Famitsu published an article disclosing the initial wave of DLC to be made available alongside Etrian Odyssey V: The End of the Long Myth when it launches in Japan on August 4th. To begin with, five different character skin options will be available, at 300 yen each. These are: the “School Uniformed Boy”, “Sailor Uniformed Girl”, “Sweater Wearing Girl”, “Etrian Odyssey 1 Paladin New Illustration”, and “Etrian Odyssey 1 Medic New Illustration.”
Besides character options, there are also extra quests to check out. Both priced at 300 yen, Adventurer Training Plan yields an accessory that triples experience points per battle, while the Adventurer Good Luck Plan yields an accessory that boosts the yield rate to 100% for materials that don’t have drop conditions (kill by Petrification, by Ice, in one turn, etc.) from enemies.
You’ve probably seen our article about the FM soundtrack option. Priced at 800 yen, this item and a sixth Etrian Odyssey character skin (or pack?) option will be dated and detailed at a later time.

By the way, the Famitsu article linked for this writeup mentions that the July 28th issue of Weekly Famitsu will contain a special Yuzo Koshiro (composer for many games, and the Etrian Odyssey titles) interview and a “Aeolian Coloring Book” themed by Etrian Odyssey V.
