The Anime Lad
After creatures called D2 emerge from a meteorite and begin hunting sound, performed music becomes dangerous. Musicarts answer by drawing power from classical works to fight them. Concert etiquette has changed considerably across the frightened world, although arriving after the monsters remains as undesirable as ever.
Super Eyepatch Fox
Monsters called D2 emerge from a meteorite and react to music. Melodies become taboo. Girls called Musicarts draw power from classical works and fight back, turning the old repertoire into bright combat language. Every performance risks attracting an audience built entirely for destruction again and again.
Gigguku
The premise makes music dangerous, then gives classical works explosive combat energy! Musicarts fight the D2 through the power of famous scores, so the action can move with a performance pulse. It is a huge visual answer to a world that has been forced into silence.
Father's Basement
The terminology arrives polished before the underlying rules feel solid. Still, making music both forbidden and useful in battle is an effective contradiction. The D2 threaten anyone who plays a melody, while Musicarts draw power from the same cultural history the world has been forced to suppress.
