Y2K

"Mankind has become too dependent on the things they've invented, using them as an excuse to become lazy and ill-trained. I wonder what would happen if such inventions would rebel against them?"

Y2K (, Wai Tsū Kē; lit. "Modern-Era Technological Apocalypse") is an extremely dangerous magic, branded forbidden due to its effects on the ever-growing evolution of mankind's inventions; it's such, that's its branded as the "Technological Bane" (技術対極, Gijutsu Taikyōku) by the upper echelon of the Magic Council, the only ones outside of Suoh's Ten Lightning Generals who know of its existence.

Alternatively referred to as the Mass Hacking Magic (質量計算機不許可の魔法, Shitsuryō Keisanki Fukyoka no Mahō), it's a Caster Magic and a Subspecies Magic — using and deriving from the basic concepts of Archive; according to Fern Larseniux — one of the Ten Lightning Generals and the magic's current and only user, this magic was originally invented by his boss during his heydays as a test subject of the Magic Council — an application of his incredulous electrical powers. Upon complete mastery, it was deemed as a cast-off and passed onto Fern when he joined his then-"ragtag group of misfit youths", believing that he had the capabilities of mastering such a powerful force — a fulfillment that became true some time later.

Trivia

 * Originally, he wanted to make the user quite.... plain. However, this was decided against because of his desire the reason why he's held his position in the group for quite a duration; also, it plays into his role as a "hacker" — serving as a bane to all things technological within the FTVerse.
 * The idea was originally meant to be a form of Requip, but was revised into this magic as the previous though was deemed "retarded", thus slated completely.
