Redo of Healer memes stem from the dark fantasy light novel and anime series 'Kaifuku Jutsushi no Yarinaoshi.' Known for its extreme revenge plot, the memes primarily focus on the protagonist Keyaru (later Keyarga) and his unsettlingly calm demeanor during pivotal 'Heal' moments. The most famous template involves Keyaru offering a choice to a defeated enemy, often captioned with 'Which do you prefer?' or simply the word 'Heal.' These memes are frequently used in the anime community to signal a dark turn in a conversation, a moment of poetic justice, or to mock the series' controversial and over-the-top nature.
