Ikki Kurogane

"Here, with my greatest weakness, I'll defeat your greatest strength!"

- Ikki Kurogane's catchphrase

Ikki Kurogane is the main male protagonist of Rakudai Kishi no Eiyuutan. Despite him hailing from a well-respected clan that has produced superior Blazers for generations, Ikki is considered to be a failure even for an F-Rank Blazer and known as the Worst One. He studies in Hagun Academy as a repeat student, as a result of the previous staff ensuring that he couldn't attend classes.

After Kurono Shinguuji took the position as the Director and fired all the other staff involved in it, Ikki was promised that if he were to win the 62nd Seven Stars Sword Art Festival, then she would allow him to graduate. In the finals, Ikki became one of the three Desperados of Japan and became the current Seven Stars Sword King. He also is participated in the tournament between Vermillion and Cradleland as a part of Team Vermillion.

Appearance
"There was beauty and kindness in your face, yet one could also clearly see strength within that straight-backed, clean-cut figure… and to add on to that, a robust musculature, honed and trained to unblemished perfection, it's just wonderful. You are, without a doubt, my ideal man."

- Sara Bloodlily's explanation of Ikki Ikki is a young man of average height with spiky black hair and gray eyes. He is described as having a lean but well-built toned physique and cute face, which makes him popular with both younger girls and even older ladies. Both his physical features and gentle looks is one of the reasons why Sara wanted him to be her nude model. Ikki also bears a strong resemblance to both his father and older brother.

There have been situations where Ikki has worn several clothes in the series based on the time or event, he is mostly seen dressed in the standard uniform for Hagun Academy.

After dying at the hands of Or-Gaule and being revived by Shizuku using Aoiro Sekai, Ikki returned to the appearance of a ten-year-old and as such has the physical and features abilities of a child.

Personality
Despite his harsh childhood, Ikki has shown to be a strong-willed and noble young man with a caring personality, which has been shown throughout the series as he when he helped others like his classmates improve on all of their abilities with their devices despite everyone prior treating him like a failure. This holds true for those struggling to become better on their own, as he understands what a hard road it was. Though Nagi has stated that this is can also a bad thing since Ikki was too used to being hurt that he wouldn't be able to hear the screams of his own heart, a fact proven before his fight against Kirihara after he had a panic attack and during when Ikki couldn't see through the situation first.

Ikki is shown to be quite calm in even the most arduous of the situation, as seen when he stayed calm the entire encounter with Kuraudo even brushing off the fact that he was hit with a bottle, trying to avoid the fight even after he was spat on. He can also be cold in battle and doesn't mind enjoying a heated battle with a strong opponent, which is shown several times in the Selection Matches and Seven Stars Sword Art Festival.

When it comes to dealing with women of his age and the whole academy in general Ikki is clumsy because Ikki has no prior experience with them outside of respect towards a superior or as a knight. This is shown when he confronts Stella on that subject. Due to his years of being discriminated against for being an F-Rank, Ikki is not entirely used to his sudden rise in popularity and often doesn't know how to best deal with his many female fans.

Despite situations implying otherwise, he is not very perverted. He usually tries his hardest to show restraint and respect to the woman who acts lecherously around him, such as Stella and Shizuku. He also chose not to have sex with Stella at the log cabin they were staying, even though she suggested it, knowing he needed her family's approval first.

Abilities
Desperado: During the finals of the Seven Stars Sword Art Festival against Stella, Ikki reached his "Brute Soul" and became a desperado, a being whose broken the chains of fate that binds them. Like others, he can increase his magic power based on his training, a feat that no normal Blazer can do. Ikki can also influence fate and exert an aura that is able to intimidate others using his presence. During his fight with Iris, he was able to influence the causation of "Killing" and could cut through her Orichalcos using his final secret sword.

Doubling Physical Power: Ikki's ability as a Blazer. He is able to double his physical abilities, but this has been considered useless as others can enhance their physical abilities 5 to 6 times using natural magic thus making it the worst among all Blazer abilities. Ikki was able to use his superhuman body control and willpower, in order to ignore his survival instincts, which resulted in his Ittou Shura and later Ittou Rasetsu.

Immense Strength: Having undergone a rigorous training regimen to make up for his low magic, Ikki attained an exceptional physical condition that granted him an A in Physical Attributes. Most of the time, he applies this to his sword letting him counter most attacks from other stronger Blazers. Since Ikki is able to ignore his bodies survival instincts, he can draw out incredible strength able to defeat Sirius Vermillion in arm-wrestling without visible effort.

Immense Speed: Ikki possesses remarkable speed due to his retinue of running twenty kilometers a day, letting him avoid high-speed attacks from Blazers without wasted movements. After stealing Edelweiss' Swordsmanship, he became able to move so fast that most people can't even see him albeit hear him move.

Immense Reflexes: Alongside his speed, Ikki also has outstanding reflexes, which he honed to near-perfection making them sharper than others. He has shown several times to be able to react to, dodge and even counter a number of fast Noble ARts, bullets, etc. Having stolen Edelweiss' Swordsmanship, his reflexes were heightened to where he could use Raikou without Ittou Shura.

Immense Stamina: As a result of his continuous physical training, Ikki has incredible amounts of stamina above that of most people even Stella. Despite being injured, he has still shown to be capable of fighting in an effective manner. He endured Yuuri's noble art, which both selection candidates and trained guards to fall to the ground in an instant. Both his stamina and endurance are most highlighted after being poisoned for weeks, but still made it to his match with Touka and use Ittou Rasetsu.

Master Swordsmanship: Ikki is an incredible master swordsman whose skills are self-taught due to continuous training by observing other swordmasters, challenging dojos, studying in libraries and museums. His sword skills were enough to fight against powerful Blazers who should outclass him. Ikki received praise from the God of War and Twin Wings, surpassing even the Samurai Ryouma, as well as being a potential rival for Edelweiss. He even fought on par with the 4th Rank Blazer, Iris Ascarid and defeated her earning the nickname Sword God.


 * Seven Secret Swords: Ikki's seven original sword techniques


 * Ten'i Muhou (天衣無縫, Heaven-Clad Null Shroud): Ikki learned the ultimate move of the Ayatsuji Itto-ryu, in which the user counters the opponent's attack with minimal movement. Ikki used an imperfect version of this move on Kuraudo.


 * Mutou Dori (無刀取り, Weaponless Catch): Ikki can use one of the techniques of the Yagyū Shinkage-ryū, which uses the power of his fingers and wrist movement to catch the opponents weapon and snatch it away. Though Ikki used this alongside Ittou Shura, making it unclear how well he can utilize Mutou Dori without it.


 * Edelweiss' Swordsmanship: After his initial encounter with Edelweiss through Blade Steal and utilized it at the last moments to wound her before passing out. After being able to recall it again, it boosted his speed to where Yuudai Moroboshi, the former Seven Star Sword King couldn't react to his speed despite hearing him and he has evolved to where he could use his Seven Secret Swords without Ittou Shura. Edelweiss herself even stated that he started to make her swordsmanship into his own adapting it to better fit him.


 * Tsunoou/Harmonic Bullet: A unison attack between Ikki and Stella, in which he jumps forward and attacks using Saigeki, then Stella sends him forward using a powerful swing sending him forward with much greater strength than normal. It was named Tsunoou by Ikki and Harmonic Bullet by Stella.


 * Amatsu Raikou (天津雷光, Heavenly Lightning): A technique, in which Ikki delivers a continuous barrage of 180 slashes, where the 90th to 108th slashes is delivered in roughly one beat like a lightning strike. Amatsu Raikou is an evolved form of Amatsukaze combined with Raikou.

Master Hand-to-hand combat: Ikki is very adept in various styles of martial arts in order to make up for his lack of magic power. He was able to deal with five Blazers wielding their Devices without using his own while holding black enough to injure them. Ikki has also shown to be skilled in Ukemi, a martial art, which focuses on receiving blows and strikes, then dispersing the force through his body, and surviving deadly blows.


 * Trackless Step (抜き足, Nukiashi): Ikki can utilize the ancient martial art technique, which combines breath control and footwork, letting him seep into the unconsciousness of his opponent thus making them difficult to perceive until it's too late for them to avoid. Ikki can use the same concept on a crowd of civilians looking for him was able to walk and weave through them undetected after reading their blindspots.

Expert Weapon Specialist: Ikki has shown skills in wielding kodachi, spears, and even archery. Enough that he been able to teach these skills to others. Stella said the reason why Ikki learned so many different fighting styles was to help him better make up for his lack of magic power.

Master Marksmanship: He has incredible skill when throwing projectiles, able to fire a small projectile with great precision. In a fight against Manabe, he flicked an eraser, which bounced off the ceiling and wedged it in-between his Gun-Shaped Device's hammer and percussion cap disabling it. Ikki had later kicked a lipstick tube knocking a knife out of a man's hand and kicked a small rock into Narukami's scabbard preventing Touka from using Raikiri.

High Intellect: Ikki is highly knowledgeable able to pick up on a lot of details even in the midst of battle. He also knows a lot about the inner workings and strong points of the human body, letting him improve Ayase's stance so she could use her feminine build to improve her Ayatsuji Itto-ryu. Ikki can also figure out most opponents' fighting styles, abilities, and strengths after fighting against them: figuring out Kuraudo's Marginal Counter, the Trackless Step, and even the rare causation manipulation of Amane. In battle, he tries to outsmart his opponents, which is highlighted as he was able to defeat Iris Ascarid, the 4th Ranked Blazer without being in danger.

Insight: As a result of being neglected over the years, Ikki has mastered the skills to see through his opponent's techniques by observation. He can read his opponent's next move simply through their muscle movement. Ikki's insight has even allowed him to properly sense how dangerous someone really is on the first meeting, such as being able to tell that Amane Shinomiya was more dangerous than he appeared, something few others notice.


 * Perfect Vision : Ikki is able to see through his opponents through grasping their fighting styles using his incredible insight to grasp their personalities and tendencies. Using this, it was possible for him to figure out their thought process and predict their moves in advance. It's as though Ikki is able to see everything about the person in question.


 * Blade Steal : Derived from his Perfect Vision, Ikki is able to use his great insight to analyze and steal his opponent's techniques, then further improve it with his swordsmanship. According to him, he is able to grasp most syles after a minute of exchanges and seconds to surpass it, it isn't limited to sword styles and applies to other styles. As soon as he is able to understand sword styles enough, Ikki is shown to be able to grasp their deepest secrets, even reproduce their advanced techniques though he has never seen it before and trained in it as shown when he learned Ten'i Muhou through training with Ayase.

Complete Body Control: Ikki can control his body at will, as a result of his training and is able to perform various superhuman feats: being able to turn off his other sense as he had transferred the acuity of his color sense to his motion perception to better read his opponent's moves. It is also the basis for his Secret Swords, Ittou Shura, and Ittou Rasetsu. Having stolen Edelweiss' Swordsmanship, his control had been sharpened to where he could even manually beat his heart. He sharpened his control after his warmup for his rematch against Stella, Ikki was able to see the strand of her hair, hear his bloodstream, understand all his muscles, and count the dust on his skin.

Magic Control: Ikki has enough control over his magic to be able to consciously use mana emission, a technique that is able to accelerate a person's movements, which all Blazers are able to use unconsciously. As a result of his low magic, he doesn't use it, though if he does choose to use it, then he can do so twice before running out of magic. After his training with Edelweiss, Ikki greatly improved his magic control, letting him utilize the same mana defense as other Blazers to such a degree that he could block a strike from Edelweiss and improved his usage of Ittou Shura. Having better control of his magic has allowed Ikki to better use Ittou Rasetsu, through pouring power into the needed parts instead of his whole body and pouring the excess power, which would've damaged him into Intetsu letting him continue fighting without the usual backlash.

Device
Intetsu (陰鉄, Shadow Iron): Ikki's Device takes form as a raven black katana. It is called forth at times whenever using the command: Come Forth, Intetsu.
 * Ittou Shura (一刀修羅, Single-Bladed Shura): Ikki's Noble Art and strongest technique. Through amassing all of his bodies' vigor and stamina as well as ignoring his natural survival instincts, Ikki is able to bring out his full power, then he further magnifies it using his Doubling Physical Powers granting him tremendous power for one minute. Training with Edelweiss to improve his magic control, he was able to improve his Ittou Shura but hasn't yet shown to what degree.


 * Ittou Rasetsu (一刀羅刹, Single-Bladed Rakshasa): An improved version of Ittou Shura, in which Ikki shuts down all his five senses and his bodies' functions for as well as mustering all of his strength for one second instead of one minute boosting his power a hundred-fold, but this could be used for one swing. Although the burden that it puts on him is far greater than Ittou Shura since it forced him to remain in bed for a week after using it for the first time. Having improved his magic control, Ikki could concentrate the power granted to the parts needed, while the excess power was focused on Intetsu.

Trivia

This lets Ikki fix himself after Nameless Glory had attempted to make him fail.
