If we get Baby Rentaro, the whole chapter will just be the other girlfriends trying to restrain Hahari before she gets her hands on him
She wouldn't even be that much different than usual, she'd just be trying to breastfeed him and changing his diapers. Hell, the bigger risk would probably be her soul leaving her body repeatedly and Mei and Nano needing to constantly stop her from nearly dying to cuteness overload.
We are really at the point where 6 of the 33 characters don't feature at all.....
It's not anything new. We've had dozens of chapters now where Rentarou hasn't shown up, and just as many where the whole of the Rentarou Family doesn't appear. Only feels noteworthy here since it seemed like the chapter
was trying to cram in everyone even if they weren't relevant, like having Suu, Kurumi, and Karane briefly appear in Mimimi and Mei's section, or Hahari and Eira watching Saki and Shizuka, or Iku in Mai and Kishika's section, so it makes it more noticeable that five of them didn't even cameo when it seemed like they
were trying to fit everyone in. Heck, it wouldn't have been hard to change some of the overlapped girls, like changing Mai's cameo in Hasuha and Uto's part to be Nano, or including Yamame in Kusuri and Momoha's part since Momoha did briefly mention her.
