Remilia's cake has vanished from a locked room in the Scarlet Devil Mansion! With the help of head maid Sakuya, play Russian roulette with a 12-gauge shotgun and punish the suspects. Good luck!

Welcome to a late-night tea party hosted by head maid Sakuya. On the table sit tea, cake, and — a single shotgun.
A single shotgun is loaded with a random mix of blanks and live rounds. At the start of each round the NUMBER of shells is revealed, but their ORDER stays hidden. You'll have to rely on luck, memory, and reading your opponent to pull the trigger.

Of course, items are there to help you — handed out at random each round. Sakuya lifts the silver cloche to reveal them, and carries out every effect herself, with the utmost elegance.

Koakuma → Hong Meiling → Patchouli → and the boss, Flandre. Face the residents of the Scarlet Devil Mansion one by one in a tournament, and survive to the end to find the cake thief.
