Sword Art Online is a highly-popular anime based on the concept of MMORPGs (Massive-Multiplayer Online Role Playing Games) becoming virtual-reality games in the near future that mimic real, waking life. Many fans of the show laud the complex story elements, plot twists, and oh, the feels that are present throughout the first season (and arguably best) of the show. Elements of video gaming mixed with human emotions are rampant in a virtual world where dying or losing a battle means you also die in real life.
Japanese pop singer, LiSA lends her talents to the opening of the first season and in her song, iconic of the series “Crossing Field”. If you have not seen the show I highly recommend it for anyone who likes gaming or anime.
