Ghost of Yōtei follows Atsu, a wandering mercenary who returns to Ezo — modern-day Hokkaido — in 1603 to hunt down the Yōtei Six, the band led by the samurai lord Nariaki Saito who slaughtered her family sixteen years earlier. Her revenge carries her across an island modelled on Hokkaido, from the grasslands at Mount Yōtei's foot to the frozen north and the Matsumae clan's castle in the south.
This route follows the game's regions and their real counterparts: the Yotei Grasslands around Lake Shikotsu, the Ishikari Plain, the Ainu country of the Nayoro Wilds, the Kitsune's Teshio Ridge, and the Tokachi Range, with Mount Yōtei and Matsumae Castle as its fixed points.
In November 1274 a Mongol and Korean fleet landed on Tsushima, a mountainous Japanese island halfway to Korea, and overwhelmed its few defenders. Sucker Punch's 2020 game drops a fictional samurai, Jin Sakai, into that invasion: he survives the massacre on the beach and turns into "the Ghost", a guerrilla who breaks the samurai code to drive the invaders out.
The designers visited Tsushima twice but did not copy it one to one. This route visits the real places behind the game's opening battle, its castle and its shrines, most of them featured in the island's own guide for players. Jin, his clan and his battles are fiction; the landing, the fortress and the mountains are not.
