Furuki

Furuki is a driver connected to Shunsuke Otosaka's syndicate, forced into service at a hidden facility after his family is taken hostage. Threatened with their deaths if he refuses, he agrees to deliver Kumagami and later Yuu Otosaka to a group of foreign operatives waiting at an abandoned factory.

Furuki's role is small but morally grey: he is neither villain nor hero, simply a man cornered into cooperation. Once he completes the delivery, the group hands over the key needed to free his family, closing out his brief but tense involvement in the plot.
