Muramasa: The Demon Blade was the first game from Vanillaware and Marvelous. The two companies are working together again on Grand Knights History.

Yoshifumi Hashimoto, producer on Muramasa, is also the producer on Grand Knights History. This upcoming title is an original RPG and its in development for PSP. Since Princess Crown was a port, Grand Knights History will be the first time Vanillaware created a game for Sony’s handheld.

Grand Knights History is slated for release this summer in Japan.

Update: The stage is set in Grand Knights History for three kingdoms to fight over for control of Ristya. Famitsu’s scan shows King Fausel is the ruler of Logres. Queen Muse is the leader of Avalon. King Leon and another character control the other land cut off by the scan. You are a knight in the army. Before the story begins you get to design your own character. Players can choose a gender, what their knight looks like, and voice acting.

Grand Knights History uses a turn based battle system with royal rules in the mix. A sliver of the scan shows this PSP game has some kind of network support, but the details are also cut off.

Update 2: The third kingdom is Union and is governed by King Leon and Princess Sefia. Gender may play a role in what types of equipment characters can exist. Pictures show male characters armed with two handed swords and a gun-like weapon. Female characters are magician types or priest-like characters with a hammer.

As mentioned before, the battle system is turn based. Similar to many 16-bit RPGs, heroes are on the right side of the screen and enemies are on the left. In the top left you can see meters for HP and AP. Characters can move around on the battlefield too. Grand Knights History will be Vanillaware’s first turn based game. Tomohiko Deguchi, Director, says Grand Knights History is an "everyone is tied to war RPG." Players are connected to each other offline and online through a network mode. This isn’t the kind of game where you team with friends when playing solo. You fight other players in battle. It seems that all players are locked into the war for Ristya and are fighting for one of the three sides.
