Asuna is the princess of this world and would be instantly regocnized as there are statues of her in the magic world. The fact that it hasn't gone public that she was found means ... someone might have captured her or ... a friendly person is hiding her from the bad guys.
Konoka and Setsuna ... hmmm ... since Setsuna is a creature girl she must have come from her to begin with even if she doesn't realize it. I think it would be so cool if she found herself back home and took her new gf to meet her parents. LMAO! You know that would work in this manga! It would be so funny. Konoka is special as well.
Ah! Anything could happen.
