YMMV: Irisu Syndrome!

  • Ear Worm - The music is extremely catchy even as it's horrifying in and of itself. The author has placed high bitrate versions here.
  • Epileptic Trees - What the hell is with the black-red eyes on the bunny drawing in The Stinger? Why is Irisu smiling when you get to level 100 in Metsu? Why does Uuji see red eyes in his dream, too?
  • Fridge Horror - Evidence of Irisu appears in the background of some pictures - her ears are in the background of the first CG, and her sock is laying next to the group in the second.
    • The main menu's Irisu picture. Notice how she's only wearing one sock, carrying the other, and the heel and toes are blood-red? With no explanation whatsoever (until you unlock Metsu)? The Irisu in this image is in the process of murdering the íThree Amigos!.
    • The 100k Stinger has one. It's not an X with eyes below it. IT'S A RABBIT LOOKING FROM THE BOTTOM OF THE PAGE!
      • From Bad to Worse: Uutarou is the name of the bunny that was killed when she was little. U-tarou is another way of writing Uutarou. The black bunny image? U-tarou.png!
      • In fact, just look at the title. The very last character has a bunny with unnervingly red eyes. But that's not the main focus right now. Look at the exclamation mark right next to it. Notice how it looks like Irisu's sock straightened out? The same sock that she uses as a murder weapon?
    • For some more fun, look at what happens when you mouse over the bunny in Metsu Mode's menu. Now look at the bunny suicide picture. The íThree Amigos! are screwed. Just according to Uuji's plan.
    • Now that the English fan translation is out, just about everything. Bonus points for the normal-mode song titles, which are all descriptions of things that someone who is well, WELL past the Despair Event Horizon might say. "About 10 Hours Looking at the Ceiling," "I Didn't Talk to Anyone Again Today" and "Zero Communication".
  • Nightmare Fuel - That cute, bunny obsessed Shrinking Violet? Actually just one bad day away from a murderous rampage. That dopey loner hiding in the corner of the class drawing comics? A manipulative psychopath who thinks being murdered is romantic.
  • The Woobie / Broken Bird - Irisu might be plotting to murder two college students for committing the ultimate sin of getting close to the boy she's never spoken to, but it's hard not to feel sad for her, especially once you finish Metsu and realize what caused her Start of Darkness. Especially in the best ending, when she rises above everything that's happened and becomes friends with everyone.
