Today, Idea Factory International updated the character information on the Hyperdimension Neptunia Re;Birth2 official site. The information is about the Oracles of each land: Histy, Chika, Mina, and Kei. I personally recommend checking out the description given for Chika; it’s pure gold (Vert certainly has her hands full). It should be noted that this will be the first time in the series some of these characters will be involved in combat as well.
You can check out the updates on the official site, and keep it here for all the latest information on the release.
