A Mutant's Ascension

[4th Division, Seireitei]

Everything was completely calm inside the Seireitei like any other normal day. Everything was calm and silent as everyone went on with their usual life… most of the Shinigamis could be training.

All of a sudden everything changed as a loud siren started to blare throughout the whole Seireitei. Everyone stopped whatever they were doing and turned towards the barracks of the 12th Division. That is from where the siren seemed to be resounding.

Normal Shinigamis didn't know the meaning of the siren but it was a completely different story for the Captains. But the Captains didn't have the time to stay idle as they were being summoned by the Captain-Commander.

"Taichou, what is the meaning of that loud siren?" Isane Kotetsu asked her Captain curiously.

"The siren means that we have some type of emergency in the Human World" Unohana Retsu explained in a polite tone.

"But we are being summoned by the Captain-Commander. Stay beside me Isane" Unohana said with a kind smile on her face. Isane immediately nodded her head. The next second, both of them were gone.

After a few seconds, the two of them appeared inside the 1st Division. They were currently standing right outside the Captain-Commander meeting hall.

Some Captains were already there along with their lieutenants. Everyone noticed Unohana's arrival and they gave her a polite nod. Unohana returned the same gesture.

After a couple of minutes, the rest of the Captains also arrived along with their lieutenants. Only the Captain of the 13th Division, Jushiro Ukitake seemed to be missing but nobody complained.

The Captains quickly entered the hall as they started to take their designated places and their lieutenants diligently followed their Captains and sat down behind them.

"Captain Jushiro Ukitake is unable to attend due to his health" Unohana said and the Captain-Commander gave a small nod and then he hummed his throat.

"My Division has noticed a source of a huge amount of Spiritual Pressure in the Human World. As for now, I don't know if it is a Hollow or not but the Spiritual Pressure is strong enough to equal Captain-Commander's" Mayuri Kurotsuchi reported and murmurs broke throughout the room.

"Preposterous!!!" The Captain of the 7th Division, Sajin Komamura screamed in protest. This was something beyond the imagination.

Unohana noticed Sosuke Aizen's eyes grew wide with the news. Unohana internally smirked and cursed at the same time.

Hela was having fun while she was stuck here… life was so unfair. She was sure that it wasn't Reo as Reo's Spiritual Pressure was way stronger than the Captain-Commander. His max output was so strong that she couldn't even sense it any longer.

"Is that so??" The Captain of 11th Division, Zaraki Kenpachi, asked excitedly about the prospect of getting to fight a strong opponent.

"There must be some type of mistake" the Captain of 2nd Division, Soifon concluded and Mayuri Kurotsuchi clicked his tongue in annoyance.

"Dumb woman! My sensors are perfect" Mayuri Kurotsuchi said in an irritated tone.

"How dare…" Soifon wanted to retort at the insult thrown in her direction but she was cut off when the Captain-Commander slammed his cane on the floor.

Unohana noticed that the Captain of the 9th Division was quite tense. She concluded that Kaname Tosen was in Aizen's fold. Reo had only talked about Aizen.

"I have also sensed the Spiritual Pressure. We will be visiting the Human World, if there is someone out there whose Spiritual Pressure is equal to me then we need to deal with it as quickly as possible" the Captain-Commander spoke and no one dared to refute his statement.

"Captain Unohana, Captain Soifon, Captain Kurotsuchi will evacuate the town with the help of their Squads and they will also erect a barrier around the town while the rest of us will neutralize the threat" the Captain-Commander commanded slowly and everyone nodded their heads.

Unohana was feeling conflicted. On one hand, she was glad that she wasn't ordered to fight as she didn't want to lose but on the other hand she wanted to fight as she wanted to get bloody.

"We are leaving as soon as the Senkaimon is prepared. Captain Unohana, Soifon, Kurotsuchi, prepare your Squads" the Captain-Commander said and Unohana gave a small nod before leaving the chambers followed by her lieutenant.

Similarly, Captain Soifon and Captain Kurotsuchi also left the chamber with their lieutenants as they needed to prepare their squads…

[Human World, Karakura Town]

Kisuke Urahara was standing straight while blood was dripping down his free arm. He had used his free arm to defend himself from the Hado and now his free arm was charred and almost unusable until it was healed.

"You sacrificed your arm?" Hela asked with a grin as she tilted her head. Hela had a sick grin on her face.

"Ah, not everyone can be strong like you" Kisuke Urahara said with a grin as his charred arm was surrounded by a mild green glow. Hela was quite familiar with this glow as she had seen Unohana using this technique multiple times.

"You can use Kaido? That's good…" Hela said and started to cackle. This time Kisuke Urahara wasn't surprised as he knew that Hela would recognize this technique too.

She seemed to be quite knowledgeable in Kido Spells and she also owned a Zanpakutou. Slowly Kisuke Urahara's hand was completely healed and he was slightly surprised that Hela didn't attack him during this time.

Urahara frowned when he sensed several Spiritual Pressures coming in their direction. He recognized all of them and since he was able to notice them he was pretty sure that Hela was able to notice them too.

"Are you perhaps waiting for the others?" Kisuke Urahara asked curiously as he knew that the woman in front of him was a battle maniac so there was no way she would miss such a chance.

"Of course I am… I always love having odds, slaughtering everyone while being at odds never fails to give me pleasure" Hela answered with a grin and Urahara internally grimaced.

He was pretty sure that with the help of the others he could probably win but he wasn't sure if all of them would be able to come out alive or not and also have to protect the humans.

"Getsuga Tenshou!!" he heard a yell as a huge wave of blue Reiatsu was launched towards Hela. Kisuke Urahara almost felt like palming his face.

He just thought that they needed to protect humans and here someone just used a highly destructive attack. "Bakudo #81, Danku" Hela muttered and the Reiatsu attack was stopped by a translucent barrier.

"Looks like the party is here" Hela gushed out excitedly as she slashed down her sword towards Kisuke Urahara. Kisuke Urahara immediately moved away using Flash Step as he noticed that Hela was trying to replicate Getsuga Tenshou.

It wasn't perfect but the result was more than enough as a deep gash formed down the road. "This isn't strong enough" Hela muttered and the group of reinforcement finally arrived.

"Holy Arrow!" Ryuken Ishida exclaimed as she fired an arrow towards Hela. Hela simply tilted her head to dodge the arrow but to her surprise, the arrow exploded engulfing her whole body when the arrow was passing by the head.

"How strong is she?" Hirako Shinji asked hurriedly.

"She is strong. I don't know how strong exactly as was just playing around with me" Kisuke Urahara answered and Hela walked out of the dust cloud completely unharmed.

This seemed to surprise Ryuken Ishida as he had thought that his arrow would at least leave a scratch. "That wasn't nice but I am glad that you are thinking out of the box… all of you are going to need it" Hela said with a maniacal grin on her face.

"Why the fuck do we have to fight an insane bitch??!" a blond midget exclaimed rudely. The girl's name was Hiyori Sarugaki. Before anyone could even flinch Hela appeared beside the girl.

The girl only noticed Hela's presence when Hela's palm connected with the girl's cheek… tooth flew out of the girl's mouth as her body slammed on the ground creating a spider web on the ground.

"Little girls shouldn't insult their betters" Hela said with disdain and several people were already in the air as they lunged towards Hela with the intention of killing her.

Hela simply grabbed the face of the nearest attacker and slammed his face into the ground, creating a small crater. Hela simply dodged the rest of the attacks without any effort and pointed her palm towards the group.

"Hado #91, Senju Koten Taiho" Hela muttered and several purple orbs appeared beside her and were launched towards the group. A huge explosion erupted as the Hado connected with the group.

The flames engulfed almost a whole block causing small tremors in the area. "Tch… nice save" Hela clicked her tongue but she wasn't displeased as this was going to make the fight more interesting.

The group was saved when one of them had created a barrier named Koko no Jomon. The dust cloud was finally cleared by Urahara's attack. Hela slashed her Zanpakutou, cutting apart the attack.

Hela backstepped as a black-skinned woman slammed down her gauntlet-covered fist on the ground where Hela had been standing, forming a crater. Hela had an amused grin on her face as she lunged towards the woman wanting to slash down her Zanpakutou.

Hela was shocked to see that instead of going forward she had jumped backward. 'The Fuck?!' Hela screamed inside her mind but she was unable to contemplate over that matter as Kurosaki Isshin swung down his Zanpakutou.

"El Escudo" Hela muttered as a green barrier formed near her hand but her eyes grew wide when she felt Kurosaki Isshin's Zanpakutou cut into her side from the opposite side.

'How the hell is this happening?' Hela wondered as from the corner of her eyes she noticed a blind guy with an odd type of Zanpakutou rotating in his hand.

Hela noticed Kisuke Urahara approaching her with the intention of piercing her heart with his Zanpakutou but this time she was ready.

She knew that Urahara was coming from her back and she raised up her arm to defend herself but she was shocked to her core when Urahara's Zanpakutou pierced through her chest from the front…
