To write a good Vocaloid Miku x Kaito fanfic, you need to have a good grasp of their relationship dynamics. Are they just friends, or is there a romantic undertone? Build on that. Create conflict. Maybe Miku wants to pursue a different music style than Kaito, and they have to work through their differences. And don't forget about the setting. It could be a virtual Vocaloid concert hall or a dreamy landscape. Make it immersive for the readers.

Kaito could also feel indebted to Shinichi if he was in the process of protecting Kaito when he got shot, leading to a closer bond between them.
