FD

Gymnos's FD has increased in response to a phone question in Telefang 2

FD is a measure of how friendly a Denjuu is, on a scale of 0-100. The higher a Denjuu's FD, the less likely they will be to display bad personality traits. FD can be raised by talking to the Denjuu often, answering questions for them over the phone, and giving them gifts.

FD can be lowered by losing battles, running away from battles, or answering phone questions incorrectly.

Name Etymology

"FD" is described as being short for "friendship do" (Japanese: 親密度, shinmitsu do), meaning friendship points. The acronym is jokingly referred to as standing for "friend doints" in English.

FD Bug

In Telefang 1, it is possible to raise FD to numbers over 100 by answering a Denjuu's questions correctly over the phone. When this occurs, the calculation for how the Denjuu behaves according to its personality overflows, leading to the Denjuu misbehaving far more often than if it had 0 FD.
