C.C.V

C.C.V (電流割り出す目庇, Denryū Waridasu Mabisashi; lit. "Current Computing Visor") is a mechanical visor that was engineered by Shin Inari when he was only ten years old.

Overview
The C.C.V uses a small computing device and micro-circuitry and has an external storage database; that when inserted via another microchip allows it to cross reference the resistance and voltage of items and has a computerized ammeter that could calculate the current flowing through a certain material, when used in combat, it would allow him to also calculate the time it would take for the current to reach him and predict the path of certain electrical attacks. This calculation was done in real time but at an accelerated speed. However, the visor would often face heating issues and the circuit would often melt or breakdown. Also, the monitor used for the visor was made of glass and not polycarbonate lenses; making it prone to smudges and cracks.
