るばんがー！って何？

あど雰囲気になるかもなプロンプト（ベルバードさん提供）（厳密にはこちらの利用らしい）

Dark, high-intensity J-pop fused with rock and electronic elements, shifting between aggressive and emotional passages at a dynamic tempo around 120–150 BPM.
Expressive female vocal with wide range, dramatic tone shifts, moving from soft, controlled phrases to powerful, explosive belts with sharp articulation.
Heavy beats, distorted accents, and layered synths combine with rock instrumentation to create a tense, cinematic atmosphere.
Song structure emphasizes contrast, with unpredictable transitions, tension-building verses, and impactful, hook-driven choruses.
Polished, high-definition production with bold dynamics, deep low-end, and crisp vocal presence at the forefront.
Avoid flat, monotonous delivery or overly gentle arrangements that reduce emotional impact.
