Psychedelica of the Black Butterfly and the Ashen Hawk

Psychedelica of the Black Butterfly and Psychedelica of the Ashen Hawk are two otome visual novel video games developed by Otomate. They were published for PlayStation Vita by Idea Factory in Japan in 2015 and 2016, and by Aksys Games in North America and Europe in 2018. Intragames and Idea Factory released Black Butterfly for Microsoft Windows in 2018, and Ashen Hawk in 2019.

In the games, the player reads the stories and make decisions that affect the direction of the plot, leading to different endings. Black Butterfly follows an amnesiac woman who is forced to partake in the black butterfly hunt, and Ashen Hawk follows a woman who is thought to be a witch and therefore disguises herself as a boy and lives outside the town.

Gameplay
Black Butterfly and Ashen Hawk are visual novels in which the player reads through the story and makes choices such as what the player characters should say, affecting the direction of the plot and which of the games' endings the player ends up at. The games include an interactive flowchart, which the player can use to go back and try alternative choices and keep track of what they have done in the games. In addition to the main scenarios, there are side stories where the player learns more about the characters.

Plot
Black Butterfly follows an amnesiac woman who wakes up in a Western house and is attacked by monsters. She meets men in the house who similarly cannot remember their pasts, and the group is forced to partake in the black butterfly hunt to gather the kaleidoscope fragments the monsters possess.

Ashen Hawk follows a woman whose right eye turns red when she feels strong emotions; in her hometown, women with red eyes are considered witches, so she disguises herself as a boy and lives in a tower outside the town.
