This technique ,Shadow drive
Shikai gave it such name because it was the power of shadow , or lets say Sage state of shadow
and the character is that no physical attack can affect him, his body is like a shadow, no one can catch him , but if that person is 3 level above then the effect will be slowly decreased
with this in his mind the same characteristic was of Rogue from fairy tail so he gave the name Shadow drive
After having initial progress, that is knowing the ability shikai decided to fully and completely learn this because shikai want to be able to change into shadow drive when ever and for a long period of time
But how could this be performed without the proper knowledge so he decided to go to the 3 villages, slug, snake, and frog to know how they use Sage mode
and hence went to Tsunade
Shikai directly went to Tsunade's office always
here Tsunade was having a chat with Jiraiya who just returned bringing the news of Akatsuki
finding Jiraiya was good because to go to toad village he needs Jiraiya's help
Jiraiya "oh shikai why are you here?"
Tsunade too looked at shikai
shikai"well i need help of you 2 and Orochimaru , i will find Orochimaru and ask him but i need you two to help me "
Hearing Orochimaru , they were already unhappy but still listened
shikai"well , i know that Jiraiya an use something called sage mode and even the snake and slug have similar to it"
listening to this much already, Jiraiya said"well they have but you cannot learn without their permission"
shikai "i know , what i want is to know how to control that power because with continuous fight using shadow nature i now am able to feel shadow force affecting me making me strong but, i need a proper helper"
hearing this Jiraiya raised his eye because, even he don't know how to properly manage it so said"hmm, wait i will bring someone"
with this, he brought elder ma and pa of Frog
"after the topic of Shadow nature, they rejected Directly
"well we cannot help you because your nature is very much different than us , and completely different than snake too you should try Slug village, the elder there is the oldest so she might have some idea "with this they went
so shikai finally turned toward Tsunade
Tsunade didn't knew how to reply because she doesn't have sage power but decided to consult with her summon Katsuya
Katsuya after the talk with her elder agreed Shikai to visit their village so they formed temporary reverse summon.
Shikai after being reverse summoned finally threw out all he ate, reverse summon is a space system different from his shadow world, so there is a huge impact to him
after being summoned, all around him were greenery forest huge tree
and slugs everywhere
and in front of him was the biggest mountain he ever saw in this whole life
Shikai pointed toward the mountain and asked"Katsuya san , what is that mountain?"
Katsuya replied"oh!thats our elder"
shikai thought that the biggest creature might be Ten tail tree form but he was wrong , as the sore height of Elder was twice the ten tail
Shikai tried to sene power of elder slug but he was again shocked
because he could not sene the power of it , or simply say , elder was full of nature energy
Seeing the shocked Shikai, Katsuya walked toward the mountain
after arriving beneath of elder, shikai diretly jumped toward the top with a huge speed because there is where he found huge life energy
Seeing Shikai flying/jumping now it was Katsuya turn to be shocked
after flying for some 30 second he finally reached the top where he saw a humanoid figure there
seeing a humanoid figure , shikai was shocked and asked"hello lady, where is the elder slug , are you her attendant from the human world?"
listening to Shikai's question that lady gave her a light laugh but said" the elder you are looking is me "
Shikai had his jaw dropped
so Elder replied"well after gaining enough knowledge with huge life force and sage power, even a body can be made from it , so I am basically elder you are standing upon now"
shikai finally calmed down and said"sorry "
with this topic finally Shikai asked, well i heard from Katsuya that you know how to train shadow force. that the name i gave it"
Elder "well not that i know , i had seen someone training this force thousands of year ago when i was little and was traveling outer region"
shikai knew about the outer region she spoke of -it was like the force of Otsutsuki clan.
shikai" and what happened to that person?"
Elder "well , that man was just weak as your elite jounin and the elder of their clan . like you know our world is already a high level , but that place was low level. during my travel there with my sister , i learned about that nature " but later on we found that the planet was destroyed to its core "
since this news i hadn't gone out of here and now you are the second one to try that power, basically, that man died because he didn't have enough power in body to handle it but seeing you , you already have body being tempered for only that force "
to learn and completely make that force your own you will have to go deep, very deep to that world, and finally reach the deepest region where the test of power is carried out , there the world will force shadow nature into your body , if you can handle it, you will gain shadow force if not you will die "
