Akuma wears a symbol on his back, this symbol comes from the Japanese kanji meaning, 'ten'. The symbol itself comes from the Chinese language, and it was later adapted by the Japanese. It means several things as Japanese words often do, including: 'day', 'sky', 'heaven', 'beyond human', 'invincible', 'more than man' and 'ten'. It is synonymous with 'Immortal'. It basically means what Capcom has always conveyed, that Akuma is no longer human. In folklore, whenever the character 'ten' appears on a person's forehead, it means that that person is immortal. Capcom, for clarities sake, placed the symbol on the back of his gai.
