Arisu's Entity [WIP]

Description: The God Tree. When a seedling is successfully planted, it begins to drain the natural  energy of a planet, condensing it into chakra fruit that can then be consumed for massive power. When an Otsutsuki is sacrificed to the seedling, it creates a Juubi, the 10 Tails.

Earth's God Tree cultivated part of the world's chakra, and eventually produced a chakra fruit that was consumed by Kaguya Otsutsuki. Viewing all chakra as hers, Kaguya later merged with the God Tree in order to help her take the chakra from her children, creating the 10 Tails out of herself in the process.

Even though the 10 Tails was defeated and was later split into the 9 Tailed Beasts, its husk and Kaguya's residual chakra remained. In this form, it was known as the Gedo Mazo, but as the husk of the 10 Tailed Beast, it was still a drained and Otsutsuki merged God Tree.

Arisu linked to the Gedo Mazo when she unlocked her rinnegan, thus allowing her to summon it at will. Over the course of several battles and much training, and due to the life force draw that is used to sustain the Gedo Mazo, Arisu's life force has become more and more entwined with it. As an Otsutsuki with massive reserves of chakra, above even Bijuu, Arisu's own reserves were enough to stimulate the reserves of Kaguya that were sealed into the God Tree.

As she was 'awakened', she began to gather more and more chakra, spending her time growing and gathering natural chakra using the Gedo once again. During that process, a single Chakra fruit was produced, containing a mixture of the Natural Chakra of the planet and Kaguya's chakra herself.

Upon consuming the fruit, Arisu's abilities were amplified as she was given a rush of chakra, unlocking several new abilities akin to the more powerful of the Otsutsuki.



Flight: Most Otsutsuki gain the ability to fly after consuming a chakra fruit. After spending 500 experience, they can fly at will using their speed for the flight speed, with their ability to turn and make fine movements controlled by their coordination.

Progenitor of Chakra: The God Tree's abilities were responsible for making the Senju clan from the humans who discovered it. Kaguya Otsutsuki was the person that the Kaguya clan directly descended from. With both the God Tree and Kaguya's essence linked within her, Arisu was granted greater access to both the Senju and Kaguya clans. She gets the benefits of one clan without an implantation, and can implant the other one without any negative modifiers if she gets the opportunity to. However, she cannot implant anything other than those two Kekkai Genkai. Regardless of which is chosen, they both require full investment from scratch.

Noble Blood: Otsutsuki are known for their evolutionary capabilities. There are different levels of power to them, and each level grants additional evolutionary perks. There is only so much that an Otsutsuki can advance on their own though, and they often gain additional power through devouring Chakra Fruit, or draining the chakra from others. As they evolve their blood and power, they begin to undergo physical changes. While the costs of each level stack, the bonuses replace each other.

• Noble: This is the lowest form of evolution. At this level, the Otsutsuki is granted a horn, their eyes shift from a silver or blue color to a gold color. Arisu had already achieved this level, although she hadn't gained access to the evolutionary power until consuming the fruit. This level is always active and costs nothing. The Otsutsuki receives a boost in their physical abilities, gaining a Unique Boost of a + in Strength, Constitution, Speed, and Coordination, as well as an increased chakra pool of 50.
  
  
• High-Noble: The next form of evolution in the process. The horn becomes tipped in a darker tinged color. This level costs 500 exp and replaces 'Noble' boosts as it becomes permanent. The Otsutsuki's physical skills are further enhanced, as their Strength, Constitution, Speed, and Coordination all receive a ++ UQ boost, and their chakra pool is increased by 150.
  
  
• Royal: In this level of the evolutionary process, the Rinnegan of the user undergo a change as well, shifting from their normal purple into one of several different colors. This level costs 1000 exp and replaces 'High-Noble' as it becomes the new permanent mode. The Otsutsuki's base power is now raised to its highest degree as their Strength, Constitution, Speed, and Coordination are enhanced by a full tier of UQ boosts, with their chakra pool increasing  by 300.
  
  
• Sovereign: This is the final stage of an Otsutsuki's evolutionary process. A pattern forms on their skin and like the horn, becomes tinged in a darker color. Unlike the previous forms, this one isn't technically permanent, and can only be accessed by a 'Royal' level Otsutsuki who has completed the control level. This level costs an additional 1000 experience to unlock. This mode is only temporary, but it doubles the previous boosts to 2 tiers each, and a chakra pool increase of 600 for the duration. With the Control level unlocked, the user can access this mode for up to 5 posts for 50 exp a post. After a Bond level unlock, the user can access this mode for as many posts as they pay for, unlocking an extra post for 100 exp a post after the first 5 at their reduced cost..
  

Third Eye: After investing 500 experience, a third eye opens up on the Otsutsuki's forehead, forming a primarily red Rinnegan. This eye is always active when opened, granting a bonus to perception of 1 UQ tier, stacking with the normal Rinnegan's Chakra Visualization. Whenever the eye is open, it costs 0.5 chakra to maintain.

Drawing power from the essence of a celestial body and the remainder of another's chakra can lead one to being subjected to possession by those beings. Kaguya Otsutsuki was a domineering presence in life, and her chakra seeks to wear down the mind of the person who contains her, to free itself and restore herself back to life once more in a new vessel. In order to fully command her power without wearing down the user's soul, they need to fight for dominance and subjugate Kaguya's power to their own will.
