Danmaku-or Danmu-is a comment-sharing system constituting a specific viewing state. Videos are directly covered with users' comments from time to time. Such frequently changing viewing contexts have never been studied thoroughly, and this study aims to investigate this novel phenomenon with Deleuze's Rhizome philosophy. Rhizomatic thinking focuses on the "assemblages" of physical objects and metaphysical concepts as well as how they are "becoming." In our conceptual framework, Danmaku films and the audience are both seen as "machines" through which the "affect" flows. The "affect" forms various rhythms, which energize the constant changing of the content in a video, inviting users to arouse instant sensation and aesthetic experiences.
