I Transmigrated to Another World, and Only I Know the Anime

In this world, humanity faces threats from vicious beasts and demons from beyond the realms. That is when the profession of Spirit Master emerges in human society. Chen Shuo, who has transmigrated here, suddenly discovers that the beings contracted by this world's Spirit Masters are all characters from the novels and anime he watched before he transmigrated. Yet this world has no such novels or anime, making him the only person who knows these characters.
