I started reading this series where the main character was a genius hacker despite only being in high school. His alias during his forages into cybercrime was "Hawk" or "Falcon" (depending on the scanlator) and his family name contained "Taka" in some form. Anyone know of this series, since I lost my files, and now I can't find them anymore. Thanks for any leads.

Bloody Monday?

Why, thank you.
