@HarmlessDave there is incredible lots of depth in that side story.
In the web novel original Benza just grows into the person within the premonition, without much explaination but that he was appointed by Allen as liason => gang leader /misunderstanding and suddenly the people flocked to Benza. It was unclear whether they followed Benza just because of Allen.
But that part of Benza described in that side story, completes the image which was lacking in the web novel. A little too much with the "premonition part" for my taste, but that also fits the story so far with all the teasers of this and that what is still to come in the future about the unicorn class.
If people liked the action and pacing of this volume - they can look forward for what is to come. It is like the plane has finally took off regarding the momentum.
In Japan there are currently up to six volumes available. And I like the next two very much too - with even more to be expected after that.
