Coin

Coins are a type of common weapon. As the name suggests, "coins" are about the size and shape of a quarter. Most coins glow blue when active and turn gray when they are "released". Coins have a wide range of functions. Some coins are more powerful than others.

History
Coin technology was advanced largely thanks to Jinsei's father, the former emperor. They are "artificial" and use energy extracted from Spirit Coins. As a result, normal (blue) coins are not as powerful as Spirit Coins (red). Jinsei also states that the empire "wanted to see the limits of these artificial coins", which led to the development of Regalias.

Use
Coins are inserted into slots on a person's gloves (androids can also use coins). Tapping activates a deactivated coin, and deactivates an activated coin. They can be switched in and out and can be stored in tubes/capsules. Coins can be bought from vendors.

According to Flayvus, most people can only use 2-3 coins. Jinsei, however, can use 4.

Coins can also be used to power androids such as Nine.
