Kenji " I would need to up my Knowledge and training for a while. " Kenji took Obito's hand and gave it to Rin. Kenji " Rin, My brother will be in your Care. In this world for him after Grandma, you are the person he cares for the most and he would turn the entire world upside down for you. Please take care of him, in case something happened to me. "
Obito was shocked, he never imagined Kenji knew and what made him paralyse was he told it to Rin Directly. Rin wanted to say something but unable to say it. Kenji " I trust you with my Brother. " As he said he formed a Seal and gave a duplicate Key or Seal to Obito inscribed in his Hand and it disappeared. Kenji " It is the key to the Hidden Leaf and the Skypiea. I entrust you this in case anything happens to me. "
Obito " Kenji... " He clenched his Fists. Kenji '' Obito, I will not leave immediately and I don't want anyone to knew about it. My absence will be barely noticed. " He then left the trio of Obito, Rin and Kakashi. Each thinking about what happened around them, right now and still Rin holding Obito's hands. They are barely 7 years old but they are already precocious and mentally mature.
Obito " No need to worry, Kenji will return safe and sound without any problem. " Kakashi smiled and so as Rin. Suddenly Rin and Obito saw each other and still Obito's hand is with Rin. Obito felt heat raising to his head, took his Hand and ran away '' I got to train!! " Rin can't help but think about Obito all the time she knew her. Rin had a thought ' May be I have always expecting the wrong person to love me. ' she smiled thinking about Obito's silly smile when he saw her.
Kenji meanwhile started his Project of Ki Gathering Array and learn several of Sealing Jutsu to the Jinchuriki Level. The Sealing Jutsu would be his Ultimate Trump Card in the Dragon Ball World. He could have them and have his power increase. Kenji also started polishing his Martial Arts that have some elements of Dai's Leaf Taijutsu. And Flowing Water Stream Shattering Rock Fist. He removed some of the Martial Arts. His Martial Arts are evolving
Kenji meanwhile awakened a Bending Style Fighting mode in his Sage Mode. He can do Shape and Nature Transformation of Chakra around him, the farther the Nature Chakra around him, more Concentration requires and it becomes Difficult for him. He does not need Hand Seals with his Dual Mind Technique for doing the work of Hand Seals.

His fighting style resembles Fighters in Teken were each of his Punches and Kicks empowered by the Lightning. He incorporates the Five Breathing Total Concentration Modes of Different Natures. And he is training the seamless switch of different modes.

The Array has been built, Kenji Kickstarted the Array with his Nature Energy as starter and the later the Collected Nature Energy would work like a perpetual Machine to gather and concentrate on it. Slowly Kenji felt the Nature Energy Concentration increasing.

Kenji due to his Training unable to form Ki during these times but he learned the Dancing Sky Art with Nature Energy. Kenji had stopped utilising Chakra and completely devoted his Body to Nature Energy and started utilising only the Nature Energy. Meanwhile on the Hidden Leaf side, there has been unrest in the Ninja Villages.
Many powerful Ninjas of Hidden Leaf are missing and whereabouts or intel is missing for the Great Ninja Villages. It has brought unrest to the Villages. Meanwhile Hidden Sand Village are said to have their Ninja Army are mobilised at the Border of Land of Wind. The world is on a brink of Ninja War. Only reason it did not start yet is a single Fuse. Where last time the White Fang commited Sucide and the Village Power decreased significantly. But this time the Sand Village is waiting for the Opportunity to strike.
Kenji found out that the Sealing Techniques has the power to devour the Bloodline Limit provided they are stronger than the Target. The Downside is it is a slow and time consuming process. It is similar to Roshi the Four Tails Jinchuriki has Lava Release due to the Chakra of Four Tails Chakra. gradually changing the Bloodline of Roshi. He can do the same as Hashirama's Cells to other Targets as long as he can devour the Cells of the sealed target.
Kenji learned the Sealing formula and the sealing method, another 3 months passed, now the atmosphere of Skypiea is a heavens gifted land for Training, the Skypiea has become the one of the Powerful Hub for fighters. Occasionally some Pirates did appear to Skypiea by the path of Summit High West.

During this time Kenji had placed many Psychic Seeds to slowly influence people from Ninja World and One Piece World to have Loyalty towards him. Especially the Root. Meanwhile in Birka, Enel was discovered by Orochimaru, to expected to have extraordinary Talent in Haki and Science.
He is currently training under him. Kenji also passed tried passing Chakra, but it did not work on the Natives of One Piece World. Or to be more precise, not enough Chakra to do the same. But by Breathing Method, the Development of Haki and Physique surpassed the Scope of Marine Six Styles. Enel, Wyper, Raki, Ohm some of them are future potentials who showed astounding Talent.
Now the Skypiea team of Ninja World is a top notch higher than the Elites of the Other Ninja Villages of the same age. As there is a chance of War increases, Kenji had let the new team rotate to the Skypiea, And the old teams present were sent to the Ninja World to defend the Leaf Village.
