モーツァルトの魔法の笛 / Mōtsaruto no mahō no fue (Tankobon Softcover)

The flute feels like such a charming and unique magic object. I'm curious if it was inspired by any traditional folklore or personal fascination.

The book had a warm, light tone that made the magic feel accessible and fun. Were you all drawn to the same sense of whimsy and friendship?

The detailed descriptions made the fantasy world feel vivid, but I wonder if there was a detailed outline or if it evolved during writing.
