Also known as: 打破次元壁
Someone or something goes through the medium they are presented in, such a coming out of a page. This may be a Fourth Wall break, but does not have to be -- the medium being passed through may be an object depicted in the work, rather than being the work itself. For tagging purposes this also includes things that are not a typically considered a medium on their own, such as a coming out of a screen. This also includes reaching "into" the medium, eg post #2130515.
