so the question is if both Lotte and Asuha are 10 and have the same mother, are they twins? or do Succubus not take 9 months to give birth, i mean it was implied that Asuha took 9 months given that MC was visited 11 years and 4 months ago and Asuha is 10 and not 11, sure she could maybe get pregnant again right after giving birth but i was thinking there was a time frame after giving birth before you can get pregnant again and its not like just a week or 2.
