"I don't have a Zanpakuto or whatever you call it, just to let you know." Darwin stretches, warming up his muscles.
"That's strange. Aren't you a human? Hmm—" Zaraki looks at the green veins scattered around Darwin's neck and also his eyes neon green which seemed odd.
"Well it doesn't matter. I only look forward to the battle rather than their past history."
Hoping Zaraki's Zanpakuto to his left hand, he begins initating with a wide downward slash, cutting the air beneath its weight.
"Zaraki, I hope you don't take me lightly." Darwin releases his green gas, with a smidgen of Harribel's water techniques.
"Acid Cross!" Darwin waves his hand, forming a cross, he attacks with two thin acidic and high pressurised water blades.
The sounds behind this attack whips the air, funneling towards the downward swing.
Boom!
A thunderous exchange of powerful strikes.

—[Control Sector]—
"The alarms are on! Who is the intruder?!"
A woman dressed in an assassin attire, her flat chest and striking short hair makes her seem quite visibly striking compared to her authoritiative tone.
"Captain Soi Fon. There is a massive battle happening in Division 11th's Courtyard."
A member of a stealth squad, points at a projector projecting Division 11th's surveillance camera.
It's revealing an intense bout between an unknown individual with Kenpachi Zaraki.
"Knowing Zaraki's temperament, he would just see me as in the way. Tch—"
Soi Fon bites her nails in annoyance.
She then commanded her stealth squad, "Surround the courtyard but do not engage!"
"Yes Captain!" The stealth squads clad in black said affirmatively, moving with their Captain with great haste.

The acidic attack leaves a nice cut on Zaraki's chest. Using his Reiatsu, he pushes out the lingering acid residue eating away at his flesh.
"Not bad. Let's see how you react this."
Ring—g—g
The sounds of a bell ringing echoes within Darwin's sensitive ears.
"That's quite rude of you to use handicaps against me."
A swift stab launches behind Darwin's back, but Darwin reacts with a slight dodge.
He then uses Zaraki's miss as time to kick him on the head.
"Hoho~ This is getting good." Zaraki blocks the incoming kick with his wrist, sending him metres away.
"I hope you takes those bells off. You see… my ears are quite battle sensitive." Darwin mocks Zaraki by pointing to his ears with a light chuckle.
"I've never seen someone like you wanting their opponent to get stronger."
Zaraki smiles, his grin widens like a demon, showcasing an explosive Reiatsu.
'It feels like I'm a patience meter, measuring how much I could withstand the bullshit handicaps Zaraki is pulling.' Darwin sighed, feigning his enjoyment with this battle.
"Maybe you will show more of yourself if I did something like this."
Darwin spreads his arms out, unraveling green spheres in an array.
It's menacing numbers, power, transforms the very battle they are having.
Pointing towards the sky with his index finger, the gaseous cloud rises above the courtyard, spreading all over.
"Acid Rain." Darwin hurtles acidic spheres in quick succession, while maintaining acidic rain above for environmental advantage.
Feeling his skin peeling from the rain drops, Zaraki eyes were peeled onto the incoming barrage. He frantically swings at them with both hands, signalling a change in power dynamics.
The sounds of water cleaving was heard by the neighbouring stealth squad. They were awaiting next to Yachiru and Soi Fon.
"He is strong." Soi Fon admitted, having her eyes glued to the fight.
"I hope you don't join in to." Yachiru angrily stares at her, painting the picture that she wasn't the one to be belittled with.
"Hmph—" Soi Fon understands, her annoyed expression signalling that.
"I should respect you by taking off this eyepatch." Feeling weak from the outburst of attacks, Zaraki said with his hoarsed voice.
Snapping off the eyepatch, he grins.
The courtyard explodes with a mesmerising huge Reiatsu, the acidic rain dissipates, the neighbouring acid splurge across the ground disappears into thin air.
"I haven't used a sword before. Might as well improvise before obtaining my own Zanpakuto!" Darwin spreads his hands, revealing a solid green blade.
He imitates an unusual laid back stance, Darwin slouches forward leaving his blade swinging with a lessened grip.
Darwin's eyes slits, glowing more green on the edges.
'Is this how they control their roaring senses.' Darwin hisses out thick acid smoke, from his mouth.
Zaraki laughs, having the time of his life.
He dashes towards Darwin with supersonic speed gripping the hilt of his Zanpakuto with full power. But with Darwin's hyper focused senses, he reacts perfectly and lashes irregular, causing Zaraki to do the same.
The sound of steel clanging upon each other reverberates constantly with their intense exchange of blows.
The sparks flare up, the shockwaves emitting their exchange cuts the neighbouring walls with ease.
"This is getting to the good part. Hehehe—" Yachiru smiles in her crouched figure, swinging her head in joy.
"They are both battle crazed and insane dumbasses!" Soi Fon quietly mutters.
Their blades hit each other so fast, it felt like they were creating spheric mirage of different attack angles.
Darwin's eyes opens up, as he unleashes a devastating two-handed uppercut swing. Zaraki eyes also widens, his grin showing throughout the battle. He delivers a two-handed vertical swing, causing a massive and earsplitting thunderous clang.
"Hahaha! Zaraki, you have the same battle talent as me!" Both were engrossed, the rubbles lift and disperse in their wake, the ground and walls surrounding them shake.
Darwin's solely focusing on his sword combat is improving by each second.
Angles, patterns, muscle movements, he could see it all. He understands and adapts, making his swing more irregular and frantic.
With the battle growing more and more intense, their blades grazes each other skin without stopping.
Adrenaline waning in and pulsating through their blood boiling veins. The very air within their proximity screams of protest, moving outwards without stopping.
"Darwin! I wished I met you sooner!" Zaraki uses Kendo techniques he learnt unmotivatingly.
"Bissection!" The past downward, vertical slashes couldn't compare to this one. It was heavy, the after images of each motion arm joint Zaraki creates builds up a massive suction of air.
Darwin notices the intensity of this attack and chose to dodge with a deep graze on his left arm, letting it pass through onto the ground.
The courtyard splits, a massive crevice was formed in Seiretei from that one attack alone. The entire Seireitei notices it, squads all over came rushing towards the scene.
'Monster.' Darwin mimics Zaraki's curling grin not because he wanted to, but because his body compelled him to.
