The games that inspired us, and the developer’s story →
First, the prosecutor turns his theory of the case into a song. The lyrics are the prosecution’s version of events, so somewhere in them there’s a contradiction. Kanade, who has lost her memory, is stunned: “S-sing?! Here?!” But in this country’s courts, that’s simply how it works.
Now it’s Kanade’s turn. She reworks the prosecutor’s lyrics with her own deduction and sings the truth as a musical. Even if music games aren’t your thing, you’ll be fine.
There are no rhythm-game button presses.
Expose a contradiction in cross-examination and refute him, and the prosecutor concedes: “...Ngh. ...The prosecution withdraws line seven.” Every line he withdraws gets a red line struck through it.
During a break in the trial, go with your gut and name the culprit. You can also skip it and play on. If you guessed right, you can look back on it on your Defense Score.
This doesn’t affect the story or the mystery.
Casual, Normal and Hard. New to mysteries? Enjoy the story on Casual. Play mysteries now and then? Go with Normal. Love mysteries? Take on Hard, where you can’t use hints and there are more blanks to fill.
Your difficulty is recorded on your Defense Score.
An extra mode for anyone who wants to sing the musical, and something to come back to. Sing along as the lyrics change color. With a microphone, you can get a score too (whether this works depends on your setup). Wait, you want to take it on blind, first time through? Bold! Of course you can!
You can play to the end without singing.

The heroine. She comes to at the sound of a gavel, sitting at the defense bench, unable to remember even her own name.
Kanade’s senior, in the next seat. He has noticed she has no memory, and quietly covers for her in court.
It’s his first trial, and he does everything strictly by the book.
An upbeat streamer who holds the speedrun record for the hit game Night Lantern. “Let’s speedrun a not-guilty today!”
Easily moved to tears. He keeps a keychain from his grandson hanging inside his robe.
Kanade comes to at the sound of a gavel, and finds herself at the defense bench of a courtroom. The rookie defense attorney can’t remember anything, not even her own name. Shigure, her senior in the next seat, has already noticed, and murmurs: “You’d better not say that here. An attorney with no memory gets removed from the case right away.”
The defendant is Tsubame, a streamer who holds the speedrun record for the hit game Night Lantern. “Let’s speedrun a not-guilty today!” she calls, waving from the defendant’s seat.
The case goes back two months, to the game festival Neo Candela. In the demo room of a studio’s booth, the famous director behind that game was found dead. The murder weapon, a trophy, bears only Tsubame’s fingerprints. Earlier that day, on stage, the director had laughed at her and called her a “liar.”
And in the dead man’s hand was an old handheld console. On its screen, the ending kept on playing.
Across the courtroom sits Haneda, a prosecutor in his very first trial. The prosecution’s theory, they say, will be presented in song.

The planning and game design of this game were done by the developer, and generative AI was used in its production. Generative AI was used for the character, background and evidence art, the music, songs and shouts, and the translation. The script, dialogue and program were selected, expanded and revised by the developer from multiple AI drafts. In every case, the developer chose the content, fixed what needed fixing, and checked the rights to the assets before adding it to the game.
