Prologue

The skies were dark with thick clouds. They had been threatening to rain all day. Classes had ended early, giving even more time to the long weekend. Big parties were planned but nothing had broken yet. The streets were lined with senior high schoolers walking to the store to procure what they needed to make it through the coming excitement. Ichigo had just finished meeting with some friends to grab alcohol for later, and at that time he was walking near Tokyo center in pouring rain. As Ichigo moved through the narrow streets, he saw a dealership with every kind of car, bike, and scooter imaginable were displayed, outside the shop and inside. It was a small dealership, secluded in the midst of alleys.

The dealership was dry and inviting, especially as the water came down harder than Ichigo had never seen before. A TV in the back showed a newscast about the sudden severity of the storm but how it was moving over the area quickly. As Ichigo looked around, though, it felt as if he was already in an oasis. The sleekest sports cars, the toughest trucks, the most advanced motorcycles... The best of the best were all around him, glittering in metal flake paint and chrome, in spinner hubcaps or classic models. There was a strange atmosphere around the place, a compelling one. It was almost electric.

Ichigo nodded sheepishly to one of the salespeople. Trying to duck away from the odd looks, he maneuvered into the back door in search of a bathroom to dry off in. The doors led to the garage behind the dealership. It was the end of the day, only a couple were present when he found something packed at the back. It was a motorcycle unlike anything he had ever seen before heavily customized. It was as long as a sedan, with dual thick tires on the front and and the black. The rider must be at least seven feet tall to comfortably ride it, he thought. There was chrome and a massive engine underneath

The sopping wet young man looked around almost guiltily before walking up to the bike and running a hand down its side. He shivered as if a chill had run down his spine. In reality it was due to his body losing heat at a rapid rate due to being so drenched. Still, he raised a leg over the side and straddled the beast hesitantly. It felt right, very right... and also very expensive. Ichigo could feel the massive engine beating underneath him, aching to be turned on. Still a he could dream, couldn't he?

Balancing the bike between his legs, Ichigo leaned forward and grabbed the half foot long handlebars. Ichigo had to stretch, having his chest touching the frame to make it there. However, he grunted in shock as thick viscous black liquid began to leak out, it was shining in the light. It drizzled down, filling in the countless veins, swirling about. Ichigo tried to let go his fingers from the handlebar, but the black goo shot out thick tendrils that wrapped around his wrist, coiling together, pulling him back. Ichigo was rather surprised how much like silk it felt. Despite being 'liquid' it didn't feel wet and caressed his digits, it flowed like a syrup but was as firm as plastic. In moments, the substances covered up to his upper arm, as if he had a leather sleeve.

"Help! Anyone" Ichigo yelled, but then the employee came. Ichigo looked at him, and he was odd. He had countless black piercings rising up their ears, nose and mouth, and his hair was unnaturally black. He looked at Ichigo smirking and smiling before suddenly fire engulfed the employee, burning him and killing him in front of him. "Fuck!"

From his shoulders, the substance pushed down towards his chest, sliding just enough across his pectorals. Straps of black rubber snapped across Ichigo's chest, coming together across his sternum. It looked almost like a leather harness for a moment before it dissolved the remaining of his uniform, coating his torso and back, coming together bit by bit as the last of his human flesh disappeared. The substance squeezed under Ichigo's belt, tendrils began to coil up the length of his manhood. The slick material caressed his length, sloshing and massaging it. It felt like thousands of tiny hands were working it up and down, and with each beat of his heart, it filled out fuller underneath the substance.

A moan escaped his lips, involuntary at first, but then voluntary. He even started to move his hips forward and back, as if thrusting into the invisible grip of the alien intruder. Ichigo blushed, unable to help himself, and he was getting hornier by the second. He wanted to be afraid but it felt so good.

{Rider...} A feminine voice shuddered, he was not fighting it anymore. He was embracing it.

The black substance continued its decline, covering his knees, his ankles, and finally his feet. It swept down over the heel and the toes, before the whole substance turned into one of the finest in Japanese riding leathers. Form fitting with intricate patterns. There were elements of metal on the gloves, pockets, in various places. The outfit looked as though it was part of the bike.

Once fully covered from his neck and down, the black energy was spreading into him - and it felt amazing. The black from the center of his eyes spilled out, covering the orbs completely. His saliva darkened and the veins in his neck started to darken as well. Ichigo could feel his motorcycle in his head, how playful, tough and horny she was, and how much it loved being used. The feeling was infectious. Ichigo moaned again, his lips parting as his canine teeth stretched out into fangs.

"Venganza..." Ichigo smirked at her name.

As he spoke her name, a sudden change happened, he thought the suit was shrinking, but the truth was quite the opposite: He was growing. It started in his stomach, at first it started to gently ripple as more bumps started forming. Rows of abdominal muscles filled in, segmented down the middle and in-between. The leather jacket cupped on each muscle and contoured it. Even Ichigo's diaphragm was changing, growing stronger, forcing the teenager to draw in more breath. His chest filled with air and exhaled, filled with more air and exhaled again, but each exhale only brought the chest down a portion of how much it had grown…

{Grow, my Rider} the feminine voice moaned.

Ichigo grunted as he felt the flesh rippling and changing beneath his hands. His biceps started to swell out, rounding, getting creases and bulges in all the right places. A moment later his triceps followed suit as his arms thickened. His forearms gained more meat, even his wrists were covered with brand new sinews of muscles before his fingers stretched out straight, his hand feeling as if it was being dipped in lava. He involuntarily flexed his fingers as the knuckles popped and the fingers stretched longer, the fingernails stretching out in the leather before they emerged as black claws. The handlebars were now fit for his size.

However, it was not done, Ichigo screamed out as a fire burned through his spine, his back arching. Drool leaked from his lips as his vertebra swelled, nubs pushing through the skin of his back… but they weren't just pushing toward the surface, they were growing… and they were growing more. Ichigo lifted his head toward the ceiling and let out a howl of pain as his spine stretched longer.

"Rrrrrr…" The roar was loud and harsh, Ichigo's thick saliva running down his fangs as they stretched out longer, as the bottom stretched up to be equally menacing.

As Ichigo's spine stretched, his ribs moved apart again. His torso was growing longer, inch by inch. Ichigo's new grown form made it easy to fit his motorcycle. Ichigo basked in the pleasure of his form, his strength and flexibility and size. The pain was still keen on his mind, but the pleasure was so much more as well.

"Give... me... more...!" "Take me over completely..." Ichigo whispered, waiting, "GIVE ME MORE!" He howled before he tipped his head back, gasping in bliss, roaring when he felt the fire of hell.

Suddenly the hell fire was burning inside him. His eyes began to burn when they were engulfed in flames. His head bulge and shift, the skin trying to hold something back before thick ribbed horns broke through. The horns pushed out and up from his head like double swords being unsheathed. They curved back along his skull before curling around, the tips ringing his ears before aiming forward again.

Ichigo snarled with pleasure, showing off his sharp fangs. Ichigo's blood was boiling... so much heat out of nothing when suddenly flames engulfed his head, burning off all skin and showing off a horned skull with fangs. Ichigo twisted the handlebar and then fire and flames emerged from the four wheels. Ichigo crushed the local and moved towards the roads, there was so much to do. Ichigo knew he was not from this realm, he had to burn his past away and embrace his future as the Rider.

{Punish them, burn them} Venganza yelled inside him as Ichigo felt how hungry she was and how horny she was.

Ichigo groaned as new knowledge flooded his mind. Every curve of the road was his new delight, and the Venganza was his loyal steed.

Vengeance had turned him into an Arrancar, but he was truly not alone, he was a special one. The amount of energy he transmitted on the bonding sure was felt by the Soul Society and a certain fellow.
