Additionally, pre-orders are available now at Japanese retailers such as Amazon Japan. Here is the description of the game from its product listings:
An adventure game where a group of cheerful girls enjoy a laid-back, girls-only survival life in Tokyo’s Akihabara. Five girls in a long-abandoned Akihabara. With no one else around, the girls must befriend and help each other while living happy days. From the all-necessary tasty cooking to bathing and the occasional relaxation time, the girls are cheerful and honest in any situation, and enjoy themselves to the fullest.
To All of Mankind is due out for PlayStation 4 and Switch on May 30 in Japan.
