A dark-haired young American cop who dislikes trouble-makers, which is ironic, since he seems to be one himself. His personality can switch from boisterous and inappropriate to serious and calm instantly. Though moody at times, he cares very much for the people around him. He is in love with Ryo, but has dated women in the past; in Dee's own words, he has several types of women he likes, but Ryo is the only and perfect man for him to love.

Dee may seem to be rude and intrusive, but he has a strict sense of honour that will not allow him to take advantage of anybody; however his parameters can often be well outside the norm. He claims to hate children but understands Bikky's motives well, often acting the part of the wicked uncle when Ryo tries to impose a bit of discipline upon the unruly boy. Dee is fiercely protective of both Carol and Bikky, and is well liked by the children who now live at the orphanage where he and his childhood friend Tommy grew up.

The surname 'Laytner' is made up; the name of the cop who found him in an alleyway was Jess Latener. Seeing him as a father figure even after he was revealed to be less than perfect, Dee was proud to take a similar name to the strict Jess. Dee is searching for stability in his life.
