Dolce

 is a person from the slums Ryoma hired as a security guard.

Personality
Dolce is just a really nice dude who likes to help! He takes care of the less fortunate youth, he's ready to put in the effort where his skills are needed, and very likely has a saucy side in his spare time under the pseudonym Gabbana.￼

Trivia

 * Dolce has a side story in the web novel that did not make it into the light novel that would have probably been included at the end of the fourth light novel.
