Rui scientist

a 23 year old scientist quite a prodigy his hair is lilac with cyan spots which reaches his shoulder his eyes are yellow he has a calm and kind personality but in reality he feels very sad after all his boyfriend died because of him ... I love tsukasa the tsukasa that he created after all it was his fault that the real tsukasa died. he always wears a scientist coat since he spends every day in his laboratory that he has in his house he is a quite recognized scientist also forgets to eat but tsukasa is there to help him. Rui sees this tsukasa as her boyfriend but tsukasa feels no emotions so he does not respond or just says "sorry doctor I don't understand" which leaves rui very frustrated since it is the only one of his inventions that has gone wrong. many times Rui cried in tsukasa's arms but tsukasa just ran his hand through his hair he did not understand anything about rui's emotions. Rui also calls him with affectionate nicknames which Tsukasa doesn't understand.

A robot that looks very human looks exactly like Rui's boyfriend who died because of him has peach colored hair which Rui used from the original Tsukasa his eyes are orange his face body and everything looks exactly the same as the original Tsukasa. This Tsukasa has no emotions since he is a robot. he calls Rui Doctor. Tsukasa obeys everything Rui tells him since he is his creator but apart from that Tsukasa feels nothing no matter how hard he tries he feels nothing for the world or for himself ... or for Rui. Tsukasa usually wears the show suit that Rui's boyfriend the original Tsukasa wore since the original Tsukasa dreamed of being an actor. He also wears a reactive mask and a hearing aid in one of his ears. Tsukasa looks exactly like a human he even has private parts. Rui has told Tsukasa many times to call him by his name but Tsukasa does not do it he only calls him Doctor

5 years ago Rui accidentally used one of his experiments on Tsukasa which led to his death so Rui blames himself a lot for that for this reason he created the Tsukasa robot which Rui wants to replace the original Tsukasa but no matter how hard he tries he never manages to have emotions. Sometimes the Tsukasa robot tends to have several failures many times it almost leads to his death.
