When Ryuurou (23) was pregnant with Kiyoshi, he virtually had no bump until the sixth or seventh month. Which is a big problem when he has no clothes to accommodate his sudden growth.
Natsume (38), the father of Kiyoshi, has no experience with caring for a pregnant partner, let alone one carrying a child with a special ability. (Not that any of it matters unless Ryuurou delivers the child he was promised (we'll get into that more later)).
Natsume's parents (58, 60) step in, having birthed and raised numerous children, particularly children with similar abilities to Natsume.
They weren't aware of Ryuurou's existence let alone the child he was carrying until Natsume dragged him to their doorstep.
They have a heavily pregnant up and coming mafioso in their house and a son who may or may not even care for said mafioso. (you can imagine how much more enraged they are when they find out that Natsume had abandoned Kaede (5) in their home (though it does explain why Ryuurou keeps crying out at night and attempting to crawl out of the house)).
Thankfully despite Ryuurou not being allowed to see a doctor, Kiyoshi is born relatively healthy. A strong healthy kit.
..Something both Natsume and his parents forgot to mention to Ryuurou.
