Y-Zetta

The Y-Zetta, or Yliaster Zetta is an advanced version of the Y-Nano manufactured in Tenryūji. It shares similar functionality and overall usage, although it has a much larger core system, and hence can manipulate far more cubes. Yūmei keeps it contained within the Hokage Residence to monitor the entirety of the city, as well as its surroundings which grants him a morbid form of omniscience when used in conjunction with the Telescope Technique.

As it has the ability to download apps, the sheer volume of cubes can completely overwhelm unsuspecting foes within a short span of time.
