Lucky Coins are an item exclusive to Okamiden. They can be used by Chibiterasu, in conjunction with Demon Parts, to upgrade his Weapons. The blacksmith in Yakushi Village will increase his inventory after Chibiterasu has supplied him with the requested amount of them. This means new upgrades will become available for crafting. However he will only set up shop after Chibiterasu has convinced at least one person to migrate to the village. Only five coins are needed to unlock all the upgrades although many more can be obtained. Giving a Lucky Coin to the Blacksmith will also net Chibiterasu some Praise.
 Lucky Coin Locations
- Save the injured crane near the entrance to Agata Forest. A woman in one of the houses will say she knew the crane he rescued and will tell Chibiterasu she has a present for him before running upstairs. If Chibiterasu disobeys her wishes and follows her upstairs before she is ready, she will turn into a crane and fly away. If he waits until she is ready, he will receive a Lucky Coin.
