"Two sleeping dragons -- one a sacred ally of mankind, the other its sworn destroyer. Two heroes marked with symbols of the dragons. Their meeting heralds the dragons' awakening -- and the world's ending."

Jump introduces the game's main character Krom, prince of the Kingdom of Iris. As Fire Emblem fans have speculated, he is of the Lord class and wields a weapon called Sealed Sword Falchion.

Krom is not the only main character, though. The game lets you create your own unit, freely selecting gender, face parts and other areas. This character serves as the game's other main character. The meeting between Krom and this character is a major part of the story.

Jump also introduces two gameplay components, Free Maps and the new Dual system. Free Maps are a returning feature from past Fire Emblem games. This system lets you freely move across the map and buy goods or take part in battle. The Dual system is triggered when you enter battle while next to an ally. You and the ally will enter battle together. In addition to your character gaining increased abilities, the ally character will help out with attacks of his own.
