Chiru
Chiru (チル) is the money used in the Denjuu World. Chiru literally means "to scatter".
In Telefang 1, the amount of Chiru you get for winning a battle is 8 times the opponent's level. If one fights against a T-Fanger that has more than 1 Denjuu, then only the first Denjuu that the T-Fanger uses will be factored in.
In Telefang 1, the maximum amount of Chiru one can hold is 65,000. This is close to the 16-bit maximum of 65,536. In Telefang 2, the maximum is a much higher 9,999,999.
In Telefang 1, if one loses against a wild Denjuu, or the first boss fight against Golaking (which is inevitable), then half of their Chiru will be gone.
In Telefang 1, running through grass can reveal coins, which are worth 5 Chiru, and diamonds, which are worth 80. Diamonds found from breaking vases are not worth any Chiru. In Tehefang 2, coins can also be found by running through grass; each coin gives a variable amount of Chiru.
