In the game of O-To-Ko-Yo, kids will disappear.

A 25-minute short about a game of Hide and Seek? That has to be fun for the kids, right? Wrong.

Children wearing fox masks gather in an abandoned city after dark to participate in a ritualistic game of Hide and Seek. One boy has come looking for his younger sister, and a silent player in this round sure looks a lot like her. The rules are simple — if you lose, demons will take you away. And, as the night wears on and the streets light up, it becomes clear that the chilling rumours are not exaggerated...

Provides examples of:

  • All Myths Are True
  • All There in the Manual: The official website is the only place where you'll learn everyone's names—only four are revealed in-movie.
  • And Then John Was a Zombie
  • Back-to-Back Badasses: The twins during their Last Stand.
  • Becoming the Mask: A slightly more literal case here.
  • Big Brother Mentor: Yaimao seems like the oldest or at least the most mature of the participants, and makes sure to keep an eye out for Sorincha and protect Hikkora, who clearly looks up to him.
  • Break the Haughty: The most obnoxious player who acts all high and mighty? Reduced to a blubbering, terrified baby who actually faints in his final scene alive.
  • Cool Mask: The fox masks count, to some extent.
  • Creepy Child: A few of the players, including the Sorincha-imposter, and Hikkora at the end.
  • Creepy Twins: Subverted. Despite their creepy silence and glowing eyes, they never do any evil at all.
  • Cute Mute: It's hard to say if she can really be called "cute," since her face is covered by a fox-mask, but the lone female player doesn't speak, and her mask/costume are pretty cute...Neither the muteness nor the cuteness lasts.
  • Demonic Possession: What the Fifth Demon is doing.
  • Dirty Coward: Noshiga, full stop.
  • Evil Is Not Well Lit: In the city, the darkness is a constant backdrop to the events that take place. Of course, light isn't exactly any better...
  • Evil Sounds Deep: The reason why the girl doesn't speak until the end of the game.
  • Exact Words: Yaimao told Hikkora to find Sorincha. Hoo Boy.
  • Ghost City: Where the game takes place.
  • Glowing Eyes of Doom: Subverted with the twins. Played straight with the demons.
  • Hunting the Most Dangerous Game
  • Ironic Nursery Tune: Well, it's not a nursery rhyme, but it's said in a creepy sing-song voice.
    "Reeeaady or noooot...Here I come."
    • And right before poor Yaimao is skewered!
    “Who will play hide and seek with me?”
  • Kill 'em All: Or rather, kill all but Hikkora. He just gets possessed by the main demon - arguably a Fate Worse Than Death.
  • Last Stand: The twins make one against the demon pursuing them, choosing to go down fighting when they're cornered.
  • Living Battery: The machines use the children they captured for this.
  • Mecha: The demons's designs are partly based on this.
  • Oh Crap!: When Hikkora realizes that Sorincha is the fifth demon.
  • Ominous Fog: Appears at the end.
  • Parental Abandonment: Seriously, do any of the kids' parents know where their kids are going, what they're doing? Do they even have parents?
  • Powered by a Forsaken Child: What happens to the children who play the game and lose? Their bodies are taken to the center of the town and are plugged into strange machines—their Life Energy is used to light up the town.
  • Red Eyes, Take Warning: Subverted with the twins. Played straight with the demons.
  • Scenery Porn: To the point where the other wiki's article postulates that the theme of the work has something to do with the urbanization of Tokyo.
  • Schmuck Bait: The Nine-Tailed Fox tells the children exactly how to reach the arena and specifically of the demons to pique their interests. The kids naturally don't listen.
  • Senseless Sacrifice: Yaimao attempts to buy time for Hikkora near the end as they flee. Senseless in that Hikkora then chooses not to run.
  • Sibling Team: The twins, plus Sorincha and Hikkora kinda.
  • The Speechless: It's left unknown whether the twins can actually speak at all.
  • There Are No Adults: No adults are seen or even referred to in this short—no, no one even mentions having parents. (Early concept art shows that originally, there were going to be adults in the town, but any adult who came in to find their children was turned into a featureless, mindless zombie.)
  • Too Dumb to Live: All the kids but especially Noshiga for not listening when Sorincha the Big Bad tells them explicitly about all the dangers that they promptly disregard as fairy tales until its too late.
  • Vicious Cycle: The losing children are used to light up the city. The light is used to attract new children to the town to play the game.
    • The "winner" - basically, the last one standing - is possessed by the final demon, is made "it", and is used to lure in more children, as we see with Hikkora in the end. Not to mention, and on a side note, the same thing probably happened to Sorincha earlier (off-screen) before "she" passes her brother the baton figuratively speaking, as it is highly likely that she was the previous "winner"; and that would explain why Hikkora thinks he is seeing and hearing his sister at first even though she is not the same anymore since the Fifth Demon has taken over her.
  • Voice of the Legion: What the Fifth sounds like.
  • Youkai: The demons' designs are based on traditional youkai, for instance the Fifth is meant to be a Kitsune.
