Ketsu in Kaku, Starting in Kaku clan to Ketsuryugan at the Ninja World

Laying on the dry earth floor of a rock mount in the nearby of the biggest port city in the south of "lightning no country" was a strange corpse-looking figure.

A small "mummy" of a boy, looking like he fell backward with his pants on his knees and a pile of indescribable dry "mud" in the middle of where he was standing before.

Suddenly, the cloudy coastal sky started to darken, a storm approached, and the gathered clouds started to condensate and rain over the dry scorched land.

As the abrased soil soaked, the boy's body got covered in raindrops, and the pile of dry fecal matter started to be washed away, revealing inside it many things that would kill most mammals that aren't goats if eaten.

Suddenly the most common natural phenomenon of those lands started to make his presence known, a thunderstorm full of Lightning bolts with a strangely fast gathering speed uncommon in any other part of the world.

Then, as if something or someone attracted it, a bolt of lightning larger than a Chinese/Japanese wooden medieval bucket/bowl hit the pile of indescribable stuff nearly hitting the boy's legs and cleansing it from existing.

As if in pity for the child's fate, arcs of electricity from the beam covered his body and made him spasm, his heart started to beat again and the water from the rain started to be absorbed by his steaming skin, his dehydrated body slowly recovered to a healthier looking state.

As the storm continued, the kid contracted his face from the light and sound stimulation and opened his eyes, looking dizzy, and tried to move, but failed due to his previous circumstances.

Slowly recovering his body movement, or better his new body movements the boy started a journey in a few years of the body's memories.

His mother, not the mother of his body named herself Hana but told the BPO her name was Kamakaku since she was born with a scythe-like black horn, and her father's name was Raikaku also alluding to his horn.

Both of them are members of an infamous lightning country ninja family who ended after the family leaders Kin and Gin-kaku assassinated the second Raikage and Hokage leading the few clansmen with them, but dying in the process.

She told him that at that time she was a genin but the clan lineage made her physical and chakra prowess better than common chunin this being the Kumogakure where they are specialized in Taijutsu if that sounds weak.

She fleed from Kumogakure faking death in a mission to Kirigakure where she was sent to die because of past events, Making it look like she's blown up with her team who has been sent to make sure she died there, it only worked because they couldn't kill her in the travel, made in the sea between countries.

There she meet a Kirigakure chunin who thought she was a blood-related member of the Kaguya clan due to her appearance, and traits (hard bone horn, vitality, fierceness, and hair) got in love with her and sheltered her into his clan after one of the clan elders put she in a genjutsu and asked poorly questions about her past and family that coincided with her case because Kaguya clan is mad ASF...

She discovered she was pregnant soon after the body's dad died, now as strong as a jonin due to her clan and maturity, her senses thought something was wrong with Kirigakure due to the third Mizukage actions in the middle of the third ninja war and escaped the now decaying clan after the somehow decimation of the seven swordsmen of the mist two of them being from the clan.

As running for her life, she also robbed a copy of the clan's secret arts scroll for her child.

While in the flee to Lightning land she was pursued by a few clansman water walking who finally started a battle with her at a point in the sea where they became exhausted in stamina and chakra as she planned beforehand.

but after killing most of them one destructed the sails and water and food supply of the boat she brought.

She had to paddle most of the way between the two countries without water or food while removing some water from the damaged boat.

It ended with her having to drink the clansman's bodies blood or die and the only motive she didn't eat their flesh was she could fish, she managed to do it in 4 days of sleepless paddling drinking blood, and eating raw fish and only survived because of the Kaku clan constitution digestive ability.

After reaching the land of lightning she traveled to the biggest city on the coast passing by as a robbed merchant's daughter with her transformation jutsu, the real one being rap*d by the bandits when Kama encountered them she was nearly dying them as payment for killing the bandits the daughter told some things to help her acquire the deceased merchant house.

While living after some months she started losing her might power and soon the body's previous owner was born, strangely breaking the tradition of the Kaku clan where every time they have twins(inserted lore for Kaguya birthing 2 sons) since many centuries ago, she thought it should be because "how weak" the father was and thought herself too becoming weak while pregnant.

The kid was born with two wide drop-shape horns and two small ones on the sides that are more like a crown on his head, as Kanmuri remembered, the only difference from the Otstsuki horns was his being black, also he had Hozuki's purple eyes.

She marveled thinking her son was sure to be stronger just based on that big thick horn and named him Kanmurikaku but learning from the mistakes of the past the mother changed it to Kanmuri Kaku.

A few years passed and before the body's 5 anniversary as if relieved of the body's owner learning how to control chakra, read, and train himself, his mother died from an unknown sickness, and after a discrete funeral, she arranged for herself the few properties from the merchant family left after the sickness treatment*(she sold some for the treatment) got appropriated by a random fat merchant with a familiar name acting like a mob with a bunch of thugs.

The original Kanmuri became a stray boy, but his strong body and chakra plus the ability to eat and digest things that shouldn't be eaten* (remembering you the fact Kin and Gin-Kaku turned into pseudo-Jinchuurikis after eating a hole into Kyuubi's stomach).

The only problem was when the merchant discovered that Kanmuri was a "ninja" and tried to kill the BPO, failed many times until he decided to put a mission on a small ninja village in Paradise isle's and the BPO had to flee to the nearby mounts and survived for a year, ending having to eat many poisonous and venomous plants and animals since he ate what could be eaten on the coastal "forest".

He was unaware of his weaknesses to dehydration from being a Hozuki clan member since isn't normal for the Hozuki plus Kaku physique until having diarrhea because he started "concocting" poison in his stomach after eating too many things that shouldn't be eaten and died or at least lost his soul from dehydration or diarrhea (since in Japanese folklore souls can be pulled out from both end holes, butt or mouth...)

Now a transmigrated or Reincarnated person got this "marvelous" child body and realized the kid was soo dumb that forgot he could change more than one disguise with the transformation jutsu, and only used it for hiding the Hozuki teeth and horn crown.

Thinking how parasitic dimensional alien bloodlines affect the human brain, and why only Uchiha, Senju, Uzumaki, Hyuga, and Moon Otsutsuki are clearly affected by it in the series Kanmuri sighed.

Accepting this new name, Kanmuri crawled out of the rain into the cave/burrow the BPO was living in and started to refine the chakra since it's said it boosts the body's recovery speed.

Marveled by how familiar but strange the alien energy is, he lost the track of time and only remembered when realized how damp, filthy, hollowed his stomach, and thirsty his new body was.

Slowly walking to a puddle of water in a rock that remained after the rainstorm, seeing his reflection, a famine-looking boy looking be in his early teenies but with a baby face, even if he was below six years old, the most uncommon features being Crown-like horn and shark-like teeth, hair being a mixture of pale sand and silver white, skin being more colored than other Hozuki he saw in the anime but the Kaku lineage and solar exposure probably played a role in it.

Then he threw his head below the shallow water and drank it entirely.

Felling like it was a cold gasified cola drink after days without water he thought that was good to be alive.

Then he burpled some poisonous gas smelling like burnt rubber and chemicals with a pint of poisoned rotting insects. The burp made him aware of the burning sensation in his stomach and throat.

After drinking the water until puking some toxic waste five times and washing himself and his clothes, he slept for a day.

The next day he was feeling better but hungry, then he prepared to collect food before he start to train to recover and strengthen his new body and power.

This time going to nearby trees and collecting their sap, inner bark, a few seeds, and luckily a bird and some eggs, this while training tree walking, failing a few times before catching his feet.

After making fire with kunai and flint, he cook the bird, seed, and eggs that he ate while drinking some sap. After the meal, Kanmuri felt his body digesting it ridiculously fast and producing physical energy.

As if he's a sponge in the water, he even felt as if the mass was been transformed into energy as he drank a bottle of sap plus the water and don't feel any heavier on his stomach even feeling lighter as if he was using heavyweight equipment in a military training course and suddenly dropped it while running.

"This stomach can only be surpassed by the strongest beings in DBZ world..." He said with irony touching the abdomen that looked skinnier than ever would be in his past life.

After training a bit with the few kunai shurikens and ninjato that he had, he got 5-7 precision with the shuriken at 5 meters but already knew how to throw kunai and use a one-handed straight blade due to post-adulthood chunnibyou syndrome. Because of that, he had an easy time hitting all times at twice the distance with kunai and using a ninjato in this new body.

Relearning the transformation jutsu was easier with his new chakra control and he made his way to the Port city, to recover the Hozuki clan scrolls and to gather the information and knowledge he need for his future plans.
