Well, this game happened.
> "The long and short of it is that I recently gained the ability to create 'contrasting existences'. I can use it to make clones of people, as long as the clone is the opposite of the original in at least one fashion."
> Gesture at Raiko 2.> "She is a clone of the original Raiko Horikawa, altered so as to be opposite the original in a certain area."> Gesture at Benben 2.> "And she is a clone of the original Benben Tsukumo, who is over there."> Gesture at the original Benben.

> Adopt a thinking expression.> "...Maybe? I can't promise success, or even that trying won't unexpectedly affect you in different ways. But I might be able to, if you want me and accept the potential consequences."
> "All right, that's fine."
> "Right, yeah. Wakasagihime, does any place in particular look good to you?"
> "Let's head to the back and check it out, then."> Head to the back of the house.
> Examine the plants.
> What kinds of plants are there?
> Can we tell what kinds of fruit?
> "Oh, yeah, I see there. What kinds of plants are they?"
> "...They make that?"
> "Huh. I guess that's pretty appropriate for you, huh? Anyway, let's see what we have for water options back here."> Have a look around the immediate area for what might make for a good pond location.
> Look back to the mermaid.> "What do you think, Wakasagihime? Looks like you've got your pick of the land here."
> "I wonder if it's possible to somehow connect a larger one outside to a smaller one inside."
