With that Tsubasa removed the gun from her face, returned it to its holster and then offered her a hand up instead, "Very well, then the Quinto Espada shall join the Gotei 13. This thing does not intend to make the arrancar a pet or a slave. But it will make sure the arrancar does not betray the shinigami." After helping Thea up Tsubasa would pull his zanpakutou from his sheath and open up a senkaimon. [color=jade]"The other shinigami must not know the Thea is an arrancar until this thing can explain the situation. Wear this." He took out the cloak he had on before and offered it the Thea. It would weaken her further but it would also hide her reiatsu and with the hood up her mask should be hard to see.

~Of To The Lab~

Assuming the arrancar was compliant Tsubasa would escort her through the senkaimon and to the 12th division barracks. He would show her to a room she would have all to herself before parting with a stern warning, "This will take time, this thing has never performed this task before. Don't let other shinigami know an espada here yet, keep that cloak on. This things shall return when it is ready to begin the experiment."

With that Tsubasa would head off to the lab in order to perform some simulations as he thought up both a way to give the arrancar the ability to use kidou as well as a way to ensure she did not betray her oath of loyalty.

Thea nodded in reply knowing she had just betrayed her kin and the Ancient One, she let out a sigh as her eyes fell closed for a moments time, afterwards she opened her eyes and put on the robe the hood itself overshadowing her visage as she followed The Shinigami through the Sekaimon.

-Later in the Lab.-

She heard him speak of a room and she looked to it, walking in and sitting there, her silence proud and strong with no such a will to conversate, she was disappointed in herself but perhaps it was for the best..

It would be a painfully long 3 days before Tsubasa was ready. Lots of time for the Espada to change her mind. Tsubasa admittedly feared her betrayal as a very real possibility and so he worked as quickly as he could. The simulations were done in a day as well as the modifications to the Zero System however to produce what the simulations called for is what took the most time. But in a simple 2 days the 12th division captain succeeded in bio-engineering the creature that would be capable of helping Thea attain her desired goal of learning kidou.

He would make his way to her room and open the door looking absolutely dreadful. The sleep under his eyes made it clear he was pulling all nighters in order to get the job done as fast as possible. If Thea was still in the room and she was still willing to go through with things he would say the awaited words, "It's ready." He would go on to explain both the Eikonmaku as well as the Evil Eye System. He would tell the Espada how they worked, what their limitations are, and was very clear on the restrictions. He told her the truth and made it a point to look her in the eyes while doing so.

If Thea still wanted to go through with it he would then lead her to the lab ensuring that her cloak remained on. Once in his private lab Tsubasa would have Thea lay on the operating table in order to begin the procedure. It would take a grueling 4 hours during which time Thea would be put under using anesthetics. At last after 3 days of waiting the deed would be done. Tsubasa would patch Thea up and wait for her to awaken in order to see if the results were a success. Upon waking he would simply tell her the following, "Careful now, Thea will take time to recover from the surgery. But for now she should feel something odd inside of her. That is the Eikonmaku. Feed it some reiatsu, just a little, and then build up your reiryoku. Tell me if you sense the difference."

Thea was sitting in the room in the cold darkness, nothing but the cold touch of the air hitting her hierro induced skin she could hear foot steps and her head turned to view the door one of her eyes peeking from the shadow that was casted by the cloak's hood, as the door opened which gave way to the light of the facility she saw the captain seeing clearly he had not a wink of sleep.

Hearing him speak she stood up and nodded following him towards the private lab on her way there she eyed many shinigami of the captain's division, finally they entered the lab and she removed the cloak and laid on the operating table, after four long hours of surgery she woke up feeling a bit weak but she heard his voice telling her to fuel Eikonmaku with reiryoku to create reiatsu, perhaps this was the method needed to learn kido and so she did, as she focused her reiryoku her stomach seemed to toss and churn as something inside of her slithered about she felt a snap in her cerebellum like she had learned a new part of herself and for the first time in a long while, her eyes widened..It had been done.
