Sardine

Sardines are a reoccurring item in the Disgaea series. Valvatorez, first introduced in Disgaea 4: A Promise Unforgotten, eats sardines as a replacement for human blood after a promise he made to never drink human blood again. In game, he makes numerous comments about sardines, and his episode transition cutscenes involve him talking about sardines. It is assumed that he has a vast knowledge of sardines.

In Disgaea 4, it has been revealed that sardines are the favorite food of the Prinny group, and they will gladly work for it, for example, working around a whole day just for one sardine.

It appears in Disgaea 4 and Disgaea 5 as a consumable healing item, with strange descriptions such as "Ingredients consist of... one sardine."

A premium PlayStation Network avatar of a sardine was released alongside Disgaea 4 Complete+.
