I just recently finished SSSS.Dynazenon which I really loved. I did notice that there were some voice dramas that added to the story. This is one of the stories that the audio is nowhere on youtube so I thought why not! We never see Gauma and Mujina properly interact in the anime which is why I really like this voice drama.
