The Hero's Weapon, "Daikon"

"Goddess-sama, there's something I want to ask you about reincarnation into another world."

'You’re about fifty lifetimes late, but go ahead.'

"Can you reincarnate just one part of a body into another world?"

'I think your common sense has already reincarnated into another world.'

"Do you think it’ll come back?"

'I think it’s already lived out its natural life and moved on to the afterlife. Besides, what would be the point of reincarnating a body part with no sense of self?'

"You know how a new weapon or part sometimes gets sent over? I thought it might be interesting if it were sent over through reincarnation instead of being transported."

'Even if it were theoretically possible, reincarnating the part you need would mean it gets reincarnated, so it wouldn’t be the part you wanted anymore.'

"Oh, right. If someone said, 'Here comes a new face!' and the face that arrived belonged to someone else, they’d have grounds for a complaint."

'Don’t make me picture a children’s superhero show.'...
