Mysterious Girlfriend X was a very… interesting series. Sure, it was a little trashy. It had a great nostalgic feel to it, though. Some things it nailed, like the awkwardness of teenage romance. Other things were less successful, like the whole shtick about Urabe stripping naked at school only to have Tsubaki see her. The one thing the show constantly nailed was focusing on various fetishes as a means of fanservice. Episode 9 was about hair, and it was good.
