Rias waited patiently.

She was at a local shop, a shop that specialized in gardening and farming supplies. She had been plotting and waiting, and scheming was her forte. She had her familiar sneak into Naruto's house, and spill the nutrients he used to water his houseplants with. She then had Akeno wait outside of Naruto's apartment, and call her when he left to go get more.

So she had her cutest, appropriate clothes, for such a thing.

Slightly torn work jeans that were tight around her butt, and a loose fitting top that was cut off halfway between her jeans and her belly button. She showed off a seductive amount of skin, and she knew that she would get a reaction from him.

Naruto entered the store.

"Oh-"

"Sup." Naruto just raised a hand casually when he passed right by her, and her only response was to raise her hand back. Naruto went straight to what he needed, grabbed it without even looking at anything else, not a single thing more. Just a casually greeting, followed by passing by her without so much as glancing at her.

Rias was slightly frozen.

'What do I say?' Rias thought, since she had no expected him to just greet her and then pass by her like that. She expected him to stop for a moment.

"Ah, Gremory-senpai, you like to garden too?"

"Why yes, I do love it."

Rias nodded to herself, and she saw how that imaginary conversation played out in her hand. Rias blinked when she saw the blond hair walk by her, and she put extra emphasis on her butt as she bent over. She made it look like she was having trouble deciding between two different things.

Naruto slowed down and twisted his neck a little to look at her when he heard her, but instead of being focused on her butt, he only stared at her butt for a brief moment, before something else seemed to attract his attention.

"Pffft... you might want to go look at yourself in the restroom."

With that, Naruto turned and kept walking away. Rias blinked, not expecting that to be how that conversation (one sided) went. She blinked and walked towards the restroom, attracting a lot of eyes as she did so. She didn't pay any real attention to the blushes and whispers that she got, since their eyes meant little to her. She just entered the restroom silently, and she looked at herself.

Beautiful.

She turned around and looked at the mirror again, only for her cheeks to flush when she realized that her jeans were too tight on her butt. They had been tight enough, that she didn't even notice the rip that went right down the butt of her jeans.

"... That..." Rias looked at her jeans with her face flushing.

She had been so into her own thoughts, she never noticed that she ripped her pants. Rias got her phone out, and she called Akeno.

She needed new pants.

-Days Later-

This time, her plan was different.

Ramen.

She paid a local ramen shop, to host an event. The event was just to eat a very large, abnormally sized bowl of ramen. She had her own family chefs design the ramen bowl, to make it look as appealing as possible. She then had the ramen chef hypnotized into mastering how to make the bowl himself, without him realizing that he had not been the one to create the ramen himself.

Ramen Challenge
Eat the Leviathan, Win a Free Prize

According to Akeno, Naruto loved to eat ramen, and would regularly go out of his way to find ramen shops and stalls, in order to sample their ramen. This was a shop he had already been to before, and Rias was confident. She had her familiar take a human form, and made sure that Naruto got a promotional poster for the challenge.

"So... THIS is the Leviathan."

Serafall Leviathan showed up, and while Rias sighed that it wasn't Naruto, her familiar reported to her that Naruto was on his way. It would seem that Serafall had heard of the ramen challenge featuring her title, and decided to check it out. It was a professionally made ramen, so word had most likely spread from her family chefs to the Sitri family chefs, who then allowed the rumor to spread to Serafall herself. Thankfully, Serafall didn't even notice her as she sat down, more concerned with the ramen.

"I'll order the Leviathan!" Serafall cheerfully exclaimed.

"Coming up."

"He's on his way." Akeno nearby whispered to her, even Yuuto nodded his head.

Casual.

Since one on one seemed to be a challenge, she decided to make the atmosphere more casual by having her friends with her. That way if she failed to attract his attention, they could help her out in a normal, casual way. She learned from how casual Naruto had been at her previous attempt.

Naruto entered the shop.

"Woah, this is HUGE!" Serafall shouted at the top of her lungs when she saw a super large serving size of ramen placed in front of her. It was packed full of meats, veggies, and everything else to the point the bowl was almost overflowing. "No wonder it is the Leviathan... well, time to dig in!"

"Damn... that looks good." Naruto muttered to himself, mouth watering. "I'll have 3 bowls of the Leviathan." Naruto claimed.

Rias' jaw dropped when Naruto said he would have 3 bowls, finding that extremely hard to believe. She looked at Akeno, who was taken slightly aback by his words, but she still had a smile on her face. Naruto sat down between Rias and Serafall.

"3 bowls, isn't that a little much for a guy your size?" Serafall asked as she broke her chopsticks apart, and got prepared to dig in.

Naruto showed visible anger.

"Are you sure YOU can even finish that ONE bowl?" Naruto asked her, and Rias could see that she lost her chance to make a casual conversation. Naruto's implications did not go unnoticed by the diplomat of the Devil Kings, and she leaned forward.

"More than you."

Sparks flew between their eyes.

"Here is your order sir."

"I want 3 more bowls!" Serafall proclaimed loudly to the chef, who had money signs in his eyes the second she shouted that out.

"Yes miss!"

"I want 3 more ON TOP of these 3!"

Soon enough, Naruto and Serafall were loaded up with ramen. The two of them placed their hands together, and stared at each other. Rias saw her chance coming up.

There was no way a human could beat a devil when it came to the Sin of Gluttony.

She would comfort him when he lost.

"Oh, what is going on here?" Rias turned and saw her brother walking into the ramen shop, with his best friend Ajuka with him. She saw her peerage become more alert to the fact that 3 of the devil kings were together in a single ramen shop.

[Music: RWBY Capabilities Unseen]

Naruto and Serafall started to eat.

They cleared the first bowl within moments, and started on the second bowls they were working on, which didn't take that long for them to clear as well. Naruto and Serafall glanced at each other between slurps of their noodles. In just as much time as the first bowl was cleared, the second bowl was cleared.

'Big appetite.' Akeno looked at her large sized bowl of ramen, that was not the Leviathan.

Rias was just shocked when she saw the stack of bowls grow by another bowl, as they finished their third bowls and continued onto the 4th with demonic speed. She saw Serafall start to slow down slightly as the two of them finished the 4th bowl in about the same time as it took them to finish the 1st through 3rd bowls of ramen.

Then the gap widened when she slowed down even more.

On her 5th bowl, she started to go half speed, while Naruto continued on. He already finished the 5th bowl by the time that she was halfway down, and by the moment she finished the 5th, he was already eating his 7th bowl of ramen. Serafall groaned as she started her 6th bowl, and she looked over towards Naruto. She looked down at her ramen bowl and more slowly started to eat it.

He was on his 8th.

He was on his 10th by the time she finished.

"Tag out... tag out." Serafall stood up with a bloated belly, and she tagged Sirzechs for her when she saw him. She wobbled, while Naruto kept eating as his new challenger sat down and started to scarf down the ramen.

Sirzechs didn't even question the contest, but it seemed fun so he started to dig in. The food was delicious, so he started with the same demonic speed that Serafall started to eat with. He ate even faster than Serafall when he noticed the gap had only widened, and was soon on his 3rd bowl by the time that Naruto reached his 16th bowl.

'He is a demon...' Sirzechs thought as he quickly finished off his 4th bowl and started his 5th bowl.

The kitchen staff were working in overdrive, their shouts and screams from the kitchen could be heard, while the main ramen chef had a sparkle in his eye. Naruto started to speed up when he actually noticed that Serafall had switched out.

When Sirzechs finished his 5th bowl, Naruto was on his 18th bowl.

'Bring out all the switch outs you want... I'm going to win.' Naruto made eye contact with Sirzechs, while Serafall laid on her back, on the floor on the resturaunt. She held her belly in discomfort, but she still watched the competition going on. A fire was ignited in his belly when he saw that there was another person in line after Sirzechs, meaning that he had more people against him.

Sirzechs got to 9 bowls of ramen before he put his hands over his mouth halfway through the 10th bowl.

He switched out with Ajuka, who nodded his head.

No questions asked, Ajuka just accepted the fact that he was next up, and finished off Sirzechs unfinished ramen. He felt the heat as well, the heat of the competition when Naruto just started to eat even faster.

Serafall only ate 6 bowls.
Sirzechs ate 9 and a half bowls.

Even when you combined the amount they ate together, it didn't add up to the fact he was finishing his 22nd bowl of ramen, and seeing a new challenger only made him speed up. Somehow, he was eating without even spilling a single drop of broth, or any of the ramen going anywhere but in his mouth.

'This boys is a demon... a true, unrelenting force of gluttony.' Ajuka thought as he finished his 1st bowl.

Naruto finished 2 more bowls in that time.

Ajuka was not a big eater, so by the time he was on his 4th bowl, he felt himself ready to burst at the belly. He didn't even finish his fourth bowl before he dipped out of the competition, and he collapsed backwards onto his back. Naruto grabbed his unfinished bowl, and started to finish it off himself.

Insult to injury.

"... Wow..." Rias had her eyes widened when Naruto stood up.

He just defeated 3 Devil Kings, 3 of the 4 Satans, in a competition of gluttony. Rias was taken even more in shock when that very thing hit her even harder when she looked at the 3 devils on the floor, moaning in pain as they held their stomachs. Naruto sat back down and he kept eating, something the ramen chef was happy with.

"Losers pay for winners, so put my ramen on their check." Naruto gestured to the 3 on the floor.

Serafall sent a shaky thumbs up, to show that she was willing to face the consequences of her loss.

'Even 3 satans weren't enough to match him... his gluttony...' Rias felt her face flushing as she watched a human man outdo not 1, but 3 satans in a battle of sin. She had no words, and just watched Naruto stand up and leave when he was done. Not only was her more crafty than a devil, but he was more gluttonous than multiple devils.

"He just tempted 3 satans into falling into gluttony... a human just made 3 devils lose to the sin of gluttony." Akeno described the situation for what it actually was. A human getting devils to lose to their gluttony, and then humiliating them further.

30 bowls, and half of Ajuka's bowl.

If you combined all of the satans meals together, it was still less than what Naruto ate. He didn't just defeat them on an individual basis, he defeated their gluttony as a group effort. At the rate he had been eating, it was possible that he could have kept eating and outdone the entire lot of the devil kings.

"The Gluttonous King."

"Young Master... thank you for visiting my shop!" The ramen chef rushed out from behind the counter and bowed to Naruto.

Naruto just sent him a thumbs up.

"You serve awesome ramen." Naruto stated with a confident air.

He left, the victor of a hard fought battle.
