Follows the misadventures of four irreverent grade-schoolers in the quiet, dysfunctional town of South Park, Colorado.

Living in an area known for its juvenile crime, 21-year-old Makoto has become a member of a youth gang called the G-Boys. Known for his cool head and ability to get things done, Makoto becomes a key troubleshooter for the gang by diffusing tense situations and keeping his friends out of harm's way. However, the death of his girlfriend and an escalating turf war with a rival gang threaten to be more than Makoto can handle.

In the middle of a hot summer, a homeless woman is murdered in the centre of Ljubljana. At least as much as her death is troubled by the fact that the murder took place in a park right next to the General Police Administration. In addition to Taras's and Tina's relationship, resentment is being drawn from the events at Lake Bohinj over Taras' treatment of the spoiled son of an influential man, so the head of Drvarič assigns the management of the case to Tini instead of Taras. The start of the investigation is not the most promising, as none of the occupants of the park detected anything unusual, even though the windows look out of all the apartments. Yet a criminal investigation reveals that one of them wasn't the most honest.

Rilakkuma, Korilakkuma, Kiiroitori, and Kaoru are off on an adventure to the theme park, but with closing time imminent it leads to a series of fun mishaps and incidents as the group squeeze a day of fun into tiny amount of time.

Seiya Kanie, believes that the beautiful but reserved Isuzu Sento has invited him on a date at an amusement park called Amagi Brilliant Park. Much to his chagrin, not only is the location a run-down facility, the supposed date is merely a recruitment tour where Sento and Princess Latifa Fleuranza, the owner of the theme park, ask him to become the park's new manager. Their cause for desperation? As stipulated in a land-use contract, Amagi has less than three months to meet a quota of 500,000 guests, or the park will be closed for good and the land redeveloped by a greedy real-estate company. Seiya is won over by the revelation that Amagi is no ordinary amusement park; many of its employees are mysterious magical beings who live in the human world and are nourished by the energy created by people having fun. Entrusted with the hopes and dreams of this far-off enchanted land, Seiya must now use his many skills to bring Amagi back on its feet, or watch it crumble before his eyes.
