Clear along with his brothers α and α2, were designed to sing “Dye Music”, a song that could brainwash people into submission, thus dyeing their brains. His real name was nothing more than a serial number, R-2E-054, and he originally served under Toue, his master. Unfortunately, he ended up being a defective unit, and was to be disposed off until the man in charge of disposal adopted Clear and treated him like his own son.
This cosplayer looks familiar somehow, but I’m not completely sure. Perhaps someone here will recognize him? Thanks to Steph for sending this in!
