Edelweiss

"I am the demise who comes from the distant summit, the one who splits earth and sky with two blades. My name is Twin-Wings Edelweiss. Childish lad, you will learn how wide this world is."

- Edelweiss

Edelweiss is renown as the Twin-Wings and the World's Strongest Swordsman. She is considered to be the most wanted criminal, but whose capture was abandoned due to her monstrous strength.

Appearance


Edelweiss is a beautiful young woman with a voluptuous figure, long pure white hair that extends to her back with bangs that cover her forehead; the left side of her bangs slants to the right, while the right side of her bangs slants slightly to the left, she also has beautiful clear crystal-blue eyes.

Whenever in battle, she is usually dressed in a white combat dress akin to a bikini with a breastplate, a garter belt on her waist with features on its side, a crown-like bonnet, which has white feathers on both sides, armored shoulder pads that have a short white cape, and a silver necklace around her neck that is sort of shaped like a ribbon in the middle.

Outside of combat, Edelweiss' first casual clothes has shown to be dressed in a white top that slants on her right shoulder revealing her black bra strap, a pair of jeans, and two bracelets on her left wrist.

Personality
Edelweiss has shown to be a calm, cool and collected woman as well as a swordsman. Despite being known as the worst criminal, she is honorable, respectful as well as gentle, as shown when she attempted to give both Ikki and Shizuku Kurogane a chance to leave if the two chose not to fight, partly because the two were children. Though it is shown that she held no interest in the plot of Akatsuki Academy, but owed a debt to their leader. In spite of Ikki still choosing to fight against her, she still tried to give him a chance to leave if he was to turn around and walked away but also knows that a person must take responsibility for the choices they've made, as she wouldn't let the two siblings save Nagi Arisuin stating that it was his choice to enter the underworld's society as a criminal.

Though she had taken an interest in Ikki out of respect and admiration for his strong, noble will to protect others and fought him as a swordsman and knight, instead of as a child, this increased even more after he was able to use his Blade Steal to replicate her technique as well as being able to wound her. Before Edelweiss' departure, she told Kurono Shinguuji who she respectfully called World Clock to inform Ikki that she hopes that he'll become a worthy opponent for her the next time they meet.

Edelweiss suffers for not having a reason to fight, despite all of her power. After she protected her country during the Baltic Crisis, she became isolated, not knowing what she should do. She thus is still searching for a reason to wield her sword, in other words, her chivalry, she even admitted made her jealous of Ikki and Stella who already have their reasons for holding a sword. Edelweiss also enjoys making sweets.

History
Edelweiss lived a normal life as a child with her parents and loved to make sweets becoming rather overweight in the process. Her parents soon left her under the care of Ryouma Kurogane who had lived nearby where she could get some exercise but had proven to have a remarkable talent in swordsmanship.

Fifteen years ago, when Estonia was about to become the stage of a war between both the League and the Union, a teenage Edelweiss defeated all 300,000 soldiers of both sides becoming known as the Baltic Crisis as well as being what made her the world's most wanted criminal as well as the world's strongest swordsman. She later moved to the top of Edelberg mountain, located over 9,000 meters above sea level.

She was mentioned to have been a part of an event in the Middle East, during which she likely fought Naseem Al-Salem. At some point Edelweiss introduced Amane Shinomiya to Rebellion, seeing that he didn't want to live on the light side of the world. She also stopped the leader of Rebellion, "Tyrant" from killing Ouma, in their battle. It is possible that these actions or others are the reason she was left in Rebellion's debt and by extension Akatsuki. She was also informed of the dark future seen by Bakuga Tsukikage with his ability.

Akatsuki Strikes


Edelweiss first appears on top of the Akatsuki building and points her blade at Ikki. Ikki makes Shizuku leave him, recognizing the massive difference in their abilities (citing their encounter as premature by several years at least), and his resulting inability to protect her, barely managing to protect himself. Edelweiss gracefully comes down the building. She is able to easily beat Ikki in swordsmanship, power, and speed, even with Ikki activating Ittou Shura.

Edelweiss is eventually impressed by Ikki's strong will and decides to take him seriously and decides to kill him. She, however, fails to do so as he is able to stop her attack, by using Edelweiss' own swordsmanship against her, with Edelweiss later expressing her amazement at the degree to which Ikki was able to see through her technique. Ikki however, does lose consciousness, suffering grievous, but non-fatal wounds as a result of being unable to fully repel her attack, as well as having Intetsu broken.

Edelweiss is then met by an angered Kurono who was about to shoot her guns at Edelweiss but thought better of it. Edelweiss leaves Kurono with a message of wanting to fight Ikki again after he becomes a worthy opponent and then takes her to leave, expressing terror for Ikki's sake at the realization that he will likely face Amane Shinomiya at the Seven Stars Sword Art Festival.

Rising Spirit
Edelweiss later arrives at the Seven Stars Sword Art Festival, where she meets with Bakuga Tsukikage, who is accompanied by Rinna Kazamatsuri, Charlotte Cordé, and Sara Bloodlily. Edelweiss explains that she has come to see the final match between Ikki and Stella, noting that the battle is attracting a lot of attention around the world, as there are many other powerful Blazers present. Edelweiss is also interested in Ikki, believing that she will face him again in the future.

Edelweiss also watches the Finals of the Festival, between Ikki and Stella. She explains how Stella's faith is greater than Ikki's, and thus she is stronger than him. Edelweiss is then impressed when Ikki reaches an "awakening" and wins the match. After the battle, Edelweiss tells Tsukikage that Ikki and Stella have the possibility of preventing the dark future he has seen.

White Summit
Edelweiss later meets with Stella Vermillion, who has come to challenge her, along with Ikki, Ascarid and Yui Tatara, in preparation for the upcoming tournament between Vermillion and Cradleland. On top of Edelberg, where Edelweiss lives, Stella tries approaching Edelweiss, but she is unable to move and is even damaged, by Edelweiss' bloodlust alone. Edelweiss explains that this is the result of being a Desperado, and Stella can only face her by becoming a Desperado herself.

Stella then asks Edelweiss to train her, to which she agrees, on the condition that Stella guards her home for six days. Ascarid warns Stella that Edelweiss' Noble Art, Rule of Grace makes its target unable to break their promise or they die. Despite the warnings though, Stella decides to agree to Edelweiss' condition. Edelweiss also forces Ascarid and Yui to swear that they won't help Stella, while Ikki comes with Edelweiss.

Intense Cold Trial


After the confrontation with Stella, Edelweiss takes Ikki to her cabin, where she makes him all kinds of sweets. Ikki remarks how delicious her cooking is, with Edelweiss telling that she has enjoyed making sweets since her childhood. After Ikki asks, Edelweiss tells him about her past before becoming the world's strongest swordsman. Ikki then asks Edelweiss to train him in swordsmanship. Edelweiss though mentions that she can't teach Ikki much in swordsmanship, as the gap between their skills is far smaller than Ikki might think. She even mentions that Ikki has begun to make his copy of Edelweiss's swordsmanship his own technique. Edelweiss then says that she could teach Ikki in something he is sorely lacking.

Edelweiss takes Ikki to the peak of the mountain, where Edelweiss tells Ikki that his weakness is his immature and wasteful use of his magic. Edelweiss tells Ikki that if he can remain balanced on the pointed tip of the mountain's peak using just one finger, his magic abilities will increase greatly. Ikki decides to take the challenge, though he initially experiences great difficulty in the task.

The Assassin from Shinryuu Temple
Standing outside of her home, Edelweiss senses a powerful Desperado approaching. This Desperado is revealed to be Fu Xiaoli, one of the Four Sages of Shinryuu Temple. She then heads out, knowing that Stella is going to encounter Xiaoli. When Edelweiss finally does find Xiaoli, she is already fighting Stella. Edelweiss attempts to stop the fight, seeing that Stella is going to lose. However, Ikki then arrives, stopping Edelweiss from interrupting Stella's fight. Edelweiss briefly clashes with Ikki, with Ikki showing his new ability of mana defense and deflecting her attack. Stella eventually defeats Xiaoli and completed her task of protecting Edelweiss's home for six days. Edelweiss then says that Stella can now fight with her. Stella though refuses, wanting to return to Vermillion and Edelweiss respects Stella's decision.

Vermillion's Sword
After Stella and her group leave, Edelweiss is alone, thinking about the state of the world. She theorizes that after the issue with Or-Gaule is resolved, it won't be long before the terrifying vision seen by Bakuga Tsukikage will start to come true. She then leaves her home because she can't let a thing like that happen as it's the responsibility of those with power.

Abilities
Desperado: Edelweiss is a Desperado, a being that has broken the chains of fate. As such, she has far greater magic power than other normal Blazers being able to increase it through training. As a Desperado, she possesses the "attraction force" that enables her to force upon others the fate of what she desires to happen. Just releasing bloodlust alone, she is able to wound or kill others.

Contract Administration: Her ability as a Blazer is a causation manipulation, which is towards "contracts", letting her form binding contracts with other people. Edelweiss herself said that she could combat causation powers like Nameless Glory to a certain extent.



Master Swordsmanship: Edelweiss has both tremendous power and skill as a master swordsman, renown for being able to defeat three hundred thousand soldiers from the League and Union as a teenager, earning the moniker as the world's strongest swordsman. In fact, her swordsmanship surpasses even Ikki, a master swordsman stated to surpass that of Ryouma despite using his secret swords, negating two of them. Edelweiss still remained superior even after he learned her swordsmanship.
 * Twin Wings Style: Her unique swordsmanship, not meant for normal humans to the point of being godlike. It involves controlling and changing her nervous system to move her muscles in unison, granting instant acceleration, producing invisible slashes. Twin Wings Style converts energy into attack power and speed, close to one-hundred percent, leaving no vibrations, outclassing Ikki using Ittou Shura.
 * Vibration Strike: Edelweiss can sends vibrations into her opponent, similar to Ikki's sixth secret sword through their weapons or armor, being superior to his, causing blood to spurt out after both techniques clashed. She can use the ground beneath her opponents' feet to send these vibrations.
 * Vacuum Slashes: Edelweiss can leave scars behind a vacuum in the air through slashing the air, similar to Mark of the Wind.

Immense Strength: She has incredible strength, leaping from and to the top of Akatsuki Academy building without hurting her legs with little to no effort at all. Edelweiss overpowered Ikki in Ittou Shura, blocking his first and sixth secret sword.

Immense Speed: She has tremendous speed and reflexes, both of which has instantaneous acceleration, surpassing Ikki using Ittou Shura in their first match.

Body Supremacy: Edelweiss has flawless control over her whole body as well as its workings, being able to invent her own swordsmanship, which involves changing her body's nerve signals and move all of her muscles instantaneously. Ikki has acknowledged that Edelweiss' control over her whole body clearly surpassed his own control after he replicated her swordsmanship.

Mana Control: Edelweiss has superior mana control, superior to Ikki and as such Shizuku in precision, replicating Ittou Shura, where she focused mana inside herself instead of outside, maximizing the strengthening. She developed a personal and difficult training method on top of Edelberg, being able to instruct Ikki.

Device


Testament: Edelweiss' Device takes form as a pair of pure white wing-like swords.
 * Rule of Grace: Edelweiss' Noble Art, where a person makes a promise in front of her Testament and if the person were to break it, then their hearts will be torn apart. Though it doesn't have combat effectiveness, its binding power is unrivaled.
 * Scarred Order: This is a Noble Art, which lets Edelweiss issue strong commands to those opponents she injures.

Trivia

 * Edelweiss is likely named after a European flower, mainly found in the Alps. The word is derived from the words "edel" and "weiss" which means "noble" and "white" in German.
 * There is a theory that states that the Japanese swordsman who taught her was Ryouma Kurogane, which is possible since she saved his oldest great-grandson from the Leader of Rebellion, Adam Goetia. As well as giving his youngest great-grandchildren, Ikki and Shizuku Kurogane a chance to leave despite being in the dept of Rebellion and as such Akatsuki. Furthermore, she once quoted the same words that he gave Ikki when he was younger, which the latter recognize. It is officially proven in Volume 18
