Ame no Marginal -Rain Marginal is the latest short, serious visual novel created by Tomo Kataoka, the author of Narcissu 1st & 2nd. The game is available for Windows and falls under the Adventure subcategory of Games. In this game, the protagonist finds himself in a mysterious world after getting off an elevator. The world is characterized by endless rainfall, weathered flagstones, and an empty population. The only person present is a girl named Rin, who claims to be the lone mistress of this rainy world. Time seems to have stopped in this world, except for the continuous rainfall. Rin urges the protagonist to leave and find a way out of the world.

The game also includes a copy of Narcissu 1st and a short bonus episode. The game can be played in either English or Japanese, but there is no way to change the language within the game due to technical constraints. However, it is possible to change the region for the game, as documented in the provided link. It should be noted that to play the game in Japanese, the Windows installation needs to be set to handle non-unicode text as Japanese.
