Eiro sat in the library, playing around with his new shadow magic a bit. It was hard to really do anything but manipulate the two-dimensional form of the shadow at the moment, but at the very least, Eiro was still able to properly infuse himself with shadow magic, so he could really stop using the Shadow magic stones and could instead use them for other things. Like give them to Gobo when he was too annoying to deal with and he needed a bit of a bribe to just shut up for a while.
The demon looked past the shadow that he was currently trying to cast onto his skin while surrounded by multiple light sources, trying to increase the level of this magic skill rather quickly, and stared at the two monsters sitting in front of him on the ground.
