I'm just curious about the nen balls that Razor creates, are they just emission or does the fact they explode make them transmutation related as well? I don't read the manga and the only anime i've watched is the 2011, but i'm useless when it comes to reading spoilers :( so i am aware that Bloster has a similar ability and was just wondering do his nen balls explode?
