Four Leaves Technology (フォア・リーブス・テクノロジー) - often shortened to FLT, is a Magic Engineering Corporation (Magical Engineer Equipment-maker Company) where Shiba Tatsuya and Shiba Miyuki's father, Shiba Tatsurou, serves as the developmental section chief. It was later revealed that it was a company started by their deceased mother Shiba Miya.
