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 uses his powers to block off their abilities, before pushing them aside, while saying stuff like they should live on if they have families and friends to look after.

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.

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 retain 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.

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.

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.
