Fujiko, Fujio F.

Doraemon is cat shaped robot from the future traveling all the way back to the 20th century in order to help Nobi Nobita, a lazy kid with nothing really going for him. Nobi is bad at sports, his grades are terrible, he can't even win a match of rock-paper-scissors. Doraemon has a hard task ahead of him but he is well prepared with a huge arsenal of the most inventive and funny gadgets available. The problem is he's not the most competent robot cat helper out there either and the pair gets in constant trouble because of it. Thus begins one of the most interesting friendships ever to appear in a manga series.

In the near future, large mecha called Labors are made to assist in various reconstruction projects in major countries around the world that are being threatened by global warming. In Japan, the government has enacted Project Babylon in order to conduct land reclamation. Labors are also being pressed into police and military service aside from civilian use.

However, terrorists are now attempting to use labors to make themselves heard, as well as common criminals, thugs and guerrillas. The National Police Agency established the Special Vehicles Division, an all-labor task force to combat the potential use of labors for criminal/terrorist activities.

真夜中エクスプレス

Park, Suhlah

Choi Sera houses displaced aliens in her home, where they all pretend to be UFO fanatics in order to explain their eccentricities. Sera's job is to teach these aliens how to live in human society—not that difficult on the surface, as they ostensibly look like humans (except for the three fingers on each hand thing). They look normal, and they can communicate with earthlings via a translator that looks like a hearing aid, but can they act normal? The answer to that is a resounding no. Watch as Sera tries to school the emotionless twins, Seunghyun and Seungmin (really clones) on dating (with disasterous results), tries to keep Hyunwoo out of trouble, and keep them all from being taken away by the UN alien hunter who's on to them.
