C.A.D

C.A.D (奥伝勢揃い読み解く, Okuden Seizoroi Yomitoku; lit. "Cabalistic Array Decoder") is a magical-hand held, portable gizmo or gadget developed by Shin and allows him to use ultrasonic-frequencies to open locks, remotely disable and sabotage drones and destroy fragile objects. As demonstrated by a modified version of this device, it can intercept certain frequencies projected by communication lacrima's and cause interference in comm networks.

Overview
The Cabalistic Array Decoder is a miniature computer-like device created and used by Shin Inari that is a collapsible or rather foldable in nature; allowing him to carry it around in his pockets. It's a bright red machine that houses two distinct lacrimas; one of which is a typical "ultra-high yield lacrima" for the gadget to function, proving it with power, while the other is an element specific lacrima; sound, obviously used to produce adjustable ultrasonic frequencies. The device works by using using it's high end computing power achieved through a form of data-magic; which is very akin to Archive, to scan, compute and find out the natural resonant frequency of an object then by "tuning" into that certain frequency, ultrasonic waves are projected, resulting in resonance which causes drones to blow up, locks to be disabled/damaged beyond repair, glass to shatter, etc.

Since it makes use of ultrasonic waves instead of infrasonic sounds, it has shorter wavelengths and does not cause extensive damage to the human body, allowing Shin to use it as a form of non-lethal incapacitating weaponry. As ultrasounds are imperceivable to the human ear and thus undetectable, in Shin's own words, "they won't know what hit them". It can be used to temporarily paralyze or stun a human being; though, it could be used as a lethal weapon when used against the likes of Vampires and Lycan's due to their extremely sensitive hearing.
