Looks like the story is coming to a close with only one more chapter to go! Now that Professor Yamagishi and Kana have turned into some grotesque abomination, it wants to mate with Keiko and borrow her womb for some unknown reason. My guess is that Yamagishi wants to rebirth himself again or something like that. It’s not a pretty sight.
It’s also interesting to note that the Professor left the base sequence of the Cambrian virus inside the walls of the Manic bars underground labyrinth. Almost as if he wanted the virus to be cured at some point.
