Doragu

is a prisoner at Hōzuki Castle.

Personality
Doragu is an imposing individual. During his time at Hōzuki Castle, he developed a reputation that allowed him to rise to prominence among other criminals, who eventually came to obey his orders and take his lead. His rise was aided by his information trading, making himself valuable to others, while at the same time using it to have others carry out tasks for him.

Mujina Bandits Arc
When Boruto and Mitsuki's plan to have Kokuri transferred to their cell was blocked by Benga, they decided to dig up information they could use to pressure him. Arai took them to meet Doragu, who he believed would have that sort of information. Doragu confirmed it, and while interested in creating trouble for Benga, he couldn't offer the information freely. He attempted to have Boruto's sentence extended by putting him in a situation where he'd be caught stealing the bulb of the prison's lighthouse, but Boruto was able to evade capture, so Doragu shared that Benga took many bribes.
