Eiro stood in front of Koperia, showing off this merged form of his, "When I became the candidate for 'The World', I got an ability that allows me to easily fuse with magic and the elements, and since spirits are basically both of that just come to life... I can fuse with them. I could feel that the undead's powers worked in a weirdly similar way, so I was able to fuse with it. Although it seems like I couldn't stop it from trying to physically merge with me." Eiro pointed out as he rubbed his face where he had to rip the mask off of his skin just a few moments earlier.
Koperia crossed her arms and thought, "At this point, I already gave up on making you my toy, but... Would you mind letting me... 'analyze' that ability of yours? I've been trying to fuse different undead with each other for a long time, so that ability of yours should help me figure out how to proceed."
