11th December 2025: We added new Lost Sword codes.

Lost Sword is an epic anime fantasy role-playing game where you spend your time building up your characters into powerful warriors while also getting to know them as people and developing your town.

Between battles and story developments, you can spend Diamonds on Summons, which grant you new characters and pets to send into fights. Like any gacha game, building up your collection of characters is part of the fun, especially in a game with as much emphasis on character interactions as Lost Sword.

Earning Diamonds and Summons, especially as you leave the early game, can be quite the grind, but that’s where Lost Sword codes come in handy. Lost Sword codes provide all manner of freebies and useful currencies that can be spent on new Summons or upgrading characters, so make sure not to miss out on them!

Here are all of the Lost Sword codes we've found and how to redeem them.
