The Terror of the First floor

With the barrier down the tower participants all began their journey into Caelid, some people decided to head south while others went east. A few people headed north, Noah floating in their watched the multiple people heading in different directions. Noah looked at the familiar people and was shocked by his discovery. 

" Isn't that man in the iron suit Tony Stark from the MCU, and is that Kenpachi and Sirzechs Lucifer? Woah, does my tower connect to different anime worlds?" Noah felt excitement and shock about his discovery. Not long after Noah noticed a few people entering a point of interest on the first floor, he teleported to the Gael tunnel and saw 2 different groups there, the first group was the MCU group. Tony Stark, Hawkeye, and black widow were fighting the monsters in the tunnels with a different group of people. The second group was only formed with 2 people from the Dxd world. One was a white-haired teenager and the second was a middle-aged man with black hair with blonde bangs. Noah watched how Azazel causally killed the miners and Radahan soldiers and flirted with Natasha.

" Come on beautiful why don't we get something to eat after this, I know this great Japanese restaurant." While flirting Azazel looked at Tony inside his Iron Man suit and wanted to ask him about it. After the group cleared out the monsters in their area Tony landed next to Azazel and Vali wishing to ask them questions. While fighting he noticed Azazel was using some strange devices while Vali had these white mechanical wings behind him the entire time. He asked Jarvis to scan them but was surprised when Jarvis was unsure of the technology that was being used.

" Hey buddy what are those devices you're using and those white wings? Who made them and what are they made of?" Tony unable to hold his curiosity asked Azazel and Vali about their items.

" What a coincidence I was about to ask you about your armor. Well, the devices I used were failed Sacred Gear I tried to create, thankfully the enemies we meet so far are low-class in strength. As for the moody kid over there he's the wielder of the Divide Dividing." Tony Stark was slightly confused about the terms Sacred Gear and Divide Dividing.

" What are Sacred Gears and the Divide Dividing?" Natasha looked at Azazel and tried to get information out of him.

" It's not surprising since you haven't interacted with the supernatural side of the world, but before we do anything else how about we introduce ourselves?" Azazel although seeming carefree was vigilant since he entered. When they first entered he noticed a few different people and the energy in their bodies. He listened to a few conversations and from what he heard he came to a shocking discovery. 

" You don't recognize me the great Tony Stark. I am Iron Man, I've been In the news for a while from my actions." Tony Was surprised that Azazel didn't recognize him, he briefly thought maybe the supernatural he talked about secluded themselves before he heard Azazels words.

" As I thought we may come from different worlds, maybe different universes. I am Azazel Governer General of Grigori." Showing off his 6 pairs of ink-black wings shocking the group.

-----------------------------------------------------------------------------------------------

Noah left the cave wanting to see what else was going on, he saw different people fighting the monsters. Many people kept dying and his Points kept pouring in, as he was flying he saw a pink-haired teenager using fire magic to punch a monster. Noah flew near the minor Erdtree and saw a group of people nearing the minor Erdtree boss. Being a mini-boss the boss was more powerful than the majority of the monsters. The group of people that arrived was the two espadas from the two bleach worlds Grimmjow Jaegerjaquez and Szayelaporro Granz as well as Sirzechs and Grayfia from the DxD world. Arriving near the minor erdtree the two groups came face to face.

" This place is really full of surprises, the two of you look human but by the spiritual pressure and the energy I sense in you I can tell you something else. You're not hollows nor soul reapers, I want to capture you and try my experiments on you too." Szayelaporro seeing Sirzechs and Grayfia had a dangerous glint in his eyes. Sirzechs began to control his power of destruction ready for a battle. Grayfia also prepared her ice magic in preparation for the fight between them and Szayelaporro. Before the group could begin their fight a loud explosion caught the attention of the group. 

By the Minor, Erdtree Grimmjow was exchanging blows with the Erdtree avatar. Grimmjow swung his sword in attempting to wound the avatar but found it difficult due to the avatar's powerful attacks. Grimmjow growled in frustration as his blade clashed against the sturdy bark of the Minor Erdtree Avatar. Despite his relentless assaults, each swing of his sword seemed to only graze the creature's thick, tree-like skin. The Avatar retaliated with earth-shattering blows from its colossal staff, each strike forcing Grimmjow to retreat, narrowly dodging the crushing impact.

"Tch, stubborn piece of wood," Grimmjow spat, his eyes burning with fury as he slid back. He darted forward again, releasing a powerful slash aimed at the creature's legs, but the Avatar parried with its staff, sending him flying back several meters.

Grimmjow's body slammed into the ground, creating a small crater. He groaned as he stood up, shaking off the dust and flexing his arms, already eager to jump back into the fray.

"I'm not done with you yet!" he roared, his feral grin never fading. Just as Grimmjow was about to charge again, a flash of light appeared in front of him. Szayelaporro materialized from a Sonído, standing between Grimmjow and the Avatar.

"You're getting reckless, Grimmjow, No sense in being so hasty. Let me analyze this thing first. I'd hate for you to get squashed before I get to finish my experiments." Szayelaporro mused, his tone dripping with amusement. His eyes narrowed as he glanced at the towering creature, then back at Grimmjow.

 "I don't need your help, Granz. Stay outta my way." Grimmjow sneered as he prepared to attack once more. Before the bickering could escalate, an oppressive wave of energy washed over them. Szayelaporro and Grimmjow both turned to see Sirzechs and Grayfia approaching, their auras glowing with power. Sirzechs' crimson eyes were fixed on the two Arrancar, a calm but lethal energy swirling around him as his power of destruction began to manifest. Grayfia, standing beside him, was poised and deadly, her silver hair glowing under the golden light of the nearby Erdtree, her fingers already crackling with icy magic.

"Ah, how foolish of me to forget my two other experiment materials," Szayelaporro muttered with a smirk, turning to face the two. His eyes gleamed with curiosity and a sadistic glint as he sized up his potential new test subjects.

"I would advise against that. You're not the first to underestimate me," Sirzechs said calmly, his voice dripping with dangerous intent.

"Ah, but I enjoy surprises," Szayelaporro replied, his grin widening. Szayelaporro raised his sword and began to put it inside his throat.

" Let me introduce myself. I am Espada number 8 Szayelaporro Granz. Sip Fornicarás." A powerful energy was being emitted from Szayelaporro as his body began to transform. His body grew and became round but pink energy left his body as he shark down. Once finished he appeared in his Resurrección form and began to attack.

Without another word, Szayelaporro raised his hand, summoning a barrage of spiritual tendrils that shot toward Sirzechs and Grayfia. Sirzechs responded instantly, his power of destruction consuming the tendrils before they could reach him, reducing them to nothingness. Meanwhile, Grayfia unleashed a volley of razor-sharp ice shards, forcing Szayelaporro to leap back, evading the deadly projectiles.

"You'll have to try harder than that!" Grayfia's voice was cold and precise, her magic swirling around her as she prepared another attack. 

Before Szayelaporro could counter, a shockwave from Grimmjow's side of the battlefield blasted through the area. The Erdtree Avatar swung its massive staff, aiming directly at Szayelaporro, who sidestepped just in time. Grimmjow, however, wasn't as lucky, the force of the Avatar's attack sent him crashing into a nearby rock formation.

"Grimmjow!" Szayelaporro called, his voice betraying a rare moment of concern.

"Shut up! I'm fine!" Grimmjow barked, his body enveloped in a blue aura as he pushed himself up from the rubble, glaring at the Avatar. 

Sirzechs raised his hand and sent a powerful wave of destruction toward Szayelaporro, forcing the Arrancar back into defensive mode. Grayfia seized the opportunity and launched a flurry of freezing winds in Grimmjow's direction, her icy magic freezing the ground beneath him as she aimed to immobilize him.

"What the hell! You wanna play too, huh?! Fine, let's see what you've got!" Grimmjow roared, leaping into the air to avoid the ice. His eyes blazed with rage as he drew his sword again. 

 "Grayfia, let's not waste time. We'll finish this quickly." Sirzechs remained composed, his power steadily growing, the ground beneath him cracking under the sheer force of his energy. The two groups began to charge up their attacks while paying attention to the Avatar and its movements. Instead of charging in and swinging its staff this time the Avatar conjured rays of light which homed at them. 

As the battle between Grimmjow, Szayelaporro, Sirzechs, and Grayfia intensified, the Minor Erdtree Avatar's power began to spike. Its blows became heavier, faster, and far more brutal. The golden energy surrounding it grew denser, warping the air around it with each swing. The ground splintered beneath its feet, shockwaves rippling through the battlefield.

Its limbs started to pulse with golden light, roots surging from the earth like tendrils, wrapping around anything in their path. The golden mist thickened, draining the energy of anyone caught within it. Grimmjow, now struggling against the sheer force of the Avatar's attacks, was thrown back, unable to break through. He growled in frustration as a massive swing from the Avatar's club crashed into him, sending him flying through the air. Szayelaporro narrowed his eyes as the roots closed in on him, his voice laced with amusement.

"This thing is... fascinating." But even his intrigue couldn't change the fact that they were being overwhelmed. The sheer power of the Avatar was too much.

On the other side, Sirzechs and Grayfia were pushed to their limits. Sirzechs unleashed his destructive power, obliterating the roots that surged toward them, but the Avatar's attacks came faster and stronger. Grayfia's ice magic barely managed to contain the oppressive heat radiating from the Avatar.

"It's becoming stronger," she said, her voice steady but her eyes sharp. Suddenly, the Avatar let out a roar, releasing a powerful wave of golden energy that shook the entire battlefield. Sirzechs glanced at Grayfia, his expression grim.

"We're not here for this. We need to fall back."

Grimmjow, now forced to his feet after being launched across the field, clenched his fists in frustration. Szayelaporro, though reluctant, scoffed.

"A retreat then... for now," he muttered, stepping back as the Avatar's overwhelming energy consumed the area.

With no choice, both groups withdrew, the immense power of the Minor Erdtree Avatar forcing them to abandon their fight. Its golden form stood tall, radiating divine energy, a force that neither side was prepared to challenge any further. For now, they retreated, knowing they would need to return stronger if they wanted to stand a chance against it. The Minor Erdtree Avatar stood next to the tree its aura warding off those nearby.

-----------------------------------------------------------------------------------------------

" Hmmmmm, at this rate they won't be able even to make it towards Rahadan." Noah watched as the group of people wasted a lot of time and energy on the weaker monsters and fought with each other. He must admit that seeing the fight between the espadas, Sirzechs, Grayfia, and the Minor Erdtree Avatar made him feel overwhelming joy and excitement. 

He watched as some groups gathered up loot from the defeated enemies and areas of interest. As time passed the deeper into caelid they headed and the more points of interest people reached the more kept dying. After a few hours, a little over 100 people made it to Castle Redmane. Among these people, there were the two captains from the bleach world Kenpachi Zaraki and Toshiro Hitsugaya, the two Espada Grimmjow and Szayelaporro, Azazel, Vali, Sirzechs, and Grayfia from the dxd world, as well as others from different animes. All of them stood in the waiting area exhausted and covered in injuries, as the sunset and night came Jarren came out of the castle and stood over the crowd.

" Before we begin allow me to paint you the full picture. General Radahn is cursed ever to wander. Eaten from the inside, by Malenia's scarlet rot, his wits are long gone. Now he gathers the corpses of former friends and foes alike, gorging on them, like a dog. Howling at the sky.

But now, we must make merry. Oh, gathering of champions! The revels begin! The celebration of war! The Radahn Festival!" As Jarren Spoke a blue hologram displaying the cut scene from the game played. Once he finished speaking the people all there were teleported to the vast desert Radahan was. 

As the crowd materialized in the vast desert, a suffocating silence fell upon them. In the distance, they could feel it, an overwhelming, oppressive aura. It was unlike anything they had faced before. General Radahn towered on the horizon, his colossal frame barely moving, yet his presence alone sent shivers down most of their spines. 

Suddenly, without warning, Radahn drew back one of his massive gravity arrows. The air crackled with energy as he released it, the arrow shooting through the sky with blinding speed. It tore through the air like a bolt of lightning, too fast for any to react. The impact was instant and brutal, a person standing too close to the front was hit, their body exploding on contact and turning into a golden light.
