Fuuka-chan After 18~20 years old

This is great.

In the original, her 2nd birth was twins also.

@king_midas The math says yes. Assuming she only had twins once that's 6 births, that should be possible in 5-6 years though extremely unlikely..

18 my ass anyone who unironically reads this should be shot

You see that Japanese, 7 kids under 20 isn't impossible.

She should get heroic medal for saving Japan from crisis

Hot. She's saving Japan's birthrate all by herself.
