I’m drawn to its grand sense of scale and refined sound.

“MONTAGE” was released in May 2025 and was chosen as the opening theme for the TV anime “The After-Dinner Mysteries.” The composition is by Hiroyuki Sawano, known for works like “Attack on Titan” and “Mobile Suit Gundam.” The fusion of a mysterious atmosphere with a danceable rhythm is striking, and Kento Nakajima’s expressively rich vocals are another highlight.

The thrilling melody that echoes the anime’s story is superb as well.

Be sure to listen closely and immerse yourself in its world.
