The wrist communicator alerting Guy of a message.
The Wrist Communicator is a device held by Guy, capable of contacting others in the Girlchan in Paradise series. Not much is known about the device, although it can be said that it is very high tech, as characters such as Kenstar and Guy will marvel at the device when it receives a transmission.
There has only been one appearance of the Wrist Communicator in the series, in Episode 3. Guy receives a transmission informing the team that the twins have been kidnapped by Bushido Blaster #12.
