The rapper/producer Deko has been doing some very interesting stuff with adding vocaloid synth characters to rap/hyperpop music. He has two vocaloid "characters", Lil Yammeii and Lil Hard Drive. Most vocaloid rap I listen to is terrible but this stuff is super well produced. He'll even do things like add breathing noises to the vocaloid tracks, which improves the sound a lot. https://youtu.be/usRDtHjYKzU

He also has some funny parodical bits he does, like rapping about having a lot of money/jewels/etc and then the vocaloid characters rap about having a lot of RAM.
