After all, Pan Gongjin was an experienced fighter. From the last fight, he completely understood Han's power and his style.
In conclusion, Han's power was most likely a unique power that could grant him immunity towards other powers. Another possibility might also be that it was some mind-controlling power that restricted enemies from using their abilities.
But regardless of what power Han had, he needed to get into melee range in order to kill, and that was his only method of combat.
A merciless smile surfaced on his face, Pan yelled, "This guy isn't scary at all. Everyone follow me and storm him at once! Let's finish him!"
Right after the sentence, the 11 raiders that were still alive followed Pan Gongjin and charged at Han.
One against 11 enemies, which also included a 4-star esper. This was clearly a hopeless fight.
