Anyone else think of Yuusha's 'explanation' from 'Be Mine Hero! I refuse!'? The part where he's attempting to teach a few people the sword and uses sound effects and feelings to describe it, then blows a hole in a mountain with a single slash? "He's too talented to teach" was the excuse, lol.
Side note. Will a ghost even be able to use the aura of a body it snatches? I get that the energy comes from the body, but its the mind that knows how to use it. I could understand in litrpg's due to everything being instinctive once learned, but...
