Code:Emperor was the most powerful special power user. He was also one of the founders of Eden. His special power was The Seven Flames of Purgatory.
Appearance
Nobody really knows what Code:Emperor's adult form looks like, besides the three other Founders, who have presumably seen his true form.
Personality
He acts, as his epithet says, like an emperor and expects to be treated that way. He has a short temper, and will burn anyone who opposes him. However, in the Shibuya mansion he showed a soft side to him and even developed a crush on Rui Hachioji.
Background
During the Meiji Era, he, along with Heike and the other founders, created Eden. At some point, he was the founder of Kibou High, which served as a school for power users to be made in to soldiers.
When he learned about the power of the negation, he inmedietly ordered all Rare Kinds to sever their bonds with power users, but both sides were unwilling to leave each other. After many failed attempts of persuasion, he lost his temper and set out to burn all the rare kinds. That day became known as December 32.
History
Fire Ball Form
Oogami is the only one that can control the Emperor's power. Emperor takes the form of a candle flame. He is currently on the quest of finding everybody's weaknesses. Interestingly, underneath his fearsome facade, he is a very gentle person who cries when he reads sad stories. Also, he develops a crush on Rui and falls in love with her voice as well.
Code Emperor's original form
In chapter 103, Code:Emperor appears in a form of a small boy. Since he is just a residual of soul, that form is the best he can do. He appeared again in the kid form in chapter 106.
In Chapter 109, it is shown that Code:Emperor starts to remember Heike. He recognised Heike, and remembered that he was one of the people, along with Heike to build Eden. He couldn't recognise Heike earlier because of his previous flame form.
In chapter 110 and 111, we are told that Code:Emperor, Heike, and Sakura's real mother founded Eden. In chapter 134, he supposedly gave himself to save Ogami from Toki's attack, although he reappeared to show that he wasn't dead.
Abilities/Powers
Emperor has the Seven Flames of Purgatory, four of which have been seen.
