After Sakura Mizukami shows up at the Kazama household to ask for a favor, Kenji Kazama and his sister Noe end up unwillingly participating in a footrace at the local shrine. Intent on winning the prize—spring water that only appears once per year—Sakura recruited the Kazama siblings to guarantee her victory. But when Sakura's clubmates, Chitose Karasuyama and Roka Shibasaki, enter the race as well, the girls' competitive energy is unleashed and the contest immediately develops into an all out battle where no victor is certain. What's more, Noe, fed up with Sakura's constant teasing, has no interest in helping her win, and the battle rages not only on the field, but between the divided team members.

Based on a manga by Tanimura Hitoshi, serialized in Comic Burger. Teenager Kanemori Kousuke is a secret agent for the international VN spy network. Using his computer hacking skills, he tracks international criminals. Later he goes after Neo-Nazis to the Arctic were they try to raise a U-boat with a sinister secret.

After a meteor hits Earth, traitor forces have (for all intents and purposes) taken over, and the people are suffering. In the chaos, a boy named Tetsuro Daiba, who had lost his parents in the meteor hit, is paid a visit by Mello, a mysterious woman appearing in a bright light. When Daiba comes to, he finds himself in a spaceship infirmary under observation. Stealing a fighter that he didn't know how to pilot (until he tried it), he breaks out, flying like a total pro. He was able to remember how to pilot from his DNA memory... and to find out more, his doctor friend takes him to his secret underground lab, in which he acts as a professor to find out ways to stop the traitor regime. When the forces invade to take him back, a girl named Rei Yuuki mysteriously shoots down their entire carrier with only a fighter jet! Apparently, both have mysterious powers that the enemies want, which may or may not be connected to their being the only two known survivors of the meteor impact. While looking for a third survivor (which turned out to be a cat), the two are taken by force to Queen Photon (ruler of the traitor regime), who claims that she is out to SAVE the Earth from those who sent the Meteor. The two don't know whether to believe her or Mello until the (telepathic) cat breaks them out of the Queen's sealed chamber, and Mello comes to straighten things out. That's when the two (er, three) of them make a choice... Stay on a planet that can't support their advanced race, or strike out into the unknown of space?
