Ch.56: another what if... of Kyouko, also a Tanuki TF.
Ch.63: BE, actually overall growth too. She goes full devil woman after being possessed. So far one of the unresolved arcs along with the Pierrot killer.
Ch.70: Bodyswap-TG. Actually is just transfer between adult Masaru and Ayumu, I think they first appear around v07 of the original manga. Nube is ruthless.
Ch.72: Headswap between Kyouko and Miki, another what if... Kyouko and Miki are still in their respective bodies, they swap jobs instead.
Ch.75: Oshiroi Baba AR, she seems to be Mamoru's grandmother but I am not sure.
Ch.78: Just Kyouko faking her body to meet with Hiroshi, I guess the last time they were together they were still kids.
Worth mentioning that 20 years later the time travel chapters were repurposed to show the POV from their adult counterparts, it also set in stone that Kyouko wouldn't grow into the body she wanted.
