The technology to create powerful cyborg soldiers has been released for public use by the Berühren Corporation. Those outfitted with robotic parts are known as the Extended. Juuzou Inui, one such Extended, was created as a soldier and has no memories of his former life. But now, after the war, he runs a business that takes care of Extended-related incidents around the city. Rumors of a renegade Extended that kidnapped a child reach his ears; lo and behold, as Juuzo returns to his office, a giant robotic man with a boy on his back crashes in, asking for help. While Juuzou could just turn the guy in and be done with it, something about this situation is too fishy to ignore. It seems that everyone wants hold of this kid and, whether he likes it or not, Juuzou must find out why this Extended is on the run, how it connects to the Berühren Corporation, and just how far the treachery runs in this city.

Second half of No Guns Life.

More crazy antics abound as Nozomu Itoshiki (a.k.a Zetsubou-sensei), who is the worlds most negative person, tries to teach class 2-F about how life is filled with despair and darkness. A harder task than it first may seem, with his students being far from ordinary themselves, including the likes of the most positive girl he has ever met, his very own stalker, a foreign exchange student with split personalities and a perfectionist acting class president, due to the fact the real class president can't be seen by anyone, among others.

Nozomu Itoshiki is a high school teacher so pessimistic that even the smallest of misfortunes can send him into a pit of raging despair; some of these "catastrophes" even lead to suicide attempts. Sayonara Zetsubou Sensei is a satirical slice-of-life comedy set in the modern day, covering various aspects of Japanese life and culture through Nozomu and his interactions with his students: Kiri Komori, a recluse who refuses to leave the school; Abiru Kobushi, an enigma who frequently arrives to class with severe and mysterious injuries; the hyper-optimistic Kafuuka Fuura, Nozomu's polar opposite; and several other unusual girls, all of whom are just as eccentric as their teacher.
