"It's related to the Ghost Face Gang — a shady group active in the underworld of Academy City. They always skirt the edges of the law, doing small-scale bad deeds.

They've managed to survive pretty well because of this." Suoga explained to Tilan, recounting the events, which were more or less similar to what happened with Duke. One night, members of the Ghost Face Gang blocked As's convoy and forced them to betray, leaving behind plenty of evidence.
