Is saintia SHO canon? Essa é a pergunta que vamos responder e mostrar uma maneira simples de se lembrar dessa informação. Portanto, é essencial você conferir a matéria completamente.
So, it's very, explicitly obvious that Saintia Sho is set within the Classic Manga's world, functioning as a parallel story, and that the project derives from Masami Kurumada himself, who is greatly involved in the creative process as a supervisor. I can safely consider it canon as well.
