Ryo is the game currency of TheNinja-RPG.
From the item shop, you can buy armor, weapons, and various items with different purposes, including food and soldier pills to recover HP in battle.
The ramen shop is the easiest way for a villager to recover their own HP. Using ryo, you can buy ramen of various sizes from the ramen shop. The bigger the ramen order, the more HP you'll recover.
When you lose a battle, you are hospitalized. When this happens you must either wait 15 minutes for your body to recover, or bribe the doctors to heal you immediately. You can bribe the doctors using ryo. The higher your maximum HP is, the more expensive your hospital bill will be.
All jutsu except forbidden jutsu require ryo to train at every level. The costs also go up every level!
You can also use ryo to undergo surgery, which will drastically increase your maximum HP. The higher your maximum HP is, the more expensive your surgery bill will be.
Ryō (Japanese coin), a gold piece in pre-Meiji era Japan worth about sixty monme or four kan
