- "We cannot afford to have Eblan's traditional ninja arts fade away into history, Master."
- —Gekkou to Edge
The Eblan Four (エブラーナ四人衆, Eburāna Yonhitoshū?) are disciples of Edge Geraldine in Final Fantasy IV: The After Years. The group consists of Gekkou of Fire, Izayoi of Water, Tsukinowa of Wind, and Zangetsu of Thunder.
Each of the Eblan Four has different stat growths and Ninjutsu skills. Gekkou emphasizes HP and Strength, Izayoi has high Spirit, Tsukinowa has high Speed, and Zangetsu has high Intelligence. Gekkou learns Fire-elemental Ninjutsu, Izayoi learns Water and Ice-elemental Ninjutsu along with healing abilities, Tsukinowa learns Wind-elemental and defensive Ninjutsu, and Zangetsu learns Thunder-elemental Ninjutsu.
They also have different equipment draws, with Gekkou using hammers and axes, Izayoi using bows and whips, Tsukinowa using boomerangs and Zangetsu using spears. Compared to Edge they each focus on specific strengths, while Edge is better rounded learning a larger variety of Ninjutsu skills and having more balanced stat growth.
Gekkou and Zangetsu appear briefly in Final Fantasy IV -Interlude- just before Edge departs for the Cave of Eblan, where they agree to stay behind and guard the castle in his absence.
The Eblan Four are the focus of Edge's Tale in the game, each being sent out to gather reconnaissance about other regions of the world before returning to Edge. They are among the handful of characters in the game who can be permanently lost - if any of them perish in their part of Edge's Tale they cannot be used later in the game when all the party members assemble.
If the player successfully completes their quests, they will rejoin Edge in the final part of the tale and accompany him until the end. Gekkou has the unique ability to be lost if the player chooses to challenge the Mysterious Girl when he meets her, as she will instantly cast Meteor and kill him. To avoid this the player must choose not to confront her.
Each of the Eblan Four has one Band ability to be used by combining with one of the other members. The four together can use the "Wheel of Elements" Band, and with Edge can perform the five-way Band "Ultimate Art: Advent of Phoenix". Due to their time undercover in the regions of the world they can Band with characters from those regions. Gekkou can Band with Yang, Izayoi can Band with Leonora, Tsukinowa can Band with Palom, Porom and Ceodore, and Zangetsu can Band with Luca. As the female of the group Izayoi can also partake in Bands involving the female party members of the game.
