Trivia / Disgaea 4: A Promise Unforgotten

• Feelies: The US Premium Edition comes with an artbook, a OST, and a Fuka figurine. The Super Premium comes with all that and an additional 9 figurines.
• The Other Darrin: Prier and Zetta, switching from Richard Epcar to Patrick Seitz. In the Netherbattle Tournament, Asagi^note Asagi's original voice actor provides her voice in the Post Game and the new battle dialogue for HD Asagi's DLC releases uses her original voice actor. Impressively, the rest of the returning characters retain their original voice actors.
  • How much Asagi falls under this trope is debatable. Her Japanese voice actress changes every game, which is mocked by Prinny 2's ads for Asagi Wars (She even comments in that game she "Has the same voice for the first time").
  • Sadly, Troy Baker did not return as Valvatorez for the Vita-exclusive content. Instead, he is replaced by Matthew Mercer ^note This is mostly because Troy Baker is a union-only member now and the Disgaea games are non-union, although it should be noted that Matthew Mercer and Troy Baker's vocal ranges are very similar. Also a Hilarious in Hindsight since Matthew Mercer also took over Troy Baker's role as Kanji..
