Edelweiss

Edelweiss is the strongest swordsman Blazer in the world, striking fear into the hearts of even the world's third and fourth ranked Blazers. She is considered to be the worst criminal, whose capture is abandoned due to her monstrous strength.

Appearance
Edelweisse is a very beautiful voluptuous woman. She has a cold ice like stare in her crystal clear blue eyes. She has ice cold, snowy white hair, that is long enough to reach down all the way to the back of her shoulders. Her white hair is also long enough in the front to reach and covers her entire forehead, with her middle bang slanting down to the right, but then shifting slightly to the left as it goes down.

Edelweisse, is shown to wear a dress akin to a one piece swimsuit with breast plates and a garter belt on her waist with feathers on its side. She also wears a beautiful white crown-like bonnet that has beautiful white feathers coming out of the left and right ends of them. She also wears white shoulder pads, which holds in place a snowy white short cape, that waves in the breeze. Edelweiss also wears a silver necklace around her neck that is sort of shaped like a ribbon in the middle.

Personality
Edelweiss is a calm, cool and collected woman. Despite being a criminal, Edelweiss is very honorable, respectful and gentle. This is all shown during her first appearance when she offered to let Ikki and Shizuku Kurogane live if they chose to not to fight, partly because they were children and because she was in debt to Akatsuki, thus was not there willingly and held no particular interest in Akatsuki's plots.

She has taken an interest in Ikki Kurogane after their first fight. This is out of respect and admiration for his strong, noble will to protect others and his ability to leave a wound on her despite his young age, even more so for being able to see through and replicate her techniques in under a minute. Before leaving, she told Kurono Shinguuji (calling her "World Clock") to tell Ikki to become a worthy opponent for next time they meet.

History
Little has been revealed about her history so far, though at some point she became indebted to Rebellion, and by extension to Akatsuki Academy. She also stopped the leader of Rebellion, Tyrant from killing Ouma Kurogane, during their battle.

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 leave, expressing terror for Ikki's sake at the realization that he will likely face Amane Shinomiya at the Seven Stars Sword Art Festival.

The Finals of the Seven Stars Sword Art Festival
Edelweiss is later present at 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.

Abilities
Desperado: Edelweiss is a Desperado, a being that has broken the chains of faith. As a Desperado she has far greater magic power than other normal Blazers. As the strongest Blazer in the world she possibly has even greater magic power than other Desperados.

Master Swordsmanship: Edelweiss is extremely skilled in dual wielding swordsmanship. In fact, her swordsmanship skills greatly surpasses even that of Ikki Kurogane who is a master swordsman himself, capable of swinging her swords to the point where they are impossible to be seen by the eyes even for Ikki. Her swordsmanship's signature is it's immense speed. Four of Ikki's Seven Secret Swords Techniques used in their fight couldn't even harm her (though she momentarily fell for Shinkirou).
 * Vacuum Slashes: Edelweiss is capable of using a technique similar to Ayase's Noble Art Mark of the Wind. When Edelweiss slashes, she can leave behind a vacuum in the air, which can cut the opponent.

Immense Strength: Edelweiss possesses vast amount of physical strength. All of her attacks were able to easily overpower Ikkis' attacks while he was using Ittou Shura, easily blocking Ikki's Sixth Secret Sword, and in the same manner intended by Ikki's own technique, caused massive injuries to both of his arms. Her leg strength is great enough for her to casually jump down from the top of the Akatsuki Academy safety and back up in a single leap for both.

Immense Speed: Edelweiss possesses amazing levels of speed. She was easily able to keep up, with Ikki, who was using Ittou Shura, and even surpassed him in speed.

Immense Reflexes: Edelweiss can move at incredible speed. Even to Ikki while using Ittou Shura, her attacks were too fast for him to even see them, though he was able to eventually learn her technique by focusing on her muscle movements.

Immense Presence: Because of Edelweiss immense power and skills, her sword spirit alone can intimidate even the strongest Mage-Knights without even being in seeing distance. Even Kurono Shinguuji and Nene Saikyo, two of the strongest Mage-Knights in the world, stopped in their tracks the moment they felt her sword spirit.

Device
Unnamed Sword Device: Edelweiss's Device which takes the form of a pair of wing-like swords.
