At one of the IGO branch headquarters a meeting was held to discuss the resent attacks on the bio domes and what to do about it, they concluded the Bishokukai were finally making their move.

"The IGO must act, we need the Four Heavenly Kings, Toriko, Coco, Sunny and Zebra" the Bureau Director said.

"You want us to release Zebra from prison?" someone asked.

"There is no other choice is there? You need the best weapons to win a war, as for Zebra she'll keep him in line" the director said.

"Sir, i anticipated this and planned accordingly, Toriko and her are on their way to Biotope 1" another said.

~~~~~

Ao wasn't surprised to get a call from IGO, unlike the other four she worked quite closely with the organization as he father was its president.

Currently she was riding on Shiro on her way to Biotope 1, she was surprised they picked this place out of all of them but she supposed letting Shiro into the arena would be good training for him.

Ao soon arrived at the Biotope and landed in the hanger with Shiro.

"Hey Ao, you're early!" Someone called as she hopped off the White Dragon.

"Mansam" Ao blankly greeted the bald man in charge of Biotope 1.

"Huh? Did you say handsome?" he asked cupping his ear and grinning with excitement.

"No" Ao bluntly said crossing her arms "Now why was i called? And here of all places? What do you mean i'm early?" she asked.

"You're early cause Toriko hasn't shown up yet and as to why and here, you'll see" Mansam told her with a teasing grin.

Ao sighed "Must be something big if you don't want to tell me right away" she said.

"You have that much right, now come on" Mansam said and started leading the way.

"Oh hey i was wondering if Shiro could go into the arena, he could use the training" Ao said before she would follow.

Mansam looked back to the White Dragon, now the size of a medium commercial plane.

"That's a White Dragon isn't it? I suppose it's fine, i doubt it'll outshine the main attraction" Mansam said.

'Main attraction? What sort of monster have these guys cooked up this time?' Ao wondered.

"Hey you!" Mansam said calling someone over.

"Yes sir?" they asked.

"Take this big guy and let him into the arena" Mansam said pointing over to Shiro.

Shiro growled at them in warning as they got closer, Ao patted his snout "Shiro is a bit protective, he won't let anyone i personally don't trust near me" she told Mansam.

"I see, in that case you know the way" Mansam said.

"I'll meet you in the bleachers" Ao said leading Shiro away to the arena gates.

~~~~~

"Alright Shiro, i know you haven't fought much but i believe in you, just listen to your instincts and don't let the other guys boss you around" Ao smiled as she petted the top of Shiro's big head.

Shiro cooed and nudged her with his head, Ao giggled a bit and hugged his snout "I'll be watching, so don't let me down" she told him.

Shiro huffed as he nodded, then Ao let go and ran off not looking back as she headed to the bleachers where Mansam was already waiting.

"So how did you come across a White Dragon? And tame it no less?" Mansam asked once she sat next to him.

"I found an egg under my house and Shiro hatched from it, that was three years ago so he's still pretty much a hatchling" Ao said.

"I see, well Toriko should be arriving by now, i'm off to greet him" Mansam said before leaving.

Ao just absentmindedly nodded and watched as the next round started.

Shiro walked into the arena with the rest of the creatures and looked around the crowd looking for something, rather someone, spotting the blue haired woman smiling at him the White Dragon grew more confident.

Then as soon as the bell rang Shiro dominated the whole field with a powerful roar before attacking the frightened creatures, skillfully and mercilessly killing them.

~~~~~

Soon Mansam returned with Toriko and Komatsu in tow just as Shiro ripped into a Troll Kong.

"Amazing, that White Dragon of yours has some serious power even for just a hatchling" Mansam said taking the seat next to Ao, with Toriko and Komatsu sitting on the other side.

"Of course, after all i raised him" Ao smirked as the arena was cleared out for the final fight.

"And now, it's time for today's main event and the contenders are entering the ring!" an announcement said.

"Oh, it's starting" Mansam said.

One by one the less interesting creatures were announces as they were released into the arena growling and roaring at each other, each one trying to intimidate the other.

"A-amazing!" Komatsu said, amazed by each creature.

"The real surprise has yet to come, the main attractions for today are the legendary beast waiting behind the fifth and seventh gates" Mansam said.

"Sorry to keep you waiting, behind Gate 5 the strongest and most powerful of the wolves, born in ancient times ... the Battle Wolf!" the announcement said.

The entire arena practically shook from the excited cheers of the crowd.

"No way" Ao muttered completely floored by shock.

Toriko just as shocked as Ao, stood up to have a better look at the beast of legend just behind the gate "You gotta be kidding me, the actual Battle Wolf? From the Death Gore plague?" he asked.

"The what plague?" Komatsu asked confused.

"It was many thousands of years ago when the Death Gore reigned, no one's certain how they evolved it was as if they were born from the bowels of the earth, with a body length of fifty meters and weighing one thousand tons, they were super herbivores with an endless hunger"

"They were devils that formed herds and consumed all of the greenery moving down all of earth's plant life, they left a world of death in their wake, the footsteps of the Death Gore were said to be the countdown to a species extinction"

"After eating one continent into oblivion they set their sights on the world's largest continent, a green paradise, but they were never able to consume even one blade of grass in that wonderland"

"When the demons tried to lay claim to that land they were completely wiped out by one, solitary creature, the Battle Wolf" Mansam explained.

It was certainly a sight to behold, the legendary Battle Wolf with it's shiny white coat and regal appearance, but there was something about this one in particular that seemed off to Ao.

"Most people have bet on the Battle Wolf but the second favorite to win is Shiro, waiting behind gate 6" Mansam said as a screen showed the odds of one creature winning.

~~~~~

There seemed to be some trouble with the fragrance machine or something, Ao wasn't completely paying attention to what that clutz Rin and Mansam were going on about.

She was more focused on the Battle Wolf and why something felt off about it, her suspicions were only confirmed when the wolf didn't move out of the way when all the other beast ganged up on it.

"Mansam, is that Battle Wolf a female?" Ao asked turning to the chief.

"Uh yeah, why do you ask?" Mansam asked.

"Toriko!" Ao called and he turned to her, they shared a look.

"Yeah" Toriko nodded and they both rushed down to the arena dome where Toriko punched a hole through the thick glass.

They jumped down to the arena where Ao went over to Gate 6 and let Shiro out while Toriko dealt with the other beast.

Shiro leapt out of the gate and over to one of the other beast tackling is, preventing it from attacking the Battle Wolf, defending her along with Toriko despite the fragrances messing with his senses.

Ao went over to the Battle Wolf once the other beast were firmly occupied with Toriko and Shiro, hoping she'd respond better to a fellow female.

"Hello there, it's okay now we're here to help" Ao said not braking her gaze from the Battle Wolf's.

It seemed she understood the humans intensions as she let herself collapse.

Ao cautiously walked closer never braking eye contact with the Battle Wolf and placing a hand on her nose once close enough.

The Battle Wolf visibly relaxed and allowed Ao to pet her.

"That it, just relax" Ao gently coaxed with a smile as she petted the Battle Wolf, her fur was incredibly soft, like a fresh towel.
