One of Benx' friends from early childhood, Artemian (simply called Arte by everyone) caught wind of secret things going on in his buddy's friend group, and eventually figured out the entire mystery of the agency all by himself. He was a very talented acrobat himself and swore to become a member of this mysterious group. At first, Eos would not have it, but Arte persuaded him hold an audition, where he could prove his worth. Arte's audition performance far exceeded what any of the agency members had expected, but Eos was still unsure, so Arte had to reveal his big secret: his superhuman strength! Like his brother Piet, Arte had been blessed with a marvelous superpower since birth that nobody could explain. With this added to the consideration, Arte was accepted as the agency's fifth member, and Eos' initial reservations quickly disappeared as they became best friends.

Arte's brother Piet, who can literally put knots into his legs and do all sorts of other crazy tricks, might have been the perfect person for Eos and the other agency members to get to know, but things didn't turn out that way - When Arte first met Eos and his friends during his auditions to join the agency, he was coming fresh out of a personal catastrophe: His boyfriend Sasha, a passionate Karate athlete, had just broken up with him. The reason: No matter how hard Sasha trained, he would never reach the level of fighting power Arte was naturally blessed with despite not training any martial art at all - dating someone with superhuman strength was simply too depressing for Sasha. Now meeting Eos and his friends, Arte was afraid the same might happen to them if they were to find out that his little brother was a literal piece of rubber who could outperform any contortionist with ease - so he kept silent about Piet and the existence of this miracle boy remained a secret to Eos and the agency folks. A secret that can be very hard for Arte to keep at times, since Piet loves to get into trouble and walk the thin line of keeping his powers somewhat under cover while having the most amount of fun with them.

Recently, Arte and Andrea have started dating, which constitutes the most significant romantic development within the crew since the agency was founded - but that's only because Ienge is so damn shy.
