K-Square
The K-Square is an obsolete K-Storage format.
Functionality
K-Squares work on the same principle as modern K-Storage devices, using a tractor beam to lock onto a recipient Kreature's nucleus, converting it into pure concentrated aura. Due to the technological limitations of the era they were invented, K-Squares instead store Kreatures on special discs made from of ground-up K-Gems. Tamers could use the touchscreen on the front of the Square to identify the Kreature inside and check its vital statics. Additional buttons below the screen can beam the Kreature in and out of the device and turn it on or off.
In more recent times, K-Storage technology has become much more powerful and efficient and production costs have decreased, allowing the functionality of the K-Square to be added to Tamer Amulets. However, this did not entirely spell the end of the K-Square. Some Tamers enjoy their retro appeal and make use of them as a fashion statement, and a dedicated subculture has formed around the collecting and trading of vintage K-Square models.
