Well with the symbol on the girls eyes it is fully confirmed the man-eater in the garage in Ch.19 is in fact Ohma. That is sad that she as a man-eater was able to get back to Mimihime, who was above inside the building but couldn't be together. I wonder if Shiro could tell it was Ohma or not. I do wonder if it will ever get back to the missed baby that Maru didn't see that was growing under a car, or if we are just to assume that the group that took over will all be killed eventually.
Kuku, now with the illness, seems to likely have been the fish monster on the boat, she did want the picture of it, maybe she sure turned into it because she saw it from Kona's picture or was always going to be the fish monster in the first place.
Also the two on the last page seem to likely be Taka and Anzu with Tokio being name dropped by the woman I doubt its one of the younger kids since they never knew Tokio.
