Kouji

Known as the scarred Re-Code:03 also granted title "The God of Destruction", Kouji is highly praised for his combat skills and was the one to "kill" Nenene.

Personality
A man who believes only in fighting the strongest opponents around and that weak people aren't worthy to be killed by him. When he fought against the Code:Breakers, he often used his powers to block off their abilities, before pushing them aside, while saying that they should live on if they have families and friends to look after.

Kouji is a very calm person who does not show much emotion easily. Despite his calm personality, he can go into a sadistic battle rampage when he finds a strong opponent.

He finds bashfulness to be a sign of femininity, and believes that women should not be on the battlefield.

Background
Not much is known about his background, although he presumably was a member of the Re-Codes long before Rui.

He found Rui after Ogami attacked her family, still alive, and took care of her. When he was about to leave her, after she awoke, she insisted on following him, even cutting off her long hair to discard her femininity.

History
One of the original Re-Codes that worked with Rui and Yukihina, he fights alongside "The One Being Sought" to get Pandora's Box, though it seems that he cares for "The One Being Sought" when he said that he would remain "his buddy" till he dies. Interestingly, Kouji was also sent to protect Ogami by "The One Being Sought" when Code:Emperor revives. Kouji said that it was 'His' last wish.

In chapter 97, Kouji told Ogami that one of Ogami and Sakura's classmates was actually a Code:Name in disguise. He also said that particular Code:Name has always been watching them, ever since the beginning.

In chapter 117, it is revealed that his lost form is a wolf. He still retains his scar in lost form.

It was mentioned by Yukihana that it had been years since he had seen Kouji's lost form, showing that Kouji is really strong, as he doesnt need to overuse his powers.

Kibou Festival
During the Kibou Festival, he accompanies Rui, telling her at one point that it was impossible for her to hide in her dress, which was a Victorian-styled, floor-length dress.

During the ceremony, it is revealed that he defeated his Deadly Sin long ago.

Powers/Abilities
Enhanced/Superhuman Endurance: Kouji has very high defensive power, with or without his special power. His physical durability rate is extremely high, enabling him to take the full force of Toki's Gauss Cannon and not die, still standing as if it was nothing, and continue on fighting with no signs of weakness in his performance.

Enhanced Speed: Kouji has shown amazing feats of speed, being able to relentlessly attack and pursue Toki in hand-to-hand combat while the latter was forced on the defensive. He is has shown himself able to match Aoba's speed and block her roundhouse kick.

Enhanced Strength: Kouji has shown strength far surpassing an average human, able to smash the ground and steel alike with his bare punches. Even in his lost form, he was still capable of picking up and carrying Yuuki to the hospital.

Expert Hand-To-Hand Combatant: Kouji has shown some skill in hand-to-hand combat, able to overwhelm Toki in that field with relative ease while not using his powers for that time.

Advanced control over the Force of Life: Kouji possesses advanced control over his Force of Life, the source of special powers, allowing him to stop his body from aging.

Special Power
Void

Kouji's power is "void", which enables him to generate wind and bend the very air around him which enables him to pierce and crush things within the vicinity of him. This can also as well act as defense, as he can make shields, vacuums and defensive barriers. It was said by the saint fighters of eden that kouji's "void" is so strong that even though he has only one power he can fight evenly with the code:Names.

Techniques
Vacuum: Kouji creates a temporary vacuum around him, stripping the area of air and negating abilities and powers that rely on air.

Crash Down: Kouji uses intense air pressure that comes down from above and crushes his enemy against the ground.

Aerial Wall: Kouji creates a wall made of air to protect himself.

Kamikaze (Divine Wind): Kouji creates a defensive barrier made of wind to protect himself. This technique can also be used as a attack. Shown in chapter 117 when he used it to rip apart the clothes of the various enemies he was facing at the time and defeated them.

Kamiarashi (Divine Storm): Kouji's most powerful attack shown thus far, he creates a vacuum storm radiating from his body, reflecting attacks back at his opponent and slicing everything that comes in contact with the wind. It is powerful enough to overwhelm Toki's Gauss Cannon with relative ease.

Toki Fujiwara
Toki has been searching for him for a long time to exact revenge for the "death" of his sister Nenene. He is so obsessed with him, that when Kouji makes his appearance, Toki warns the others to back away from "his prey". Toki reveals during that fight that he gave up everything so that he could defeat him, not giving up until he could get even one scratch on him.

In return, Kouji saw Toki as a person "worth destroying," although he allows Toki to live upon seeing Sakura. He also took the blame for Nenene's death, despite not being her killer, as he wished to prevent a chain of revenge.

Rui Hachiouji
Kouji used to work together with her as a fellow Re-Code. He mentioned to Toki that he once made a promise to Rui before she left that he will never lose to anyone. It is suggested that their relationship was more than just being comrades, possibly romantic.

Yukihina
Although their relationship has not been seen very often, it seems that they have a tight comradeship, as they are often seen working together. Yukihina is the only one capable of understanding Kouji in his lost form.
