Valkyrie

Valkyrie (ヴァルキュレ) is the Goddess of Destruction (破壞の女神) who taught Seiya Ryuuguuin the skill Valhalla Gate, an ultimate skill of definite destruction.

Appearance
Valkyrie is a tall and muscular woman with short white hair with a few red tips on the right side. She has red eyes and appears almost nude with chains only barely covering her body.

Personality
Valkyrie has a rough, tomboy, in-your-face, out-in-the-open mindset, from her inner opinions to her outer appearance. She is fearless, has shown some masochistic tendencies and seems to enjoy bullying other goddesses - especially in a vulgar manner (she enjoys fondling with Rista's and Ariadoa's breasts). In addition she's quite hot tempered, flying into a rage after Seiya Ryuuguuin calls her an 'exhibitionist'.

She likes painting, though she is not very good at it. She immediately executed Crossed Thanatos for destroying her painting, saying that "no matter who destroyed her painting, whoever it was they would die".

Valkyrie also enjoys fighting, as she smiles, realizing Crossed Thanatos has the strength to fight back. After realizing there was no conventional way to defeat the demon she uses her ultimate move; Valhalla Gate.

When Seiya requests Valkyrie to train him, she was initially reluctant to fulfil the demand, while also refusing to teach Seiya the Valhalla Gate; however, Valkyrie apparently had a change in heart upon realizing Seiya's commitment and potential sacrifices, teaching him Valhalla Gate, even going so far as to call him a "fine man."

Gaeabran Arc
Valkyrie is bumped into by Ristarte which she took offense to. The younger goddess quickly gave her apologies to the Goddess of Destruction. Valkyrie deciding to have some fun then began to grope her junior's chest until the other breaks into tears. Satisfied that her perversion was sated, she warned Ristarte not to bump into her again. She almost gets into a fight with Seiya, who tries to goad her into sparing with him. Angry at the last of respect from the upstart hero, the goddess attempt to attack him but was stopped by Ariadoa. The Goddess of Seals manages to calm the two down, though the other goddess relented after being promised to fondle Ariadoa's chest next time.

Later Valkyrie was seen at the top of the temple roof in the Divine Realm, busy with her art piece, when Seiya lured the Crossed Thanatos to the area. He purposely allowed it to attack him, only to dodge at the last moment, so that the summons attack would destroy her piece. Enraged the Goddess of Destruction turned her fury on the intruder. Though Crossed Thanatos proved to be a difficult foe, she managed to kill it using her Valhalla Gate at the cost of being exsanguinated. After recovering, Seiya now sees her true power in casting Valhalla's Gate, believes that she is the one to train and asks her to teach him the move. Though she tried to tell Seiya the risks of such a move, he was insistent to learn it. Seeing his determination, she relented and agreed to train him.

Rista then witnesses the two in bed naked, and misunderstood that Valkyrie was having sexual relations with Seiya a act against divine law with a human. However in reality Valkyrie was transferring her spirit energy to Seiya in order to help him perform Valhalla Gate.

Seiya Ryuuguuin
Initially, Valkyrie was hostile toward Seiya, due to him calling her an exhibitionist. She would have killed him, if not for Ariadoa's interference. Once Seiya sees her Destruction techniques, he asks her to train him, due to him not being strong enough or properly equipped to take on the Demon Lord. She deemed him worthy after noticing his willingness to sacrifice himself for the greater good, and so became on good terms with him. She also taught him her techniques, such as Valhalla's Gate.

Ristarte
Valkyrie loves to bully Ristarte, due to her status as a new goddess, often mocking her lack of experience and calling her third-rate. She'd also physically bully her by fondling her breasts, calling them the only attractive thing about her. When Ristarte walked in on the Valhalla's Gate transference ritual, she got jealous of Seiya, going so far as to make a doll out of her hair for him. Irked by this, Valkyrie considered toning down her bullying, out of concern for Ristarte's mental health. She left Ristarte alone after Seiya's death.

Ariadoa
Valkyrie usually shows deference toward Ariadoa, due to her high rank, as seen when she listened to Aria when she told her not to harm Seiya, due to his important role. Valkyrie isn't nice to her, but usually respects her opinion. This does not spare Ariadoa from Valkyrie's usual habits, as she's especially attracted to Aria, due to her huge breasts. Aria is usually cautious about Valkyrie's fondling habit, but relents when necessary, like she did when she saved Seiya's life.

Powers and Abilities
As a goddess, Valkyrie is immortal and cannot be killed by conventional means. Valkyrie is among the one of the strongest gods, with the power to kill absolutely anyone with her ability Valhalla Gate. Because she is immortal the actual cost of Valhalla Gate will severely damage and hurt her, but not kill her. Due to this she can seemingly kill anyone at all times. Besides that, she also has an arsenal of other powerful skills and abilities who has only fought Crossed Thanatos, but due to the monster's almost complete invincibility, it cannot be estimated just how powerful her other skills and abilities are. Given her physical appearance she is likely physically strong as well.

Trivia
