Ray (レイ, Rei) is one of the main protagonists of The Promised Neverland. Unlike all the other children, he is not an orphan.
Ray has dark, somewhat messy hair that slightly cover's his left eye, he wears the standard white uniform. He has dark eyes and a slender appearance wearing usually a tired like look.
Ray is very logical and smart and is usually shown to read books by himself. He does not seem to be very attached to other children in the orphanage as he is seen to be willing to leave them behind to increase the chances of the trio to escape. According to data obtained by Sister Krone, his weakness is that he gives up easily.
Ray is extremely patient and cunning. He can remember everything since he's been born, so he's known about the demons and had been playing double agent with mama since age 6. Although Ray is extremely book smart he says that he never liked studying. The reason he did was to become top of the line food and devise a plan to escape with Norman and Emma.
Ray is shown to have been in the orphanage since a young age together with Norman and Emma. He learns about the demons from Emma and Norman and believes them immediately, because as he puts it "Norman would not tell such a stupid lie". The trio works together to find a way to escape from the orphanage. At the end of Chapter 12, it is revealed that Norman suspects him to be a spy for mama.
In Chapters 13 and 14, it is revealed that Ray is indeed Mama's spy, but is, in fact, working as a double-agent and became her spy as part of his plan to one day escape with the others, thus making him a double-agent who has been plotting against Mama all along.
