YMMV: Cage of Eden

  • Angst? What Angst?: A lot of the times, the characters will get a little upset but move on rather quickly from the tragic, stressful events around them like discovering that your first love got gang raped to death, finding out your best friend turned into a mass murderer or Zaji dying. Justified in how the characters are constantly in danger and can't afford to dwell too much on the negative things.
  • Epileptic Trees: Everything in the series.
  • Fan-Preferred Couple: If the forums of various sites are to be believed, then Akira/Rion is by far the most popular pairing, and for good reason, due to their willingness to protect and take care of each other, no matter what happens. Akira/Mami seems to be gaining popularity quickly, though.
  • Fetish Retardant: How some feel about the fanservice.
  • Ho Yay: Kouhei really wants to find Akira. He also states that while he can't bear to show himself in front of Akira anymore, he will protect him from the shadows.
    • Yarai and Akira have a bit of this, too. In Chapter 141, Yarai actually cries because he doesn't want to kill Akira, but Nishikiori won't save Kurusu-sensei if he doesn't.
  • Moral Event Horizon: Kouhei, up to then one of the nicer characters, kills a girl on the mere suspicion that she saw him stab the pilot.
    • Nishikiori jumps over the line with every appearance. It really says something when the nicest thing he's done is send a bunch of kids on a suicide mission.
  • Nightmare Fuel: Being stuck on an uninhabited, mysterious island with every large and dangerous prehistoric species out to eat or maim you is not a Happy Fun Time. So you can bet that the series is full of this.
    • That's not even counting all the humans on the island either. One of the main themes of the manga is that wild beasts aren't the only animals to be scared of.
    • This creature qualifies
      • This looks more like a demon than an extinct animal
    • Nishikiori's brainwashed slaves, who keep serving him despite all logic and reason.
  • Squick: In general, the manga doesn't pull any punches in showing exactly what teethnote  bigger than your head can do to you...
    • Or big falls.
  • Tear Jerker: Several moments in the series.
    • Akira's mother dealing with her son's presumed death.
  • Too Cool to Live: Zaji
