The word "Maple" can be spelled when putting together the first letters of five of the six main Hero characters: Mercedes, Aran, Phantom, Luminous, and Evan. Shade, the sixth character, is intentionally not included because his existence was canonically long forgotten when the Black Mage was sealed away before the start of the series.

However, Evan did not exist at the time the Black Mage was sealed. Evan's deceased predecessor, Freud, was one of the six Heroes who sealed the entity. Considering this, Shade could still be included to spell "Maple" by way of his original name "EunWol" ("은월") used outside of the North American/European/Oceanian servers for the game, while Freud would still act as the class to leave out.

Additionally, in the Explorer characters' plotline, the NPC characters that accompany the player character are named Sugar, Tess, Olive, and Rondo. If the player character is designated as "You", their first letters spell the word "Story".
