After having agreed to forming a alliance with Kabuto there was one favor that former right hand of the snake Sanin wanted from him. That is before he full handed over Rin to his control along with the six former demon holders, along with the extra trump card that he offer over for good measure.
There was something that Kabuto wanted the Minato's former student to take care of himself. That was well Kabuto knew that Naruto despite being among the ones that this whole entire war was about to protect in the first place along with Killer Bee. It was very clear to him that was not going to last very long as neither one of them seem to be the type to just sit back and let very one else doing all the fighting for him at all. Naruto would being joining this war it was not a matter of if but matter of when.
This would be just padding the deck for their side as even a 100, 000 Zetsu and army of zombie ninja might only be enough to slow the newly form Shinobi Alliance down. Most of the people in charge were though inspired by Naruto and they had quite of number of people that were when all on the same side together a true force to be recoken with.
Also Obito was interested because the target happened to be the a student of his old teammate Kakashi. That right as the one he was going after was none other then Sakura Haruno herself. True it was not easy getting her away from the Konoha as it was preparing for the Fourth Shinobi War he had just delcared on them. Yet Kabuto was not the only one that sneak around to the point where he was able to gather his Edo Tensei army without alerting the hidden villages that he had come across.
Using his time space justu he was able to get Sakura to lure the pink hair chunin into a trap. One were she did not even notice until it was too late as her experience with time space justu was her weakness at this point. After being draw into the Kamui dimension though she managed to dodge follow up attack that was meant to knock her out.
When she turned to try and attacked Obito she was shocked when her fist was blocked by wooden fist. That seem to absorb the charka she used in her charka enhanced punch Obito lift up her head so that he could use the Tsukuyomi. Trapped in this justu Obito planned to use to simply incapacitate her yet that would be as fun as what he thought of just then.
Sakura then looked as she noticed that her hand were changing into that of a puppet. She tried keep herself from panic telling herself that this was not real and that she just need to focus and that everything would be okay. She had looked into the Tsukuyomi, at least what she had managed to get from Tsunade on it as if she was going to help Naruto going after Sasuke it was possibly they would come across this move.
However all the focusing she did not however proved to be useless as she was rendered into nothing more then human sizer puppet that just stood there motionless staring vacant at nothing. Thinking this was over Obito was then shocked when someone actually mananged to harm him within his own Tsukuyomi. The words 内なるサクラ appeared on the forehead of the now puppet Sakura who moved was moving in mechanical motion with outstrenched fist.
That pretty much all she was capable of doing as the words vanished once Obito increase the power of his Tsukuyomi effect on her. Apparently in one last attack of rebelling Inner Sakura lashed out before become overpowered.
After canceling the Tsukuyomi, Obito stood looking at Sakura in reality who just stood there vacant eyes and motionless. The Haruno girl was now able to respond to anything as her mind was render into state where she was already nothing more then a puppet leaving half the job already done as after exiting his Kamui dimesion they appeared in recreation of one of Sasori's workshop where the man himself was waiting and eager to finally have his Sakura added to his collection.
