Daikaijuu Monogatari

Daikaijuu Monogatari is a video game series of mostly Role Playing Games developed by BIRTHDAY, known for the game Lost Word Of Jenny. It features a fire elemental hero and three ally creatures called Shell Beasts, usually saving the world from evil. It utilizes a Dragon Quest-styled battle system on the games.

The original game was released in 1988 for the Nintendo Entertainment System as "Shell Beast Story". It was then published by Namco before BIRTHDAY decided to have a new publisher for their next hit game. The next game, basically called Daikaijuu Monogatari (or Greater Tale of Shell Monsters by a translator) for the SNES, was released in 1994 before Christmas and it sold millions of copies throughout Japan. As of that release, the series is published by Hudson Soft.

Birthday released a sequel called Daikaijuu Monogatari II for the SNES in late 1996, which have more detailed graphics, a time system, and much more. In the following year, a Trading Card Game called Daikaijuu Monogatari: Miracle of the Zone was available. There are two Game Boy games featuring this TCG. A manga based on the "MOZ" series is also released. A Spin-Off featuring one of the main Shell Beasts was released for the Game Boy Color.

The Daikaijuu Monogatari series is presumed dormant since the turn of the Millenium, although a mobile R Emake of the 1994 game was released in 2006. This series is one of the Dragon Quest clones out there, but one of the better ones. BIRTHDAY has been working on many properties in recent times, including the anime Fushigi Boshi no Futago Hime.
