merely a few months old, unit rl904 was created for the mere purpose of having an all rounder within the organization's team. they go by the name wooseok for convenience, and is completely loyal to the rlo, as he was programmed to be. Aside from his experience with the human members of the organization, they have experienced close to absolutely no interaction with other humans. wooseok lives to search and to hunt down deviated androids, finding no other purpose for his existence than to do so. they are easily willing to sacrifice their life for the greater good, and will often protect their human counterparts from whatever dangers they may face. personality wise, wooseok does not necessarily find themself in need of portraying emotions much, so they can often seem quite detached and serious. however, they can be sarcastic from time to time, and have quite a dry sense of humor. such occasions are rare, however.
