When Hansa reached the rooftop, he received a submachine gun baptism.
Jester made the police special forces weapon, which he must have borrowed without anyone noticing, spit out a hail of bullets. At the same time, he let loose with a shotgun — also police equipment — in his left hand. A quantity of projectiles sufficient to make mincemeat of any ordinary man closed in on Hansa.
Just then, however, Hansa’s body seemed to sway like a heat haze. He evaded most of the bullets without even using his Black Keys, and batted some of them out of the air with this own hand. The scene, straight out of an action movie, drew unaffected praise from Jester.
“Indeed, of all the executors I’ve seen, you are the top of the class!”
