Floors[]
| Floor | Start/failure flavor texts |
|---|---|
| Ⅰ Mist-stricken Missteps |
17:03 There is fog covering the entire area, and our squad has lost our way. Are we pushing forward, or are we merely dissolving ourselves away? The mist has completely overwhelmed you. There is no longer a need to seek a way out, for this has become your home. |
| Ⅱ Sunset Courtyard |
19:24 The courtyard is filled with the sunset's afterglow, yet that is not the color of hope. Come in, come in, esteemed guests who have wandered astray. The castle welcomes you. The castle has numerous trials in store for its visitors, and you are unable to pay the price of failure. |
| Ⅲ Homeland Remnants |
20:36 As the mist spreads into the castle and the vines make their way up the columns, the dark night appears to have retreated elsewhere for the moment. Do remember as you enjoy this moment of respite, however, that darkness is always right around the corner. As you succumb to the dark shadows, you too will become part of the history of this place. |
| Ⅳ Nightmare's Prelude |
21:53 Darkness falls, the candles throughout the deserted castle begin to light up by themselves, and the silent Nightzmora begins to roam the shadows in search for prey who have lost their way. The candle flames flicker ceaselessly, just as you yet remain in this old castle. You surrender to your endless nightmares, never to awaken again. |
| Ⅴ Blood-soaked Corridor |
00:00 Blood moons often signify the beginning of unfortunate tragedies in written accounts, and this omen is now shining down upon us through the windowpanes that line the corridor. What will emerge beneath the blood moon? Panic? Fear? Frantic wailing? So be it. You have experienced it all. |
| Ⅵ Hall of Desires |
--:-- The purest and truest desires, standing above all time, have engulfed this space whole. Here, there is nothing but the endless thirst for aesthetics, fine arts, and perfection. Too bad. You are not entirely unblemished. |
Additional information
The 6th floor is only accessible by clearing the 5th floor while having either  Abrupt Realization or  Act 1. | |

Result[]
An example of Phantom & Crimson Solitaire run's result screen; this one is completed with the Crimson Finale ending. Due to lack of space, only Operators that had been recruited are shown here.
When a Crimson Solitaire run ends, the ending will be shown if the run is completed; if the run fails, the "Reverberation" message is shown instead.
Afterwards, the credits (which can be skipped and viewed again from the result screen) will roll, showing the player's nickname under the title "Blood Diamond" and the Operators they have recruited throughout the run as the "casts", and highlights the player's actions throughout the run.
