It’s interesting to learn that every sorcerer has a small tumor in their head that embodies their soul. It makes sense why En is interested in the ability to reanimate life. Though it appears that using one’s power as your own is very looked down upon. Well, funny enough, he has a new pet for a partner.
For both Caiman and Nikaidou, they are now in the world of the sorcerers. No doubt Nikaidou is nervous because her friendship with Caiman is special. At the very least, it seems clear that she isn’t the one that “cursed” Caiman. One would think that the secret of her being a sorcerer wouldn’t discount their friendship, but coming clean is the hardest step because of the fear of it not working out. Still, she is much more powerful than she has let on so far.
The fact that Shin’s gang hopes to lead them to Caiman has the name Risu. At the very least it is clear there is some connection between him and Caiman. Though one thing the end of the volume showcased is that En is by far the most dangerous sorcerer if he is out of control.
