Robin, also known as the "Blonde Boy" (金髪の少年 Kinpatsu no Shonen), is a seemingly undead boy that Aya encounters in the mansion. 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. Later on, after she was almost choked by a subject, Aya faints and Robin takes her out of the room. After she wakes up, he tries to convince her to escape from the mansion, which she refuses. After that, Maria appears and throws knives at him. In the remake, Aya touches him after he passes out which reveals a little bit of his backstory. Prior to working at the Drevis mansion, his parents and younger sister passed away in an accident. 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. As Robin walks away after that encounter, he remarks that it's ridiculous for Alfred to think that Aya could replace his little sister. However, he came to grow protective over Aya as he saw that she held similarities towards his sister. Unfortunately, he would become a experiment for Alfred thus why his eye is missing and face is disfigured. He did survive this experiment, thanks to Monika's ghost, and instructed him to take care of her daughter. He agreed, as the memory ends there and Aya continues on her path towards rescuing her father. He is not seen again until one of the endings. After Maria fails to kill Alfred by throwing multiple knives at him when he tried to kill Aya, he gets up and tries to kill them both. Robin saves them by incapacitating Alfred just in the nick of time. Later in the story, before Aya and Maria are preparing to leave, Robin says Aya has no need to thank him and reveals it was her mother who had sent him to make sure she wasn't hurt and says he had no intention to be injured or to have scared her earlier. He tells Aya to not be sad, because her mother is watching over her. Robin continues to explain he must now set fire to the mansion to get rid of any traces of her father's work to prevent the tragedy from happening again, and asks Aya to remember her father's victims since their existence would be forgotten otherwise. Aya agrees, and as the mansion begins to burn Robin kisses Aya on the forehead and says "Goodbye Aya. May you be smiled upon." This is a charm previously shown to also be given to Aya earlier by her mother before she died. It is a reference to this. Aya and Maria leave, and the mansion and Robin are seemingly consumed by the flames along with the other reanimated corpses in the mansion. Robin is a young boy, with blonde hair, and light brown eyes, he has bandages bounded around his head that conceals his right eye. One of his eye is missing that was taken away by Aya's father as a child. His attire consists of a white collared shirt and brown pants, with straps over his shoulders. Robin has a rather lanky build, though he is stronger than he looks. His expression usually remains stoic throughout the game. He is a quiet and a slightly stoic young man. He knows what he has to do and stays focused. He is thankful for Aya's help and wants all of the victims to be remembered. He seems more mature for his age (possibly 13-14 years old), maybe due to what he has experienced since coming to work for the Drevis family.

We imagine his voice to sound similar to the English voice of Killua from HunterXHunter. Stoic, focused, and having a mid ranged voice. We do already have someone in mind to play him, but we would also like to hear other candidates as well.
