Yagami-kun no Katei no Jijou

Synopsis

In short, the mother appears to be around fourteen years old, and her son is openly in love with her—a combination of lolicon and mother complex. His teacher is also in love with the mother, so the romantic rivals clash in the classroom and scheme to bring down their common enemy, the father. The father has a secretary who is in love with him, but after discovering that he has such a young-looking wife, she shifts her attention to his son. The son now finds himself torn between his own mother and a naive girlfriend who rides a motorcycle. Later, a new student arrives in class who looks exactly like the mother, and everyone falls for them—except that the student is actually male. The Yagami-kun OAV has a strong likelihood of being the only anime where the production video (included with some episodes) is more interesting than the anime itself. And the claim that it is a low-budget manga spin-off anime aimed at exploiting the existing fan base is not an exaggeration.
