The Drummer’s Last Ten Days: Shiina Taki's Decameron is an interactive novel based on the original anime BanG Dream! It's MyGO!!!!!, with the drummer Shiina Taki as the protagonist.

Over the course of 6–7 hours of gameplay, players will experience the story from Taki’s perspective, set seven years after the events of the anime. You’ll encounter a mix of familiar and unfamiliar characters.

The game features multiple endings, with character routes that are interconnected, interactive, and even include some randomness. Certain choices can have far-reaching consequences.
