13 Sentinels: Aegis Rim

Synopsis

13 Sentinels is primarily set during a fictionalized version of 1985 in the Shōwa period, but also jumps between 1945 during the later years of World War II, 2025, 2065, and the distant future of 2105. The story follows the perspective of thirteen characters. While several characters are native to the 1980s period, several come from either the future or the era of World War II. The storyline is split between these characters, and by following each the player aims to avert a disastrous future for mankind. A recurring location is Sakura High School, which multiple characters attend across different time periods. The story is told in a non-linear format, switching both between different protagonists and the events of the final battle against an army of Kaiju, otherwise known as the "Deimos", giant monsters who arrive in 1985 and attack Japan. Each of the thirteen protagonist's arcs culminate in summoning a Sentinel, a mecha designed to fight the Deimos which also has the ability to travel between different eras. [Wikipedia]
