Ukimiya was a weekly-format murdergame set in an abandoned Japanese castle. Thirty Warriors have been summoned from their homes to help combat The Corruption, a mysterious force tainting the world - the catch being that only nine are needed, and the rest must be weeded out through a Deadly Game.
It can be read on Dreamwidth, and was concluded in 2017.
Ukimiya provides examples of:
- Amateur Sleuth: The only detectives in the game are Misora and Mako, so everyone else is forced to act as one.
- Color Motif: Nearly everything in the castle (and on a meta level, the information pages) is themed with an unpleasant shade of green.
- The Corruption: Why the Warriors were kidnapped in the first place. Moreover, The Sage himself was influenced by the corruption for the duration of the game. Once it's cleansed, he's perfectly personable.
- Disc-One Final Boss: The Sage is the main antagonist for the majority of the game, but at the final trial, he's disposed of pretty quickly.
- Does Not Like Guns: Having come from the end of Minagoroshi-hen, Hanyuu just witnessed all of her friends getting shot to death, so she doesn't take Mahiro waving his gun around very well.
- Do Not Go Gentle: Both Tiki and Misora fight back against their killers before their respective demises.
- Ending Memorial Service: Each trial is followed by an "afterparty," of the survivors catching their breath.
- The End... Or Is It?: By the end, Rika and The Sage find a mysterious scroll near the pond, but it promptly bursts into flames.
- Exact Words: "The World" is listed as one of his favorite things on The Teishu's profile. Turns out that's the name of a terrarium he owns.
- Hope Spot: Rika Furude escapes from her killer and makes it to Hanyuu's room - but dies right outside the door as the walls are soundproof and so her cries for help are in vain.
- Lethal Chef: Senhime's cooking is pretty terrible. Taken literally when she kills Hei with a poisoned cake.
- MacGuffin: The titular dragon balls turn out to be the key to cleansing the corruption and bringing back the dead.
- The Mole: Koichi Kizakura is the mole for the Sage, though he only cooperates because Kyouko Kirigiri, his best friend's daughter, is being threatened.
- My God, What Have I Done?: The Sage is horrified by his actions once he's no longer corrupted.
- The Nicknamer: Tiki gives everyone in the game a nickname, whether they want one or not.
- Not Just a Tournament: The Sage explains that everyone has been brought to the castle to weed out the nine most worthy Warriors. When nine are left, he reveals he never intended for them to survive past cleansing The Corruption in the first place.
- Not Me This Time: Sen tries to frame The Joker for the week 2 case, but he doesn't even show up on the suspect list. Averted when he actually is the culprit on week 4.
- Off with His Head!: The Teishu decapitates Mahiro Fuwa for trespassing.
- Reformed, but Rejected: Once the corruption is cleared from his being, The Sage (who is really The Saniwa) tries to apologize to the players for putting them through the game. Many of them don't care and decide to beat him up instead.
- Sacrificial Lamb: Echoing her repeated deaths in canon, Rika Furude is the first in the game to die.
- Sealed Evil in a Can: The Teishu was sealed in one of these pre-game. Hegets re-sealed into a ramune bottle at the final trial.
- Shapeshifter Mode Lock: Hanyuu is locked into her adult form for the duration of the game, rather than the disguise of a 12-year-old that she uses in Higurashi proper.
- Time Abyss: The age given on The Teishu's (Zamasu profile is 25,000,000.
- Trail of Blood: Quite frequently one of the pieces of evidence during a trial.
- The Unseen: The Emperor Ambassador Laquatas is only ever seen by the dead characters, everyone else he communicates with via writing.
- You Didn't Ask: The culprit of the second week says this in response to why they didn't confess earlier on. Every week after that, the trials start out with someone asking the suspects if they committed the murder just to avoid this scenario.
