Mother Parasite, 3

After hitting Sanae with a vase and knocking her unconscious, Ryota provoked Rika's compassion and very cleverly settled into the Kasai home. However, Kaoru saw the strange smile that Ryota smiled that night and now distrusts him. Kaoru is afraid and tells her mother, but Rika no longer sees her son. Then, as Ryota's plan progresses step by step, a third mother appears before him!
