"Oh? What did you come up with?" My other self tilted her head, curious what kind of idea I had thought of.
"Well, Mana comes from the soul, and technically right now we should be in our soul form, I guess." It wasn't too far-fetched since this dream-like state might be an illusion created by the cube Tyso put me in.
"That makes sense, I don't have a physical body, so this must be just my soul taking form." My other self looked down at herself, trying to see if there was a way to tell, but other than logic, there was no way to confirm visually.
"Yes, so my idea was that we try to merge our mana together. I don't know if there is a specific way, but I think this will work." If what Tyso said is correct, then souls are just lumps of mana. I have no clue about the biology of it all, but I'm guessing it's similar to genes, where souls are comprised of fragments of our parents' mana.
