It looks like you're referring to the phrase — likely from the IJIRARE: Fukushuu horror visual novel series (often shortened to Ijirare or Ijirare: Revenge ).
For fans of "Psycho-Pass," "Death Note," and "Tokyo Ghoul."
(Visual: Black screen with text overlay or manga panels) Text: "If you think 'Fukushuu' means the victim gets revenge... you are wrong." Voiceover: "I just finished Ijirare , and I need a shower. This isn't a power fantasy; it's a tragedy. It’s the most stressful manga I’ve read this year. If you like happy endings, avoid this. If you like watching a train wreck in slow motion, it’s a must-read."
Ijirare: Fukushuu is a psychological horror visual novel developed by Tachi . The player controls a bullied high school student who, after a near-death experience, gains the ability to see and manipulate "fears" hidden in the hearts of others. Seeking revenge on four classmates who tormented them, the protagonist uses these newfound powers — and a mysterious notebook that records sins — to systematically destroy each bully's psyche through personalized, reality-warping nightmares.
