Kakashi Hatake walked down the street with his blonde student at his side.
He and Naruto had come back from another training session out in the fields. Ever since Jiraiya vanished before Naruto could travel with him on his training mission, Kakashi wanted to re-connect to his student and train him until the Sannin returned. And to be honest, Kakashi had a lot of fun with Naruto. He certainly had a much better time training him than he did with Sasuke. That miserable traitor was never pleasant to be around, plus he always cheated and used his Sharingan to obtain strength and copied other ninja. But not Naruto, he worked hard to become strong, just as Kakashi did when he was a child before he obtained his Sharingan. Which was a trait he admired about his student.
But back to reality, Kakashi and Naruto were starved and he promised to treat Naruto to all the Ichiraku he could eat after a long day of chakra-control exercises.
"I hope you don't mind that I order about... 30 bowls of beef ramen, sensei!" the blonde kid said as he made his exaggerated estimate.
Kakashi laughed and then said, "Heh! I don't think you could eat that much, Naruto. Take it easy."
Without a warning, Kakashi's stomach suddenly released a loud growl which caused the blonde student to notice just how thin his teacher was. Naruto's own stomach released a similar sound, but it wasn't as loud as his sensei as the two continued to walk and the stomachs screamed one more time. The masked ninja patted his stomach and rubbed it and soon, the two arrived at Ichiraku Ramen. The student and teacher sat down in their seats and were greeted with Teuchi and his daughter Ayame. The two chefs looked pleased to see the two ninja arrive in their famed restaurant and went to their usual stations while the student and teacher sat in their comfortable seats.
Teuchi chuckled, "Well! If it isn't the handsome Kakashi and his trusted little sidekick!"
"Sidekick?!" outraged Naruto in a comedic fashion, "Since when am I the sidekick?"
Kakashi smiled, "Relax, Naruto. Besides, next to me, you're pretty much my version Robin."
"Since when do I run around in primary color-" he was about to asked and then he looked down at his orange and blue clothes, "Oh, yeah... I am Robin."
The masked man chuckled some more and pat Naruto on the back as he searched the menu as did his student. He wasn't sure what he wanted to eat this time, but he needed a dish that would fill him to the brim. He hadn't eaten lunch, so it was no wonder that his stomach almost screamed to be stuffed with food. Kakashi searched the menu over and over until he saw an old ramen bowl that he never noticed until now. It looked old, like no one had ordered one in years. But the description on the bottom said that it could cure a stomach in need of eating, which was what Kakashi needed as he was starved.
He asked, "What's this dish, Teuchi?"
"Oh..." the chef looked it over and said, "That's an old recipe I made years back when I was in school with Hakkaku. Not sure that I remember how to make it."
Kakashi told him, "It's called a Full-Bowl... Designed to help a man that needs to eat..."
"Well, I'm gonna order the usual and see where I go from there!" his student said out loud and made his decision.
The masked man shrugged and then returned the menu, "This sounds like the dish for me. I'll have one Full-Bowl and move on to some chicken-ramen with fish."
============================================
In the kitchen, Teuchi struggled to remember how to make the Full-Bowl back when he was in cooking school. It was designed to help satisfy a man's appetite and make them feel like they had a whole feast. But his memories on how to make it were clouded with his rival Hakkaku, who made dishes that did the opposite and made a man unable to stop eating their food and have whatever they ate become digested and turned instantly into fat. Teuchi tried to remember his own recipe but he remember that when he first made it, Hakkaku would interrupt him and show his own recipes into his face and distract him from his genius work. For a moment, he was tempted to ask Kakashi to ask for another ramen dish, but that would make him such a rude chef and he refused to reject a customers wishes. So he did his best in preparation of Kakashi ramen meal and prayed to the Gods that he made it right.
============================================
"Here you go! Hot and fresh!" the kind chef announced as he placed both the beef bowl and Kakashi's Full-Bowl on the counter.
At the same time, Naruto and Kakashi broke their chopsticks apart and said the usual prayer that most citizens in Konoha said before dinner. Naruto was too distracted and hungry to watch his sensei as he lowered his mask and ate his entire meal in a flash. Teuchi watched carefully and waited to see Kakashi feel full, hoping that he had used the correct recipe. Kakashi sat back in his seat soon after he had eaten and rubbed his stomach in satisfaction.
"Ahh... That was so good... Not sure I'll ever ask for one of those again..." he sighed.
Naruto smiled with noodles stuffed in his mouth, "Mmm-hmm!"
Teuchi sighed as well and relaxed as he turned back to the kitchen, but then he froze when he heard Kakashi shift in his seat and then he said, "Hold on, Teuchi!"
The nervous ramen chef turned around and continued to pray that Kakashi did not desire to eat more food, "Yes, Kakashi?"
"I actually could use another bowl of ramen. Could I have the chicken, beef, shrimp, with a side of salt-broiled fish, chips, and some water to wash it all down?"
Teuchi almost fainted when he realized Kakashi had fallen under the spell and that he had in fact used the incorrect recipe. He would have to fix the situation before it came out of hand, but he could risk his business and tell Kakashi that he had basically been poisoned. So the kind chef smiled and returned to the back to make Kakashi's big meal, his daughter oblivious to the events to come while Naruto stared at his sensei when he heard him order all that food for himself.
"Whoa, sensei. Since when did you have such an appetite?" he asked.
Kakashi rubbed his stomach, which was strange, because it felt like he hadn't even eat a bite, "Not sure. But I could use some food. I hardly ate anything since breakfast this morning."
=============================================
Teuchi watched and tried his best to hide his horror as Kakashi started to eat, much slower this time while Naruto was distracted. Kakashi stuffed the chicken flavored ramen noodle into his mouth and did not even chew as he consumed more noodles than Naruto did. He sucked them all into his mouth and did not even breathe as he inserts chips into his maw and moved on to the other ramen bowls that he wanted to eat. Soon, he moved on to the pork, beef, and shrimp flavored ramen as he loaded his mouth full of noodles and then swallowed them all down at once.
After a breath, he drank some water and continued this motion over and over until he was done and sat back in his chair with his mask returned to his handsome face. Teuchi looked over the counter and could see Kakashi's stomach had expanded to its limits. Kakashi's belly was now noticeable, as if he had swallowed a basketball and it inflated while still inside him. He rubbed his stomach, after having eaten over 8 ramen bowls, various side-dishes, and almost 2 gallons of water to wash it all down.
It was a miracle Kakashi hadn't burst or even moaned. But that was a side-effect of the first ramen dish he ate. Hakkaku designed his formula so that it stretched out the stomach more and numbed out the pain of being full.
The now satisfied Kakashi remained oblivious to his new large belly even as he rubbed it and paid for both himself and Naruto.
Teuchi nodded to both the shinobi and waved to them until they were both out of sight. He then bolted into the kitchen and search for the broth he used in Kakashi's first dish as well as his recipes as his daughter closed down shop.
Teuchi then said to himself in a panicked voice, "I have to find a way to reverse this fast! If I don't Kakashi won't stop eating until he's as fat as a cow!"
