Looking at the description, it seems that the UNI version is not a derivative, but a succeeding version. The video upload is by Xenesus, and the credits in the description says: Composition/Arrangement- Xenesus Lyrics - Xenesus, Rimyung Vocaloid- Uni Illustration/Video Editing - Rimyung Tuning - Xenesus, Yui

Looking at the about section, it seems that "Angelkist" is a group name, kindof like KEMU VOXX.
