Keigo Ugachi

Keigo Ugachi is an OVA-exclusive character and the former leader of Goreless Peace.

Appearance
Keigo is normally seen wearing a white suit with a black shirt, in his breastpocket a black handkerchief. He also has dirty, white hair.

Personality
Keigo talks a lot about sound, mentioning that the world sounds "cacophonic" or harsh-sounding. He prefers no sound, silence. He also mentions this when Senji is about to kill him, that he wants Senji to send him to a place of no sound.

History
Very little is known about Keigo, but his most important trait is that he is the leader of Goreless Peace, a local mafia gang. They claim to be protectors, while the only thing they do is harass the people.

OVA: Red Knife Wielder
Keigo tries to get Senji Kiyomasa to join his gang (Goreless Peace), but Senji refuses. Keigo is infuriated by this and commences an attack on Senji's friends, killing Izuru and Hinata. Senji then goes after him and eventually is trapped in his Branch of Sin. Senji attempted to get free, only to be caught once again. Domon then entered to assist Senji, but Keigo trapped him as well, wounded him critically in the process. Angered by this, Senji manages to extend his Crow Claw and stabs Keigo through the chest. Keigo tells Senji to finish him off, which Senji is glad to comply with, however Domon interrupts, telling Senji that he cannot kill Keigo as then he'd be no better than him. Senji raises his Crow Claw to bring down on Keigo, but stops at the last second as he notices that Keigo fearfully flinched. Senji passes out, and Keigo is arrested.

Abilities
Superb Speed:  Keigo was so fast that he was able to completely get past Senji's defences and within hearing distance of his heart before he could react. It is unknown whether or not this has something to do with his BoS.

Special Hearing (Possibly): He was able to tell that Senji had a BoS just by listening to his heart & comparing it with the sound his own makes. It is not known whether this is unique to him or not.

Branch of Sin: Keigo has been infected with the Nameless Worm and gained the ability to freely move his blood out of his body.

Branch of Sin: Wire Lyre: Wire Lyre is a web consisting out of blood that can entangle and even severely injure his opponents.

Trivia

 * He may have existed at some point in time, as Toto Sakigami was shown using some variation of his Branch of Sin in the manga.
 * Given that he was arrested, it's likely that he was sent to Deadman Wonderland afterwards. However, he was never spoken of in any capacity by Senji or other Deadmen, thus his ultimate fate is not known.
 * Keigo is the only antagonist who lost to Senji that wasn't killed.
