That's the tricky thing, with nothing 'official' stated, readers are left simply with what they can observe on the pages. It may be speculation and yet it's good if people are perceptive to looking more into what they are being shown on paper. That's important for the story overall, the key example being Yu under the impression he was in an orphanage - only it was some horrible experimentation facility :O yes facts are important, but also taking part in guessing what is really the case.
