Description:

In an ideal world where man and robots coexist, someone or something has destroyed the powerful Swiss robot Mont Blanc. Elsewhere a key figure in a robot rights group is murdered. The two incidents appear to be unrelated...except for one very conspicuous clue - the bodies of both victims have been fashioned into some sort of bizarre collage complete with makeshift horns placed by the victims' heads. Interpol assigns robot detective Gesicht to this most strange and complex case - and he eventually discovers that he too, as one of the seven great robots of the world, is one of the targets.

Strangely enough, his head-gun is designed so that only someone behind him can pull the trigger. Juuzou makes a living by taking on cases involving Extends in the city, and he is assisted by Mary, an intelligent young woman that he has taken under his protection. (Source: MU)

Description:

With the space program attempting to travel to Mars, 21st century scientists were tasked with warming up the planet so that humans could survive on its surface. They came up with an efficient and cost effective plan of sending cockroaches and mold to the surface so that the mold would absorb the sunlight and the insect corpses would serve as a food source for the mold. It is now the year 2577 and the first manned ship to Mars has landed on the planet and the six crew members are ready for their mission. But what they find are giant mutated humanoid cockroaches with incredible physical strength. The crew members are easily wiped out, but not before sending a transmission back to Earth. Now, humanity will send elite warriors to exterminate the mutated bugs and claim back Mars. (Source: MangaHelpers)
