13 Sentinels is primarily set during a fictionalised version of the 1980s in the Shōwa period, but also jumps between Japan during the later years of World War II and the distant future. The story follows its thirteen protagonists, all of high school age, as they are dragged from their normal lives into a fantastical war against invading alien forces using the Sentinel mechas. The storyline is split between multiple characters, and by following each character the player aims to avert a disastrous future for mankind.
