutsu?"
Kakashi ignored both of them, focusing only on Setsuna.
Setsuna laughed. "If you want to improve your nerve reaction time, I can help you train. As for sparring, there's no need. Or... maybe we can compete to see who can catch that Peeping Tom first?"
Kakashi hesitated. "But I don't know where he ran off to."
Setsuna replied, "A pervert who dares to peep in broad daylight is aggressive. He might return to the same spot to commit another crime. Let's keep an eye out when we walk past there after we eat."
Kakashi nodded. He also wanted to catch the creep who had managed to escape him.
An hour later, all four children were staring at Setsuna in shock.
Setsuna had eaten twice as much food as all of them combined during the meal.
Obito stared blankly, asking, "Is eating a lot how you get good at Taijutsu?"
Setsuna nodded. "For a Taijutsu ninja, food is the source of life."
Compared to Goku, who could eat fifty times a person's meal in one sitting, his "eating power" was still too weak.
Gai pumped his fist with resolve. "My eating capacity is still too small! I must train harder! Starting tomorrow, I will double my food intake!"
He didn't have much to worry about, as being a ninja was a well-paying job.
An almost risk-free Rank D mission paid anywhere from 5,000 to 50,000 Ryo. Even after the village's cut and the team's split, a Genin could still walk away with a few hundred to over a thousand Ryo per Rank D mission.
Even someone with a huge appetite like Chōji Akimichi could only eat about 300 Ryo worth of BBQ at one gathering.
It's safe to say that even Genin could live quite well in the Leaf Village, as long as they didn't factor in the cost of consumables like shuriken, explosive tags, soldier pills, or the expense of paying Medical Ninjas for injuries.
The group left the BBQ restaurant and walked toward the bathhouse Kakashi had mentioned. Sure enough, they spotted a suspicious, lecherous figure hunched over on the rooftop window, peering inside with his backside sticking up.
"You damned pervert! Prepare for judgment from the Star of Justice, Lord Obito!" Seeing Rin's angry expression, Obito yelled as he leaped onto the roof and charged the white-haired man.
"It's Jiraiya, of course," Setsuna thought to himself. "Minato's grand-teacher, teacher, son, and student are all perverts. Is Minato himself really that straight-laced? Maybe he's just a secretly repressed pervert?"
Hearing Obito's shout, Jiraiya flicked his hair, which grew instantly and wrapped around Obito, restraining him.
"Obito!" Rin cried out worriedly, while Kakashi, already gripping his Chidori, rushed forward.
"Such powerful Lightning Chakra!" Gai's eyes were wide. Was this the Jutsu Kakashi had developed?
"What a nuisance of a kid," Jiraiya shrugged, casually grabbing Kakashi's wrist. "Kid, you shouldn't use dangerous Jutsu like that carelessly."
"How is that possible?" Kakashi was stunned. He thought his newly developed technique would be difficult for even a Jonin to handle, but this sketchy white-haired man was a ninja even stronger than a Jonin?
"Doesn't look like a good time for research today, haha. I'm outta here!" Jiraiya tossed Obito and Kakashi back and prepared to jump away across the rooftops.
Setsuna caught Kakashi mid-air. Kakashi urgently warned him, "Watch out! That person might be a spy from an enemy village! Go quickly and alert the Military Police Force!"
Though he didn't know what kind of secret information could be found in a bathhouse, a ninja this powerful suddenly appearing in the Leaf Village required extreme caution.
Setsuna whispered, "Didn't you want to test your nervous system's reaction to high speed? Keep your Jutsu focused."
Kakashi was confused, but the next moment, the surrounding scenery began to recede rapidly. The fierce wind made it nearly impossible for him to open his eyes.
"So fast!" Kakashi was shocked again. The "extreme speed" he could achieve by using Lightning Chakra to stimulate his cells was slow like an ant crawling compared to this velocity.
Jiraiya heard the whistling sound behind him, turned his head, and was startled. What the heck is that?
The distance between them was already small. In the moment Jiraiya hesitated, Setsuna hurled the Kakashi in his hand like a human "shuriken."
To Jiraiya's horror, Kakashi's Chidori precisely struck his rear end.
Jiraiya's face immediately flushed red. The next second, he let out a piercing scream, "crashing" from the air, plunging headfirst into the ground. His legs twitched uncontrollably.
Obito, Rin, and Gai caught up and saw the appalling sight of the pervert with a bloody backside. They all felt a phantom pain in their own backsides.
"Ouch, Kakashi, you hit way too hard," Obito immediately accused.
"It was..." Kakashi was about to say it was Setsuna who threw him, but after a moment's thought, he shook his head. "A peeping Tom like that deserves a lesson. Besides, given that guy's skill, the injury might not be as serious as it looks."
The next moment, there was a loud "poof" and a puff of smoke, and the person in the pit turned into a log.
Then, a burst of maniacal laughter came from above. "Hahahahaha! You're right! How could a great guy like me be hurt by little kids like you?"
The children looked in the direction of the voice and saw the white-haired man laughing loudly on the rooftop, though they could see his legs were faintly trembling.
Setsuna narrowed his eyes and chuckled. "Oh yeah? Then why do I see some red liquid dripping down your pant leg?"
Jiraiya's laughter stuttered, and he cleared his throat twice. "Do you kids even know who I am?"
Obito was indignant. "I don't care who you are! A creep like you needs to be arrested and thrown to the Military Police!"
"Since you don't know... then I'm out of here," Jiraiya declared, resolutely leaping toward the forest. He still had some pride. Not only was he caught peeping into the women's bathhouse, but he was also ambushed by a few kids. How could the Great Toad Sage show his face if word got out?
Setsuna immediately pursued him. Opportunities this good to test his strength didn't come along often, and since Jiraiya didn't want to reveal his identity, Setsuna was happy to pretend he didn't know who he was.
