The Imaginary Friend is a minor character in Winter Voices. Similar to The Heroine taking the form of an enemy, Imaginary Friend's appearance changed throughout the game. They can be summoned using the skill Imaginary Friend on the Social path.
Imaginary Friend is genderless, though the player can give it a gendered name. It can be interpreted as a manifestation of The Heroine's loneliness. Like The Heroine, it can be sarcastic, friendly, melodramatic, and has a highly malleable personality and character.
Taking to The Heroine's imaginary friend can provide various bonuses, such as increase Max Energy, Movement Points, Psychic Points or other benefits. The Imaginary Friend is relatively frail, though can be strengthened and healed using skills from the Support and Protection branches.
