Gekkou is the stalwart leader of the Eblan Four in Final Fantasy IV: The After Years, also known as Gekkou of Fire. He is a warmhearted, honorable man of few words.
Gekkou is a muscular ninja, wearing a red scarf with a black garb under it. He wears a steel band around his head and goes barefoot.
Gekkou is loyal to Edge, especially his advice to survive, no matter what happens. He agrees with the Mysterious Girl, because her philosophy agrees with Edge's advice. She claims that honor is not something to die for just to get revenge, making Gekkou value his life more than giving it up after seeing Fabulian monks die to avenge their dead brothers killed by her.
