Tashki is a mysterious woman of unknown origins, and has​ become more than a prodigy unlike any hero could ever imagine. Ventured against many evils throughout her endless generations of days of fighting, and is beyond different than most, she carries one of a kind unique wisdom and continues to learn more. As she is one of the few to enter the unknown boundaries known as the Eternity, it is an unknown boundary (Not reality or universe) connects all memories, dreams, other worlds, dimensions, realms, and other Gensokyos. As a guardian of Balance, and the Eternity, much like any other shrine maiden, Tashki reasons to fight is to do what's right for all and otherwise, never backing down to any matter that harnesses with Discord and/or Evil. Many even say in legends she's beyond powerful than any god/goddess or dragon due to her powers of Unknown Balance: Aflecs Astralus, and the Golden Aura: Nylos Infinitum.
 
Tashki is a master of Spiritual Swordsmanship, Ninjutsu, Aura Manipulation, Powerful Unknown Barriers, powers of the gods, and Magical/Arcana Artes. She is proclaimed with many titles of unknown legendary histories, yet appears to just be as any human in physical form. She and her friends respect other people's rights and titles under their plane and rule, for Equality and Neutrality.
 
As she is strong in many ways, she's experienced many things in many dimensions, time planes, universes across the Omniverse, and eventually came part with the Endless Cycles between Cosmos and Chaos, including the Realm of Kingdom Hearts. Despite of many histories she's made for herself, she intends to resolve all conflicts as fast and as much as she can, while allowing other heroes to fully fulfill their roles of their realms. And as she progresses and travels, she's learned to instead haste, but to be an Observer of everything before commencing any action.
 
Tashki is indomitably spirited, wise, kind, carefree, short tempered, and stubborn, but will do her best to help others when they're in danger or in need of help as a scent of her own nature as a Lunar Earth Angel. Her patience, calmness, and concentration, are mostly the key to her successes despite her anger and rage to thrive against the toughest of outcomes. She's also very gentle, delicate, often innocent, and romantic when with other beautiful women. Which could lead to possible weaknesses.
​
However as mentioned, she holds powerful anger inside that holds most of her negativity, proving the Dark Side Theory that foresights her dark side to exist in a different realm. But over time, that realm has dissipated enough to where her dark side is eventually going to become far of a greater threat than possibly anything to exist. In time, she is already bound with said darkness due to certain truths revealed to her after observing her own Gensokyo lost long ago. (Osana Reimu & ReiReimu)
 
Tashki's respects are usually formed in casual ways of speaking, treating everyone not high or low, but equal as her. And in comparisons from many dragons and gods, she's found as one of the most promising, powerful, and most dangerous legends to ever exist. There will be times to when she will often speak Old English when spoken to under various situations.

It is also been worded that after thorough observation toward a familiar realm with multiple possibilities and dimensions, she's chosen commitment toward creating a newfound project and force inspired from what she's learned, and has spoken, "One day, my Earth's Future shall be bleak. But when the time comes, so shall a new hope rise for our dark distant future. So I shall say only this: Glory...to Mankind."

And so, the Order of the Ethereal Light (NeW YoRHa) was born...somewhere within the Great Abyss, and out of it.
