Digivice

Digivice
A digivice is the name for the device granted to humans that connect them from the Human World through to the Digital World. The exact machinations of this connection depend on the model, but all digivices grant access to the Digital World through Shibuya Train Terminal and Shibuya River.

D-Tector
The model of digivice granted to Spirit Users. Allows them to transform into the spirits they have collected on their travels.

(and yeah I forgot the names of the rest if anyone wants to add)
