|Four Leaves Technology|
|Full Name||Four Leaves Technology|
|Leaders|| Shiba Tatsurou (Director of Development) |
Ushiyama (Chief of CAD Development, Third Division)
|Associated Individuals||Taurus Silver|
Four Leaves Technology (フォア・リーブス・テクノロジー) is publicly known to not have been a manufacturer of CAD products, but rather a provider for spare parts used for Magic Engineering, but their ascent to the pinnacle of CAD development and production around the globe is largely in thanks to the Silver Series. 
The official company records and brand name intentionally use only "Four Leaves", which is often shortened to "FLT". 
FLT is a corporation secretly funded by the Yotsuba Family, and even though Shiba Tatsurou was the major shareholder, in due part to the stocks from his deceased wife, Shiba Miya, the actual power of attorney still remains in the hands of the Yotsuba Family. 
Once seen as rebels and renegades, the surplus employees from the technical department that made up the Third Division now hold considerable sway in FLT after the advent of the Silver Series. 
The development team that created what the world calls the "Silver Series", however, Tatsuya is half of Taurus Silver.
Thus, the engineers and researchers here swore eternal loyalty to one of the core developers — Tatsuya, who was "half" of Taurus Silver, and was responsible for software advancement.
The successes of Third Division created animosity and jealousy in the company, and the workers at the FLT main branch derided them as "Captain Taurus and his companions". 
Taurus Silver (Public Image)
- Main Article: Taurus Silver
Taurus Silver (トーラス・シルバー) is depicted by Azusa as a genius
middle-aged CAD engineer who was never once seen by the public. He is the first person in the world to develop the "Loop Cast System", and later on the "Sustained Gravity-Control Type Magic" (Flying-Type Magic). He is also described as someone that advanced CAD software technology by ten years within one short year, raised the speed of Activation Sequences for Specialized CADs by twenty percent and reduced the variability of wireless models from 3 percent to less than 1 percent.
He openly publicizes his findings for the betterment of the magical community as a whole, instead of solely profiting from it or gaining fame. 
The Silver Series are specialized CADs made by Taurus Silver, and is publicly acknowledged as the defining work of FLT's technical abilities. It's the best CAD for incorporating Loop Cast.
Silver Horn is the name of the Fully Customized Specialized CAD developed by Taurus Silver.
|“||Silver Horn Custom "Trident" . This was Tatsuya's favored instrument, that which brought out the finest of his magic. Tatsuya squeezed the Trident's trigger. His original magic, the military secret "Decomposition" activated. He had incorporated three consecutive Decomposition magics into one Magic Sequence and completely annihilated a Magician's flesh and body along with its naturally occurring magic protection barrier.||”|
Loop Cast System
Loop Cast System is the Activation Sequence that skips the step of restarting each Activation Sequence. If the Magic Sequence is the same, then the CAD no longer has to restart the Activation Sequence each time. This is done by adding a copying power to the Magic Calculation Area's execution mode, adding a copy of the Activation Sequence's last parts to the Activation Sequence itself, so Magicians can endlessly invoke magic within their ability. 
Sustained Gravity-Control Type Magic
A recently made revolution to modern magic was created by Shiba Tatsuya when he created viable Flight Magic.
- It is a type of general-purpose CAD which doesn't have any interfaces on the main body and can be used without any external input devices. The connector, however, has a grip and auxiliary aim assist system attached.
