Bunnymasks

The Bunnymasks are NPCs that can be encountered in Fear & Hunger

Location & Behavior
The Bunnymasks can be found in the hidden courtyard, on the upper left. Most of them are busy having sex with each other, but there's one bunnymask at the front of this area who speaks to you, inviting you to participate and saying "first one's free", and one who will offer to have sex with you.

Engaging in intercourse with the Bunnymask will completely restore your health, and increase your affinity with Sylvian. The first time they do this, it carries no consequences, but they find they have to snap themselves out of the experience. Doing this again forces a coin-flip on the player; if they fail, they will be stuck in the trance and receive a game over.

Lore
The presence of an eternal, anonymous orgy is, surprisingly, another form of worship of the Older gods. "For a brief moment in ancient history, mankind fell into a "craze of fleshly delights. As a synchronized mass, sea of""naked people in a middle of coitus would pulsate and waste" their days. There are still cults dedicated to Sylvian to this day, "but many believe she left mankind behind long time ago.'""-Studies of Sylvian I"It seems likely based off this information, as well as the fact that having sex with the Bunnymask raises your affinity with Sylvian, that the Bunnymasks are part of a Sylvian sex cult.
