Shiryu

Shiryuu of the Rain is a former Chief Guard of the Great Jail Impel Down, and a current prisoner of the place he once guarded. His name literally means "Method of Death" or "Death Axe" or "Death Dragon" in english.

Appearance
Although Shiryuu has not made a personal appearance, his silhouette was seen in a flashback. There, he was seen to have devil-like wings, like Magellan, along with an officer's hat that is similar to the one Domino wears. Shiryuu was also smoking a cigar.

Personality
Shiryuu seems to love to kill people. He massacred many prisoners within the walls of Impel Down, claiming them to be "trash". This behavior may be due to his hatred towards criminals, or that he may be a homicidal sociopath. Regardless, he was abusing his authority over the prisoners, similar to how Rob Lucci abused his CP9 permission of killing citizens for amusement.

Abilities and Powers
As former chief guard of Impel Down, Shiryuu has command over lower ranking employees of the fortress.

He was also said to have comparable strength to Chief Warden Magellan. However, since Magellan's work hours are limited by his diarrhoea, Shiryuu is considered more dangerous.

Shiryuu is seen to be holding a katana when slaughtering prisoners.

History
Though the guards of Impel Down have permission to kill prisoners for security reasons, Shiryuu has heavily abused that privilege, and killed many prisoners for his own pleasure. When confronted by Magellan, Shiryuu's abuse of his privilege was revealed and he was deemed to be a menace. For that, he was sentenced to Level 6 for life.
