Fifty years ago, an extraterrestrial giant of light known as Ultraman saved the earth but vanished. Ultraman's human host, Shin Hayata, was left with no memory of his time as a hero. Hayata's young son, Shinjirou, is found to have been born with a more powerful and durable body than any normal human. The organization who aided Ultraman, the SSSP, reveals Hayata's past to him. His father then dons a power suit again, assuming the role of Ultraman once more. One night, Shinjirou is attacked by an alien named Bemular and rescued by his father, who is severely injured in the battle. With dangerous aliens lurking in the city and Hayata out of commission, it falls to Shinjirou to pick up the torch. But in working with the SSSP as the new Ultraman, Shinjirou finds himself wondering how far is he willing to go to help people.

In a dystopian future, detective Shinjuurou Yuuki—known by some as the Defeated Detective—solves mysteries throughout Tokyo. Aided by his odd associate Inga, Shinjuurou's insight and ingenuity in cracking cases, particularly homicides, lead to numerous mysteries solved and culprits caught. However, his partner seems to have some other, more sinister intentions for the people they catch, and the truth of the assistant's identity and motivation is shrouded in secrecy.

When aliens known as the Oni threaten to invade the Earth, they promise to leave under one condition—a randomly-chosen human must win a one-on-one game of tag against Lum, the beautiful daughter of the Oni leader. The lucky person selected happens to be the lustful and unlucky high schooler Ataru Moroboshi. Given 10 days to attempt to grab Lum's horns, Ataru realizes how impossible the challenge is as he is faced with Lum's extraterrestrial powers. Motivated by a promise of marriage from his childhood friend Shinobu Miyake, Ataru manages to catch Lum off guard. He mistakenly grabs hold of her bikini top first, but he eventually achieves his true goal. Although the game is over, Lum misunderstands that she is the one whom Ataru wants to marry, and she decides to move in with him. The poor student constantly tries to shake off the clingy Lum while doing his best to reconcile with his desired fiancée. After Ataru's heroic feat results in such a disastrous outcome, it is questionable whether luck will ever be on his side.
