A otaku is a person, usually male, watches SERIOUS anime. They usually stay in the comfort of their home but come out when there are expos. If they do reach these expos, he/she will
probably spend their whole life's allowance on: Squish pillows, manga, super rare colectibles, and chibi figures. When at home, they will have most of their job money put on
trying to hold on a
subscription to things like VRV or Funimation (also Crunchyroll!). A otaku ranges from 5 years old (keep on watchin' Pokemon.), to mature level, which is like 17 or older.
