If one were to point out the most popular style of Vocaloid, it would be a structure that completes a single narrative within a single song. Since this structure has certain limitations when it comes to weaving an entire album into a single story, major Vocaloid artists often abandon album-level storytelling and focus solely on sonic cohesion. However, KurageP brilliantly pulls off album-level storytelling while maintaining this style. As much as I would love to explain the process step by step, it could be a spoiler, so I recommend listening to the album yourself to check out the details. (I think watching the MVs while listening to the album will help you understand the story.)
