"Antichlorobenzene" was first uploaded on September 19 at 3:55 AM (following the Benzene Series' pattern of videos being uploaded at the same time each year). It's a "reply" song to Owata-P's other hit song "Paradichlorobenzene". It only took one day (September 20) for "Antichlorobenzene" to reach Hall of Fame (exceeding 100,000 views), and reached 1 million views within a year (May 17, 2011)
