In Martian colony Fourth Tokyo lies a classroom of Kirishina Corporation's brightest minds spearheading aerospace development: A-TEC, led by genius engineer Kaito Sera, eagerly anticipating the arrival of their newest member. It soon becomes clear, however, that the transfer student is hardly ordinary—Nagisa Kiryuu, newly appointed chief of A-TEC and the younger brother of the corporation's CEO, is sent to shut the program down. To keep the classroom alive, Kaito and his students desperately work to develop a successor to their most powerful rocket, the X-2; meanwhile, Nagisa climbs the corporate ladder in pursuit of his own mission. In spite of this, their separate battles soon reveal that much more is going on in Kirishina Corporation than meets the eye. Classroom☆Crisis follows Kaito and Nagisa, as well as Kaito's younger sister Mizuki and A-TEC's test pilot Iris Shirasaki, in a story of intrigue, political warfare, and, against all odds, romance. As Nagisa and A-TEC are dragged further and further into Kirishina Corporation's conspiracies, friendships grow and pasts are unveiled as they fight to avert their classroom crisis.

Set in 2142, Wonderful Days depicts a world that has been nearly destroyed by environmental pollution. Human life as we know it is almost extinct, and only a few were able to pull through the collapse of Earth's ecosystem. In order to deal with the chaos, a city named Ecoban was created. The city uses the very pollution that caused the disaster as an energy source.

However, although the initial plan was successful to an extent, it didn't just create a new source of energy, but also an elite group of people. This prestigious faction believes that they are above the system, and are not willing to accept survivors from outside the city unless they are put to work as laborers.

Among the people living in the wasteland outside Ecoban is a young man named Shua. He leads a very difficult life, but tries to make the most of it through the love that he feels for his childhood friend Jay. Unfortunately, Jay may be more interested in her security commander Cade than in Shua, and thus a love triangle is formed. Not only does Shua have to deal with the heartbreak, but he must also find a new way to survive in the crumbles left from the once-beautiful planet Earth.
