First revealed in Dengeki Playstation Magazine, the first batch of Sega Hard Girls have been confirmed for Hyperdimension War Neptunia VS Sega Hard Girls: Dream Fusion Special.
- Dreamcast (CV: MAO) possesses a fairly straightforward personality filled with a strong sense of justice. She gets along with everyone easily and cares for her relations with people. Her facial expressions change often and change drastically; it's simple to tell what Dreamcast is thinking about at any given time.
- Sega Saturn (CV: Minami Takahashi) is a serious girl who likes to act tough, but she often gets embarrassed when someone praises her. Unfortunately, she tends to get a bit weak when sudden emergencies pop up.
- Known for her extensive knowledge base, Mega Drive (CV: Shiori Izawa) is a respected honors student who carefully analyzes her surroundings constantly though she's a bit clumsy about certain things. While she's usually stoic, Mega Drive actually longs to be more ladylike deep inside.
- Game Gear (CV: Minami Tanaka) bears a more reserved personality who prefers being indoors and gets fatigued easily. Her pessimism does not make her a good match around others.
Four additional characters from the Hyperdimension Neptunia series also hop aboard the madness.
- Neptune (CV: Rie Tanaka) is now a motorcycle! The main heroine from the Neptunia series has fallen victim to the history-altering shenanigans brought forth in the game and has lost her body after the intro battle with Sega Saturn due to an unknown reason.
- With her older sister in peril, Nepgear (CV: Yui Horie) joins in to save Neptune. She has the same personality from the other Neptunia entries and remains easy to push around.
- Plutia (CV: Kana Hanazawa) from Hyperdimension Neptunia Victory is still the adorable, air-headed girl that receives a stark personality shift when she transforms. She repeatedly wants to take abrupt naps through the adventure no matter where the party is.
- Meanwhile, Uzume Tennouboshi (CV: Mariko Honda) from Hyperdimension Neptunia Victory II leaps into the fray with her burning sense of justice. A skilled fighter who often likes to convey her feelings with fists first rather than words though she does make girly gestures at times.
Hyperdimension War Neptunia VS Sega Hard Girls: Dream Fusion Special will be coming out for the Playstation Vita, but no release date has been shared yet.
