Yen is the main currency used in Demonfall. Yen becomes limited after beating Final Selection and requires some work put in to get more. Yen is obtained by killing Demons, selling Trinkets, selling Demon Parts at the Slayer Corps HQ, doing quests, trading, selling broken nichirin at the Demon Hideout, and more in the future. You drop Yen by clicking the coin icon as seen in the picture. Another bar will appear where you type the amount of Yen that you want to drop, then click drop.
On the Bottom left of your screen, you will be able to see your yen(and also drop it).
Yen can be used for the following:
- Fast travelling (Talk to the man with the horse-pulled wagon, found in the three main villages and costs 100 yen per travel), or go to the man sitting around a campfire at Slayer Corps HQ or the Entertainment District to teleport.
- Buying Unique outfits.
- Paying Breathing Trainers (Money needed for Thunder Breathing, Mist Breathing, Water Breathing, Insect Breathing, Love Breathing, Serpent Breathing and Stone Breathing).
- Buying food
- Buying items from the Black Merchant.
- Trading for other items.
- Forging Items (e.g. Nichirin Swords, Crystal Key, Sawed-Off Shotgun...etc).
There is a little trick, where if you go to Kamakura Village, there will be a couple next to the soup store. If you talk to the man, he will give you 100 yen for free. This can only happen once, but it's nice to know if you ever go there and want some extra yen.
WARNING: When you get executed, you lose 25% of your yen. Leaving while a skull symbol has appeared will also.
