Monster Girl Quest

Monster Girl Quest is a 2011 eroge video game series developed by Japanese company ToroToro Resistance. The game is an RPG and visual novel hybrid that features different types of Monster Girls following the tales of Lukas journey to becoming a hero while defeating various female monsters. The game subsequently spawned memes, such as Hora Hora and Touch Fluffy Tail that reference various in-game elements.

Plot
The story follows the journey of Luka, a boy who believes in the possibility of coexistence between humans and monsters. Meanwhile, the goddess of Luka and the rest of their world, called Ilias, commands her worshipers to slay the lord of the monsters and monster girls. Luka, contrary to his goddess' commands, wishes for there to be peace as the monsters and humans have been in constant on-and-off wars for a thousand years.

Artists
Many different Japanese artists worked together to create the visuals for the game, including
Arekishi, D AM, Delphinus, pe, frfr, Irodori, Iwashi no Atama, Jingai Modoki, Kenkou Cross, Masha, Setoushi, Silk, Thomas, UN_DO and Xelvy. Many of these artists have previously done art in the Monster Girl genre, with Kenkou Cross being the artist and author of the Monster Girl Encyclopedia.

Touch Fluffy Tail
Touch Fluffy Tail is an action the player can perform in the first installment of the game when faced against Tamamo, one of the Four Heavenly Knights. If the player chooses to touch Tamamo's tail, Luka will succumb to the fluffiness and lose. In comparison to the average "game over" resulting in being assaulted and devoured by a monster girl, succumbing to a fluffy tail stood out to many players, resulting in Tamamo often being associated with the option in fan art or memes.
