Famitsu has been providing a series of trailers for Spike Chunsoft's upcoming PlayStation 4 and PlayStation Vita RPG, Exist Archive: The Other Side of the Sky. These trailers each focuses on one of the game's twelve heroes, who were all made immortal and transported to the realm of Protolexa following an explosion in modern-day Tokyo caused by the dark god Yamatoga. So far, Famitsu has released trailers for the first five characters, which can be seen below.

The first trailer features the main protagonist, Kujo Kanata. Kujo has white hair and is the son of wealthy parents. He is also the fiancé of the second character, Ranze Miwakawa, their marriage arranged when they were both seven years old. Ranze is the daughter of the traditional leader of a large dojo in Tokyo.

The third character trailer is for Mayura Tsukishiro, the first character protagonist Kujo meets in Protolexa. Like Kujo, Mayura has white hair, which is apparently the result of an illness. She also has little memory of her life before coming to Protolexa. The fourth trailer features Tokihisa Kiriya, another person met by Kujo in Protolexa. He has an abrasive personality but apparently enjoys fishing as a hobby. The final trailer so far is for Koharu Nagi. Koharu attends the same high school in Tokyo as Kujo and Ranze and has a cheerful personality.

Exist Archive is developed by tri-Ace and due to be released for PlayStation 4 and PlayStation Vita in Japan on December 17, 2015. The game has not yet been announced for a western release.
