Characters (Spoiler Free)

Macky Stingray
Macky is Sylia's little brother and made his first appearance in episode 6, where he impressed Nigel with his knowledge in machines. Sylia is especially fond of him as he was one of the few people who never deserted her. He is initially extremely obedient to Sylia and gets along well with her butler, Henderson, but as secrets unravel everybody's attitude changes. He helps the Knight Sabers out a lot, and has a crush on Nene.

Leon McNichol
Leon works for the AD Police -- the same place Nene works. Nene enjoys teasing him, manipulating his name to be "Leon-poo" or calling him "Leonardo" (it is ADV's English rendition of "Leon-chan", of which the "-chan" suffix is normally reserved for girls or young boys). He has a crush on Priss, but unfortunately for him, she hates the AD Police. However, this does not stop him from perservering and as they say, patience can move mountains. Or in this case, a stubborn female singer.

Dailey Wong
Another member of the AD Police, Dailey is often seen on duty with Leon. He, like Nene, also enjoys teasing Leon about various topics (namely his crush on Priss), making Leon rather irritated. He and Leon are always trying to beat the Knight Sabers to the Boomer scene. It is hinted that Dailey may have sexual preferences different to that of the normal male (to put it nicely).

Nigel Kirkland
Nigel is a highly trained mechanic and often helps out the Knight Sabers by repairing their hardsuits. He has grown rather close to Macky as Macky looks up to him like a role model. He shares a past that involves the Stingray family and Sylia seems to have a thing for Nigel, although initially he seems uninterested in her.

Brian J. Mason
Brian J. Mason, known more commonly as Mason, is the CEO of GENOM and also one of the "bad guys" working behind the scenes. He has devilish plots and reports to Quincy, who he secretly hates. He is a sly character and it becomes apparent later in the series that in the past he has been linked with the Stingray family.

Quincy Rosenkroitz
Quincy is the head of GENOM Corporation, a corporation reponsible for the maintenance of Boomers. His past is shrouded in mystery, but little by little more of who he is is revealed. He is a seemingly liveless shell, kept alive only by machines. He is also trying to catch the Knight Sabers.
