The boys call themselves Sphinx and carry out plans to destroy Tokyo—unless someone can solve the bizarre riddles they share with the city. This, of course, sends Tokyo into a panic, though they do end up befriending a young girl named Lisa Mishima who helps get to the heart of their dalliances with terrorism: an investigation into the Rising Peace Academy, where both Nine and Twelve hail from.
