Three new Summon Night 4 characters have been introduced. These three will function as the de facto guardians of the dragonets. The dragonet that the player chooses at the beginning of the game determines which of these three characters will become the main character.

Liviel, an apprentice angel, is very intelligent and knowledgeable — valuable characteristics in someone training to become an Angel of Knowledge. She was appointed to become the governess of a dragonet. Aloerie, a winged warrior from the beast lands, trained hard in the mountains to earn a role as a dragonet's guardian. She has great confidence in her skills with a bow. Lastly, Seilon is a half-dragon, half-human from the demon realms. He comes from a prestigious family and maintains a dignified personality as he carries out his orders as a dragonet's guardian.

Summon Night 4 will be released in Japan on November 30th. No North American release has yet been announced.
