Gaara watched everything unfold before him with a smile in his face.
'Ah how nostalgic.'
"This is command speaking. I am reminding everyone of their mission objective. Take care and await further instructions."
Their main goal in Konoha is to actually steal the corpses of powerful shinobi which will be used as chakra batteries after undergoing the process of edo tensei. The most sturdy walls come from these chakra batteries due to their unlimited amount of chakra. In truth the applications of these chakra batteries are as boundless as the stars above. Different shinobi yields to different kinds and qualities of chakra battery but of course those with great amount of chakra are the best batteries to have. A branch of Yggdrasil called Kamigami no Haka was built specifically for the purpose of aquiring as well as transporting these highly valued corpses from around the known ninja world and beyond.
However since he's already here he wouldn't let this once in a lifetime chance to rob Konohagakure blind of their jutsus. Kankuro and Temari who joined him as he left the coloseum became invisible as they approached the jutsu repository of Konohagakure located close to the Hokage Building. Gaara on the other hand sat on top of the tree waiting for a special deal.
'Here he comes.'
"What's the rush? Aren't you just looking for me?"
Gaara greeted Sasuke like a student who saw his classmate on his way to school.
"You! Is there a reason why you are attacking our village?"
Sasuke asked calmly.
"I'm hurt. Have you been perhaps attacked by a shinobi from the Hidden Sand?"
Gaara's response stumped Sasuke he immediately assumed that Suna is in on this coup without knowing exactly what is happening. It was mostly because his head is occupied with the questions and he wanted to extort answers from Gaara. Somehow.
"I know why you came. Go on. Ask away. I will humor your questions."
Sasuke was pleasantly stumped. Seeing the look in his face Gaara wanted to laugh at how foolish the shinobi world has been using their blessings.
"Tell me honestly what you knew of my family's massacre!"
Gaara pondered before making some hand signs for a whispering wind jutsu. His mouth began to open and close as if speaking but the voice can only be heard by Sasuke himself as if Gaara spoke directly from inside his head. What he is giving away after all are sensitive information that Danzo wouldn't want to be spread around lest his career meets its untimely end.
First, Gaara told him of how the Uchiha was treated in Konoha for a long time, then the planning for a coup, Itachi's choice, Danzo's manipulation, and finally the real reason why Uchiha Itachi massacre his entire family.
'For peace?'
"Is this for real?"
Sasuke saw the laughing devil mark on the back of Gaara's hand immediately snuffing out the blossoming thoughts of doubt in his mind. Looking for an avenue to burst in, he began to think back to the time when he was young and innocent. He did find many instances of isolation and bigotry against their clan, plus there were also instances where he heard some things that are supposed to be clan secret. Gaara's story was only solidified and not disaproved by his introspection.
Tears streamed down his face as he recalled the words of his brother.
Sasuke's eyes spun and his two tomoe sharingan evolved into a three tomoe due to all the anger inside him. This village that took his entire family from him. It took his happines. It basically killed him already in many sense of the word. He felt betrayed. Lied to. Manipulated.
'It's this village! I will destroy this village!'
"Tell me something. If I accepted your offer... are you willing to grant me enough strength in order to exact my vengeance upon this village?"
Sasuke was almost pleading at this rate because anywhere is better than here.
"Hahahahaha you make me laugh. Of course strength is a given what would I do with an incompetent retainer? But when it comes to destroying things the decision will lay upon your shoulder. If you are sure of your decision then come to me."
Sasuke came closer until he is within arm's reach from Gaara.
"This will hurt a bit."
Gaara then used his gear to absorb Sasuke's chakra to the point of exhaustion. The seal then activated and started to spread even with Kakashi's seal. Gaara then produced a chakra paper with fuin seals, something he prepared specifically with this scenario in mind. He placed it over the cursed seal of heaven and Sasuke winced in pain as the cursed seal was sucked into the paper. Gaara immediately threw the paper up into the sky before it burst in a spectacular explosion.
Gaara then transfered some of his chakra to Sasuke in order to hasten his recovery.
"Pray tell, where do you want your membership marking?"
Sasuke's eyes grew as wide as saucers.
"You..."
"Yes, you are correct. I'm a rather respected member of Yggdrasil. Enough to grant you membership at the very least. Come on anywhere is fine, we don't have all day."
Sasuke then stretched his tongue out and Gaara stamped the seal into the back of Sasuke's tongue.
"All right, welcome to Yggdrasil!"
"I will contact you soon about your extraction. I guess for now you can help your friends get rid of their pursuers."
Gaara showed Sasuke the display in his arm which showed the approaching team of Naruto followed by nine shinobi from Otogakure. Sasuke undesrtood that today would not be the best time to leave Konoha due to political implications it may cause and quickly left to help his 'friends'.
-------------------
In the main jutsu repository, no signs of struggle can be observed but the entire place is thoroughly ransacked by two invisible people while the guards lay asleep on the cold hard floor. The two separated to different directions as soon as their main objective is accomplished. They moved on to stealing from the ninja families and clans of Konoha. With the help of Gaara's previous surveilance of the entire Konoha including the main casts plus their gears the two invisible people are able to easily locate and rob from the private repositories of the major ninja families and clans.
--------------
On another part of the world Zabuza brought down his greatsword removing Haido's head from his body.
"Let's see you recover from that."
He kicked the body and sighed.
'Thought so.'
Crouching down, he pierced the corpse's abdomen with his barehands taking a green crystal from within. He looked towards his comrades who are currently freeing the children and securing the ship and nodded his head for now he can finally take that long trip home.
"Yo, its done. 120% I must say."
Gaara smiled, over the years he got to know this demon of the mist and could only say that the name assigned to his is wrong. He should have been named Mother Theresa or something.
[Oh? Planning to bring those kids along?]
"You know me all too well."
Zabuza the demon of the mist liked to pick up orphans on his way back from a mission. Gaara once asked why and he explained that he had only done the adoption thing with Haku due to circumstance. Now that he knew of a great place to bring them he wouldn't hesitate to help each and every one he saw. If and when they are willing of course.
[That is a given. Bring them to the Gelel base first when you arrive Mrs. Ayame and Karin will be in charge of them.]
"Roger that."
Zabuza cut the call and urged his subordinates to work faster so they can go back to base. He pondered what to bring for Haku. The girl is now grown so he figured something a girl her age preferred except he didn't know what girls her age preferred but he still deciided to go with the book about plants since she had this borderline obsession with the tree in Roran.
"This day just got better and better."
Gaara carefreely sat at the tree top watching the explosions going off from the distance, soon the border patrolls of Konoha will be informed and the tides of battle will take a 180 degree shift. He had to make a move before that as one more thing needs to be done before this can be considered 100% successful.
