Happy to hear you found DD's other stuff.
So far i can tell it is not yet a focus of us to add specific Anime references, they might very well happen by sheer accident or active will in the future but that is something that we all will have to see.
I'm certain there is gonna be atleast some in the future, though you should not bet on my Word on that one.
Still, Happy to see that you are satisfied so far with the Game, DD and the Team try their best to deliver.
