At this point, Roger had no choice but to split his focus, directing most of his attention to the Elder of Shadows, striving to break free from Kurokawa's control in a short time, and then assist in dealing with the riffraff surrounding him.
Indeed, with the dominion displayed by the Elder of Shadows, these Fourth Tier mid to high-level monsters were truly just riffraff.
It was only through actual combat that Roger realized the Superior Leader's strength.
When it came to physical prowess, Kurokawa surely couldn't compare to the Elder of Shadows, but Kurokawa was lucid, able to exert his full strength.
