He is not seen again until one of the endings. He agreed, as the memory ends there and Aya continues on her path towards rescuing her father. He did survive this experiment, thanks to Monika's ghost, and instructed him to take care of her daughter. Unfortunately, he would become a experiment for Alfred thus why his eye is missing and face is disfigured. However, he came to grow protective over Aya as he saw that she held similarities towards his sister. As Robin walks away after that encounter, he remarks that it's ridiculous for Alfred to think that Aya could replace his little sister. Afterwards, he was hired by Alfred who told him to think of the household as his family, and that Aya would be his new sister. Prior to working at the Drevis mansion, his parents and younger sister passed away in an accident. In the remake, Aya touches him after he passes out which reveals a little bit of his backstory. After that, Maria appears and throws knives at him. After she wakes up, he tries to convince her to escape from the mansion, which she refuses. Later on, after she was almost choked by a subject, Aya faints and Robin takes her out of the room. His intentions seem to be good when she first meets him offering to help her by showing her the way, but Aya is shocked when she realizes half his face has been horribly burned and runs away, terrified. Robin, also known as the ' Blonde Boy' (й‡‘й«ЄгЃ®е°‘е№ґ Kinpatsu no Shonen), is a seemingly undead boy that Aya encounters in the mansion.
