Finding himself diving head first into an inter-dimensional mess, Sam realizes that sleeping with robots was the least of his concerns.

Valkyrie Smash

"Say…" Nino spoke, asking a question that has been on Sam's mind. "If she really is my sister, what does that make me?"

"Does the name Lachesis ring any bells?" Sam asked.

"Hm? A little bit… I think? I remember hearing it in…" Nino's eyes became saucers as she suddenly came to the realization. "Atropos had two sisters! Lachesis is the middle one!"

"Apparently that's what she called you back then." Sam said.

With everything he had heard so far, Sam hypothesized that, after she was killed by Atropos, Lachesis somehow reincarnated as a Valkyrie and became Nino. Her memories of her previous life seem to be gone, but not completely.

"Lachesis…" Nino murmured to herself. She then looked at Sam with a difficult expression. "I've been wondering for some time now but… does this mean I have already died once?"

"Then how am I here? Isn't death supposed to be the end?"

Reincarnation.
