YMMV / Karneval

  • Ear Worm: The anime adaptions ending theme, "Reason"
  • Ho Yay : Between Gareki and Nai
    • Gareki frequently blushes whenever Nai pouts or gives one of those Puppy dog eyes moments. He is also fiercely protective of the innocent Nai from the elements and villains of the cruel and evil world.
    • Much like Hinoe from Natsume's Book of Friends, Eva dislikes men and prefers the cute softness of girls, like Tsukumo.
    • When Gareki wins him a bracelet from a shooting game in Karasuna, Yogi responds with, "You're so cool, Gareki-kun. You must be popular with the girls. I got red just looking at you."
      • Not to mention he still wears it in Chapter 15...
    • Hirato with Akari. Hirato tries to woo/tease Akari with every chance he get. It's not even subtle.
  • Iron Woobie: Gareki. The guy really did have a terrible childhood.
  • Nightmare Fuel: OH GOOD GOD!
  • Tear Jerker: After Yotaka is killed in front of her eyes, Tsubame breaks down and loses the will to live, begging Yogi to kill her too as she cannot stand to be alone. She then offers herself to Circus as a test subject, knowing she will have to undergo horrific experiments and a great deal of pain. She then visits her dying grandfather to say goodbye, and realizes that Gareki was stealing to pay for his medicine all this time.
    • Yogi's past, being the only survivor of Kafka's annihilation of Rimhakka. As a ten-year-old he witnesses his caretaker's being decapitated by varuga. He is then captured and experimented on together with the rest of the nation, but was the only one to make it through alive due to his royal genes (as the nation's prince). He finds himself in an unknown place, strapped to a surgery table, with scientists screaming and cheering around him as he is forced to watch a video where his little sister, Miumarie (who was his dearest person), is literary torn to shreds along with his home and Rimahakka's citizens. All while she was pleading for him to help her. The poor child understandably snaps and loses control over his powers, slaughtering the scientists. He is then found a few days later by Hirato and is brought to Circus, where he is once again experimented on and kept locked inside Akari's lab for an unknown amount of time. The event traumatized him so badly that he developed a Split Personality as well as giving him a Trauma-Induced Amnesia.
  • What The Hell, Casting Agency?: A lot of people were polarized when Greg Ayres was selected to voice Gareki in the English dub, with the detractors saying that it doesn't sound right at all compared to the Japanese performance.
