When the Sky turns Red, the Moon turns Black, and monsters begin roaming the streets, Satsuki Kakeru is at a loss for what to do. Along with his best friend Yuka, they try to decipher why they have been sent to this strange world, which is seemingly empty aside from themselves.

They meet four others in the same predicament: Kusakabe Misuzu, an expert swordswoman, Tachibana Kukuri, a strange mute girl who looks uncannily like Kakeru's deceased sister, Hirohara Yukiko, a lively young girl whose personality reverts to that of a cold killer when her glasses are removed, and Tajima Takahisa, a young pyrokineticist. As the six of them band together to survive and discover what this mysterious world is, things take a turn for the worse as six shadows appear before them... [Written by MAL Rewrite]

The pilot episode for Tiger & Bunny released on the first DVD & BD volume.

Dr.Haneda was developing experimental giant robot warriors to fight the allies during the Second World War, but before his creations could see action, Allied bombs destroyed the facility and killed him. A decade later criminals discovered two of the surviving prototypes, #26 and 27 in the series, and used the remote controlled robots to commit a number of crimes. Young Shotaro Haneda, the twelve year old son of Dr.Haneda, did some investigating and discovered that the mob were hunting for the twenty-eighth robot in the series, rumoured to be the most powerful of them all. Racing the villains, Shotaro discovers the robot first, along with Dr.Shikashima, a colleague of his father's who was also believed killed by the Allied bombing. Together the two prevent Tetusjin-28 (the robot's official designation) from falling into the hands of the bad guys, and decide to dedicate him to peace rather than war. Shotaro fought crime for a long time, supported by Dr.Shikashima, who would repair Tetsujin-28 when he was damaged, and by police officer Otsuka. Shotaro even battled the alien Magmans, invaders from the planet Magma, who came to Earth late in his career, bringing their own giant robots, Magma X and Gold Wolf, with them. (Source: AniDB)
