It all started when Ichigo while sleeping late at night heard a female voice calling to him repeatedly to come to her and at first thought it was a dream nothing more.

That is until he awoke.

Wh…what!?' Ichigo nearly screamed in shock as he realized that was in the middle of a street, his body walking on his own, and when he tried to move against it. He realized that he had no control over his own body. With all of his limbs being forcibly controlled by what he could only describe as threads.

"The Hell!?" He tried to scream out yet even that sense of freedom was robbed of him and when he tried to break out of the threads by channeling his Spiritual energy, it felt like some poison was coursing through his entire body that somehow prevented that and combined with the fact that he doesn't have access to his badge, his Spiritual powers are also too limited to fight off both the poison and the magical threads that were controlling him.

Eventually, after forty minutes of nonstop walking through the forest and up a long stone stairway through a huge forest. The substitute soul reaper arrived at a great Shinto temple up in the mountains.

Then upon entering through the gate and into the courtyard the one who cast the spell and inserted the poison appeared in front of him, a young sorcerers draped in blue and purple robes while hiding the top half of her face with a hood with golden outlines and a gold insignia of a small mage.

Which Ichigo immediately recognizes as the Servant Caster.

"Well now…" she spoke in a charming yet deceptive tone. "I knew that it wouldn't be possible to control you shinigmai like humans. Given your enormous reserves of spiritual power" she then chucked a bit…"But given that you Kurosaki have willingly decided to sleep in your human form it was child's play to me"

Ichigo then growled In frustration. "What do you want!?"

Caster then gave a mischievous smile. "Oh, many things, such as finding out what makes you Shinigmai so powerful, your reasons for participating in the Holy grail, the secrets of your zanpakuto I but most of all…' her smile then sinister. "To break you down and turn you into my test subject"

Ichigo then cracked a smile. 'Your…test subject!?" He spat out distasteful. "Lady look, you can't just -ack!?' Ichigo suddenly stopped himself when both of his hands began to strangle his throat while the caster's expression was one of disapproval.

"It seems you don't understand the situation that you are in child," she said coldly. "Whatever choice you have means nothing when I have full control over your body and if I so wish it, I can use you to turn against your friends, your family…or even the lives of the innocents if I so wish" she explained in a sadistic whisper.

Ichigo's heart then began to beat in panic. "You…you wouldn't" He nearly screamed out but this merely made the servant chuckle a little bit.

"What makes you think I that I won't? For after all Kurosaki…" Caster then with a gesture had Ichigo let go of his hands around his neck. Allowing the captive man to finally breathe as he desperately gasped for much-needed air. While devious Mangus walked behind him and gently lifted his hair. "What better way to torment and break someone like you into a proper test subject... than by making you feel utterly powerless before my will?"

Ichigo wanted to talk back to her. To say to go to Hell or anything to express his defiance. But her spell had such a hold over his body that even that was impossible to do. This means that the only way out of this was to either keep pumping Spiritual into his human form at the risk of crippling it…or Caster becomes careless and kills his human body to free access his shinigami form and break out of her thread"

"And if you think that any of your friends are going to save you well…" Caster paused and Ichigo's further dilated in horror. "Let's just say they are preoccupied at the moment"

Meanwhile, at the suite, Ichigo's friends were busy fighting against an army of skeletal warriors that looked like they were made out of dragon teeth, as they rose from the ground in black-purple mist, and while they were not all that challenging to take out in a single hit. The undead abominations just keep coming with no end in sight.

'Damn it!' Renji shouted in frustration as he cut down more of the skeletal warriors with a single slash of his zanpaktou. 'There is no end to them!'

Uryu then shot several arrows at the skeletal warriors. 'And given that they appeared shortly after Ichigo went missing they are oblivious and sent here to keep us occupied by a servant"

Rukia stuck down several more of the skeletons with her zanpaktou. "Which means one of us has to make an opening to escape this hoard and rescue Ichigo" she concluded…and then realized something was amiss. "Wait where is Urahara?"

Sado now fully recovered obliterated dozens of warriors at once in a single punch. "Seems he is already on it"

Meanwhile at the temple. Caster immediately jumped out of the way from a beam of red energy and when she looked up. The launcher of the attack revealed himself as Kisuke Urahara, with the bottom of his wooden cane smoking.

"Seems I finally made it," Kisuke said cheerfully. Ichigo looked at them in surprise yet relief, while Caster gave an expression of bemusement.

"How curious…" the servant commented. "I honestly didn't think that one of your associates would have been able to escape my dragon tooth warriors or even able to find this place so quickly"

Kisuke then smiled before tilting his bucket hat down. "I honestly don't know if you are being sincere or acting oblivious," he said in a playful yet serious tone. "After all one doesn't need to be an expert to suspect that a servant especially those of the Caster class uses magical threads to control someone several kilometers away and track them to their source" He then knitted his brow at the caster " And that is ignoring the strong boundary field around the whole mountain"

"Hmpf…" Caster let out a playful smile. 'I suppose that it was rather obvious but still…that doesn't explain how you got past my servant"

The shopkeeper then grinned. "Well… let's just say I struck a deal with an old sentence"

Standing below the steps of the Ryuudou temple stood a young samurai warrior, with long purple hair tied in a pony and dressed in a purple kimono with a white undershirt underneath standing was a Strange Shinigami captain, with a black and white mask-like face, with a main of blue hair curled in fancy strains and white hands with extend finger-like extensions and beside him a young woman with dark purple hair tied in a bun.

For they were Mayuri Kurotsuchi and his lieutenant and artificial daughter Nemu Kustsuchi.

"Well, this quite an intriguing situation…" Mayuri spoke in a low yet screeching voice. "Usually I don't associate myself with the likes of Kisuke Urahara" the captain commented and then grinned viciously at the Samerai before him. "But it would rather foolish to turn an opportunity to experiment on a heroic spirit"

The young samurai then stared at the captain and gave him a calm smile. 'I am afraid I not what one would call…a proper Servant"

"Oh?' Mayuri spoke up intrigued. "Well if that is the case then that just makes me want to capture you all the more" He declared boastfully. While the Servant remains nonstop.

'And I hope you are aware that I am not a prey that can be so captured Shinigmai" the man countered and in an instant, he lunged at the captain who immediately drew his zanpaktou and blocked the strike and before long the Shinigami Captain and heroic spirit engaged in battle.

Meanwhile, at the temple courtyard, Caster then stared down at Kisuke. Ichigo tried to grab his substitute badge in his pocket but cursed himself when he found it missing.

"Perhaps we can agree Shinigami?" Caster spoke up and Kisuke narrowed his eyes.

"That seems mighty bold of you considering you had just kidnapped one of my comrades..." Kisuke countered cheekily and then his voice lowered. "Still what exactly are you offering?"

Caster then gestured up her hand. "An avoidance of unneeded violence of course" she argued. "After all I know full well of what the true nature of what the Holy war grail is and what is needed to fully manifest its power"

Ichigo then eyed her uneasily while Kisuke narrowed his eyes on the Servent.

"And that is?" The older Shinigami asked

"That in order use the holy grail all seven servants that have been summoned to this war must be Sacrifice and all their essence is stored within the vessel that is the lesser grail which is then used to empower the greater grail" she explains. "However since I am one of the seven heroic spirits summoned it is practically impossible for me to achieve the holy grail in such a way...unless certain preparations are made"

Ichigo squinted his eyes in confusion. 'All seven servents?' He questions in complete loss. 'But I thought the original holy grail was a battle royal in which the last one standing would be the master and servant' he then furrowed his brow while remaining focused on Caster. 'Yet she somehow found a way to get the grail without killing any of the servants?

Kisuke's eyes then darken grimly. "Preparations that involve Ichigo here" the man deducted.

Caster smirked. "Not necessary...but a sacrifice nonetheless to grant my wish"

Kisuke then raised his eyebrows slightly. "Which is?"

Caster then smiled though this time much more softly. "To indefinitely stay in this world...for my reasons"

Ichigo and Kisuke then expressed surprise at the humble revelation of the wish.

Kisuke then lowered his hat over his head. "I will admit that does seem like a rather reasonable proposition...however" he then stared directly into the caster's eyes. " I cannot let you sacrifice an innocent just to satisfy your wants"

Caster then chuckled. "Even if that innocent is a master within this very war?" She questions the man in front of her. "And one that you will likely kill regardless?"

Kisuke narrowed his eyes and stayed silent for a moment and then answered. "As far as I am aware the Shingami are only assigned to slay the servants, not their human masters unless given no choice" his voice deepened to the point of threatening. "And as far as I am concerned this innocent did nothing to deserve to be turned into your living experience"

Caster then looked at the shinigami for a few brief seconds before sighing in dismay. "How disappointing...and to think we could have a mutually beneficial alliance"

The heroic Spirt then steadily rose into the air and fully unveiled her cape, revealing in her right hand a large staff with the top having a large crescent-like circle with a smaller crescent circle within on the upper left side. Attached to a much smaller circle at the bottom. Underneath her cape revealed glowing butterfly-like markings with the inner ones glowing a dark purple, the mid ones glowing a light violet, and the outer ones making the edge of the cape a brilliant orange.

'Still, it is assuming that a mere associate like you honestly thinks they can stand against me alone"

Kisuke then chucked while folding his hat under his face. "I will admit I am a rather humble shopkeeper who rather just sticks to the sidelines…however"

He then raised his cane and pointed it at Caster.

"It would be unwise to take me lightly"

He then waved his cane towards the left.

"Awaken Benihime!"

Caster looked on intrigued as the cane glowed red before transforming into a medium-sized sword, with a decorative belt with brown beads dangling from it and a bent pummel with a red tassel on its end.

Then before the Servent's eyes, the Shinigami disappeared and instantly reappeared behind her much to her shock.

'His fast!' she then immediately raised her hand to form a barrier.

But by then it was too late.

"Nake Benihime!" Urahara roared out and from the edge of his blade, a huge wave of red spiritual energy shot out down at Caster.

The crimson blast burned through her body vertically in half. While let out a horrified scream as she felt her very flesh and bones burnt to ash and a second later the rest of the Servent's form was vaporized. Then when the energy wave hit the ground it turned into a huge explosion with enough force to shake the entire mountain and when the dust finally settled it revealed a large and deep crevice in the ground.

However, Caster then reappeared on the other side of the courtyard none the worse for wear.

"Impressive…" She complimented before rising into the air once more and spreading out her cloak. "But let's see how you will handle this!"

Then near Caster, over six purple circles of magical energy appeared near her and Kisuke adjusted his stance.

In an instant, all of the circles shot out beams of matching light which Urahara countered by raising his zanpaktou

'Cry Chikasumi no Tate!' And in less than a second a blood-red hexagon shield materialized in front of Urhara and Ichigo. Yet the sheer power behind the barrage of the rays of light was so great that they cracked and nearly broke the shield apart. Much to Kisuke's surprise and concern.

'That magecraft spell is much more powerful than the norm' Urahara commented and procceded to analyzed the rays of light that damaged his shield. 'To the point that just one of those beams has power equivalent to that of an eighty level had…' When the barrage ended he then disabled his shield. 'Which means only one thing…'

"So…' Urahara spoke out. 'I can guess that you are you are a heroic spirit who has come from the age of gods. Considering that you can cast greater magecraft without even needing to speak an incantation or name through the use of Divine worlds?"

Caster then chuckled. "Well of course'" she confirmed. "Compared to the modern magi of this area their works while solid are like mere sand castles that are washed away by the power of my magecraft" She then smirked. "Even your magic, Kido was it? Can't even stand up to my power!"

Kisuke then hummed. "Is that so?" He challenged. "Well I can only hope you can back it up"

The Shinigami then turned his gaze towards Ichigo. "I suggest that you stay out of the eay or try to retreat Kurosaki" he warns. "Because given how powerful this Servent is I don't think I can protect you and fight her at the same time"

Ichigo then gave an agitated look but sighed in understanding. "Right…I be sure to get my badge and join up with you as soon as I can!" Ichigo begins to run out the door of the temple.

But then a group of dragon tooth warriors suddenly surrounded him.

"Oh come now, you don't I will allow you to easily escape right?' the caster said smugly. But her expression turns to surprise when Ichigo proceeds to use his marital skills to smash down the dragon tooth warriors with ease and eventually escapes through the gate.

"It seems you underestimated Ichigo's determination even without his powers'" Kisuke taunted Caster whose expression turned from slight irritation to back to smug confidence.

"No matter…once my Servent and I finish with you two shinigami, I will be back to claim him"

Urahara then gave his opponent a knowing smile. "And as I say again…" he then got into a battle stance. "Neither I nor my associates are people to be underestimated"
