What are Onikami codes used for?

Onikami codes are especially valuable because they can reward Sun Essence, one of the game’s most valuable resources. Sun Essence allows Demon players to gain immunity to sunlight, removing a big survival restriction, and is also required to unlock Sun Breathing, one of the strongest techniques available. Since this item is normally locked behind high-level bosses or rare drops, getting it through codes can save a huge amount of time.
