Reborn in bleach as a hollow with a system

A senkaimon appeared and opened its doors revealing two Shinigami, a rough looking red haired guy with unique eyebrows and a refined black haired pretty boy walking out.

The rough looking guy flipped down a set of goggles and started scanning the surroundings.

"I found some traces captain Kuchiki." he says to the pretty boy who barely nods and remains silent.

Hisashi was camouflaged on a nearby building roof looking down at them. He had noticed the fluctuations from senkaimon portal forming.

'Gotcha!' Hisashi thought spying on their arrival to Earth.

He had been keeping an eye on the area along with the Ichigo and Rukia duo for the past few weeks waiting for these two to appear. Ichigo had driven off the Gillian just the other day so he knew it was close. He managed to take advantage and hunt a bunch of Hollow covertly during the outbreak, but made sure to stay on the sidelines during the grand event.

Hisashi stalked the two as they scouted around town until they got to the Kurosaki Clinic with Rukia running away.

"Kuchiki Rukia, we've found you." the rough looking one said with a smirk.

After chasing her for a while unnoticed the rough looking one yelled at her from atop a power line pole. He lunges towards her almost slicing her in two head to toe with his zanpakuto and crushing the pavement, she barely manages to back away in time.

"We've been following you the whole time and you were so caught up in your thoughts that you didn't even notice us until I called out your name. Granted you're stuck in a gigai, but haven't you become a bit too lax?" he asks her arrogantly.

[Gigai]

[An artificially created physical body that can be possessed by spiritual beings to interact with regular humans.]

"Renji?!" she says not knowing what to say.

"Answer me, Rukia. Where is the human that took your powers?" he questions her.

"What are you talking about? Just because I'm in a Gigai doesn't mean I've lost my powers. Also, how can you say it was a human?" she denies.

"It was a human! Otherwise how come you are behaving so human?" he answers confidently.

Rukia backs away her eyes wide in shock.

"We grew up in the same place. You were adopted by the esteemed Kuchiki family. Right?!? You're Kuchiki Rukia! You shouldn't be looking so human!" he practically growls at her in indignation.

"Right, captain Kuchiki?" he asks looking behind her.

Rukia turns around slowly in fear of what she will find only to see the refined pretty boy.

"Brother...Byakuya." she barely manages to say,

"Rukia..." Byakuya says unemotionally.

Before he says more Renji dashes towards Rukia and attempts to slash her again barely nicking her cheek causing it to bleed.

"Passing Shinigami powers to a human is a serious crime." Renji reminds her.

"Now tell us where he is." he demands from Rukia.

"We'll take you back and kill him." he finishes while preparing to strike again.

Rukia backs away from him slowly. He slashes at her diagonally which she dodges by jumping over it. She only manages to dodge his follow-up strike by rolling back on the ground though before jumping back up on her feet. She's already running out of strength though and stumbles to her knees.

Renji walks up to her to finish her, but is interrupted by a spirit arrow he has to dodge at the last second. A black haired bespectacled guy sharp eyes and bandaged hands carrying a shopping bag walks into the light of a street lamp.

"Two armed men attacking a girl. How unpleasant." he said as he walked up to them.

"You can see us? Just who are you?" Renji demands of him.

"Just a classmate..." the guy in glasses answered him nonchalantly while pushing up his glasses.

"...one who hates Shinigami." he completed the sentence.

"Why are you here?" Rukia got up and asked him.

"Just a coincidence, don't worry about it." he told her.

"It's not like I sensed Shinigami and came to take a look with this shopping bag as an excuse." he said.

Renji slashed the shopping back to pieces.

"I asked you who you were." he said being annoyed at being ignored.

"Well don't answer if you don't want to. I'll just kill you." he said pointing his zanpakuto at Uryu.

"Wait, he has nothing to do with this!" said Rukia and quickly rushed in front of the guy with glasses to protect him.

"Didn't I just say I'm her classmate that hates Shinigami?" the guy with glasses answered just as arrogantly as Renji had been.

"That's not an answer!" Renji yelled back at him.

"Ishida Uryu. Pleased to meet you." he said calmly.

"What's with this attitude?" Renji asked.

"You'd still want to know your killers name, wouldn't you? Uryu said.

Renji's hand started shaking in anger, a slightly deranged smile appearing on his face.

"I've decided. I'm going to kill you!" he said.

Uryu manages to fire off a few more spirit arrow which Renji blocks one by one using his zanpakuto while slowly closing in on him. After a few moments he manages to get in range and stabs Uryu in the stomach. Uryu collapses on the ground as he bleeds out of the stomach wound struggling to get back up.

"Renji Abarai, that's the name of the man who killed you." he told Uryu looking down on him before slashing his zanpakuto down.

"Wait!" Rukia screamed.

Suddenly a giant sword slashes between the two blocking Renji's strike and splitting the pavement leaving him no option, but to jump back away from a Shinigami with bright orange spiky hair and the biggest zanpakuto he has seen.

"Which squad are you from? W-What's with that big ass z-zanpakuto?" he questioned the newcomer.

'Well Ichigo finally made it here. Just in time as is his style.' Hisashi thought to himself as he watched the fight happen.

"Oh? So it's big after all. I did think it was big compared to Rukia's." Ichigo said.

"The size reflects the Shinigami's spirit power." Renji revealed to him while thinking about what this means. Suddenly his eyes widen in realisation.

"I see. You're the one that stole Rukia's powers!"

He jumps at him slashing like a madman which Ichigo repeatedly blocks.

"What's the matter? Is that big sword just for show?" he taunts him.

Ichigo finally takes a wide swing at Renji, however Renji jumps past the blade and with a spin slashes him from behind on his shoulder incapacitating him.

Rukia wants to run towards him, but is stopped by Uryu who is struggling to grab her ankle.

"It's over. You'll die and Rukia will get her powers back. Then we're taking her back to Soul Society where she will die." Renji says.

"You're such an idiot, she ran away all the way here so you wouldn't be involved, but you just had to come after her. Did you think you could do something? You...an accidental Shinigami? You can't even scratch a real Shinigami like us." he mocks Ichigo.
