Death Seeker: She's fighting because SOMEONE HAS TO, not because she actually wants to. It makes it very difficult for Sword and Ouka to deal with her.
Earn Your Happy Ending: While she couldn't save the planet she managed to at least save some of the inhabitants on it via the the Black Death Tree which resurrected many of those killed on her quest and the group seek out a new planet free from the tyranny of gods. What's more she and Zero are reborn in the next life (albeit gender swapped) and meet each other once again.
Handicapped Badass: While her arm DID grow back after the battle, losing it didn't slow her down in the least.
Helpless Good Side: Subverted. Despite all that she does, her love of humanity is so great the gods themselves think it's godlike and make it the goddess of mercy. So while Shirohime may be Kurohime's love and kindness personified, when they are split, she's the one left with the powers.
Powered by a Forsaken Child: The Black God Tree ever present on her. It feeds on the rage of the people she's killed. Implied to be the reason why she can't willingly stop fighting; if she does, it means they all died for nothing.
Back from the Dead: Twice. The first time is involuntary, as it's a side effect of Asura's time reversal scheme. The second time occurs after she commits suicide in Zero's arms; however, she's effectively a Black God Tree skeleton.
Earn Your Happy Ending: Yamatohime's power purifies the Black God Tree and those absorbed within it, Kurohime is able to resurrect those people, Zero and the rest of her True Companions live and the human race lives to see a few more billion years. This comes at the expense of the planet, Yamatohime... and Yashahime. Win some, lose the rest.
Healing Hands: The most common bullet she uses is the Healing Bullet.
Laser-Guided Amnesia: In the first arc, as a result of losing her ability to love, she can't recall just why she hates the gods. Later on, her memories act as a self-inflicted curse, since the pain of losing Zero keeps her from using her full potential. If she loses her final memory of Zero, she will become Kurohime for good.
Pure Is Not Good: Himeko cites this as the reason Zero wants to end the world. He is a problem solver and an innocent, seeing the world in black and white. By his logic, if humans cause the world's strife and the world is going down in flames in some thousand years anyway, why not just cut out the middleman and put the world out of its misery now?
Because Destiny Says So: Her fate is to complete Yamato Senryuuto. She's NOT pleased with this plan at first, but thanks to The Power of Friendship and her mother's apology, she comes to realize that she was the only one that was devaluing her life.
Defrosting Ice Queen: Her opinion of humans raises over the course of the series, to the point she is willing to risk her life saving one. It did drop again for a short time, but she was able to reconcile her views once she got a hold of herself again.
Heroic Sacrifice: She convinces the Spirit Kings to send her consciousness back in time and takes the bullet that Himeko refused to shoot at her, completing the Ultimate Blade.
Half-Human Hybrid: According to the elder of Asura's village, Asura is actually a human "blessed" with the power of Yamatohime. This is why she can serve as Yamatohime's sacrifice for the Yamato Senryuuto.
Unstoppable Rage: After Taking the Bullet for an innocent little girl named Sara, continuous fighting for the sake of the people who are inadvertently weakening the Spirit Kings with their actions drives Asura to abandon her humanity and attack everyone and everything in sight. She is also harboring intense resentment about being forced to serve as Yamatohime's substitute within the Ultimate Sword.
The former leader of the Onimaru Brigade and Kurohime's former Dragon. Was betrayed by her and branded with the kanji for "dog." Has sworn vengence on her but funnily enough is still attracted to her. Sword attempted to turn him into a snake minion, but his willpower enabled him to resist the change, causing him to turn into Tsucchi, a small, mute, lizard-like...thing.
Sleep Mode Size: Their bodies are mostly hard-impacted snow, so after Kurohime melted them using Asura, they take the form of small children. They can Fusion Dance to take on a teenaged form of whoever's in control.
The Grim Reaper and High God. Colossal asshole. Zero takes his place after his death.
Kick Them While They Are Down: Uses the souls of the dead and the living as shields, mocks Kurohime and Zero, impales her and tells his most loyal follower to her face that her love for him means absolutely nothing to him, after impaling her as well.
The last one could count as his Moral Event Horizon since until then it was understood that gods cared about each other.
Heel-Face Turn: Effectively. It takes her longer, and she is not quite as willing to let it go, but ultimately she quits holding her grudge in such high priority since Kurohime living will help solve the more IMMEDIATEproblems at the moment.
Never My Fault: Though Kurohime did interfere with her work, there are certain things (specifically, the death of her teammates) that Kurohime was absolutely not responsible for that she holds a grudge over anyway.
Complexity Addiction: It's pointed out over and over that Yashahime could kill almost anyone who's appeared in the manga so far. Yet when faced with the prospect of doing just that to Kurohime, she has to devise some sort of scheme and draw it out, which ends with Kurohime either escaping or getting stronger.
Amusingly enough, the one time she decides to just kill Kurohime would have ended with her OWN death, if it wasn't for the fact that she justdoesn't die.
The Dreaded/The Friend Nobody Likes: With the exception of Igudo (who might not HAVE emotions), the other gods and supernatural creatures react with fear when and wherever she shows up. The surviving gods quickly write off her death and move on to another galaxy rather than avenge her.
Evil Counterpart: To Kurohime and Sword. Like them, she is an incredibly powerful woman empowered by her emotions. While the former is motivated by love of humanity and later Zero, and the latter is motivated by love of Darkray, Yashahime's real motivations are madness and love of killing.
Hoist By Her Own Petard: She captures Yamatohime in her weakened state and links her powers with her own. Since Yamatohime is linked to the planet. Yashahime becomes the planet itself making her all powerful. When Kurohime gains the planet slaying sword, she claims that it'll kill Yamatohime in the process...only for Yamatohime to offer up her life to help power the sword. Eliminating that stop gate and giving Kurohime the all clear to finish off Yashahime for good.
Stabbed herself to keep her from killing Kurohime and then claiming the resulting scar is Kurohime's fault.
Claimed that the God of Death isn't supposed to be concerned about anything or anyone, then blushing because he asked if her wounds had healed.
Implacable Woman: for the sake of her vengeance and spite, she will endure literally anything without stopping; she's very, very bad at staying down for more than a few moments at any given time.
It's All About Me: Initially, she comes into the plot because Ghandara was killed. But eventually, her revenge against Kurohime becomes more about satisfying her own desire to kill Kurohime for killing Darkray. Even with The End of the World as We Know It going on, her main motivation is "get enough power to kill Kurohime for killing Darkray."
Wrong Genre Savvy: Believes herself to be a Broken Bird trying to avenge her beloved's death. No, Yasha, the woman you're thinking of is Sword.
Also, she assumed that Dark Zero MUST want to be a High God and rule the heavens with her. After all, why else would he just destroy the world? Because he hates the world and really DOES want nothing more than to watch it burn.
Yamato Nadeshiko: She looks the part with the kimono and katana and sometimes even acts the part with a polite and calm demeanor, but she's actually a cruel and jealous bitch.
Yandere/Cute and Psycho: Not necessarily a most triumphant example, but very much textbook; she would have murdered Sword just because Sword was standing next to Darkray when he turned down Yashahime's offer to spend time together.
Heel-Face Turn: In a similar vein to Sword. As Ouka sees it though, nothing they could do to Kurohime could be worse than what she's doing to herself, which generally takes the wind out of revenge's sails.
Zero and Rei's foster father, after their mother died. The greedy leader of the Wolf Brigade.
The Atoner: After he is killed, he becomes Kandata, the ferryman of the Styx, to try and figure out why Rei spared him. In the process, he makes up for his misdeeds by helping out Himeko and the others, not only at the river Styx but also by turning back time to let Himeko get a second shot at saving Rei.
Big Damn Heroes: Made an ark out of his and Kairyu's bones to help save the last living humans.
My God, What Have I Done?: After death, it finally hits him how horrible a person he was, especially when Rei admits to him (as Kandata) that as horrible as Doc was, there was still something likable in him.
The Power of Love: Himeko cites this as the reason why Rei spared him. Even as horrible as he was, he was still counted as a father figure to Rei, if only because Rei and Zero never KNEW their REAL father. Yup, Doc won simply by default.
Too Dumb to Live: It's easy to count on one hand the things in the Past arc that aren't his fault.
A member of the Wolf Brigade alongside Doc, Rei and Zero.
