"What's that, 'Mutating Skeleton Grafting Technique'?"
"A higher discipline of White Bone Spirit Summoning Studies. Are you sure you want to hear about it, Kevin? It will waste some of your time."
"Wasting time? I'm not short on time. Look, I've run to the graveyard in the middle of the night. Oh, I'm not targeting you guys because you're doing legitimate things. I mean, I'm free right now."
At Kevin's reply, the bird-beaked Lyle chuckled helplessly under his mask, always so during his student years, filled with curiosity.
"Higher White Bone Spirit Summoning Studies, to put it simply, is the study of skeletal mutations. The skeleton of the Eternal Hound capable of traversing space-time can also be considered an abnormal mutated bone. Mutated bones can be artificially created. The ability to transport is one kind of mutating factor."
