Mechademia is an annual English-language academic journal on Japanese pop culture and related topics. Each issue has its own theme, and volume 10's is "World Renewal." In theory, this includes not only the branching timelines and parallel worlds of games and anime such as "Higurashi no Naku Koro Ni" ("Higurashi When They Cry") and "Puella Magi Madoka Magica," but also the epochal 2011 Great East Japan Earthquake.
