Disgaea 5 bringing back all the Disgaea 1 feels

I've been playing Disgaea 5, and I'm really enjoying it, but I don't think this would be nearly as fun if I hadn't played Disgaea 1. A certain minor character from 1 is in 5 and it's one of the few times where giving a detailed backstory of a side character actually makes the original game a lot more interesting. Disgaea 1 was already solid, but still.

Did Vyers fuck the prinny?
