Although everything the young duke touches perishes, his existence is far from lonely. His spirited siblings Viola and Walter, loyal butler Rob, and the eccentric witches Cuff and Zain are regularly livening up his secluded mansion. But it is the duke's flirty maid, Alice Lendrott, who fills him with the promise of a beautiful tomorrow and the determination to break this hellish spell cast upon him. The identity of the witch who cursed the duke has been uncovered thanks to Zain's unique magic and the help of Daleth, the leader of the underworld. However, the villain is a notoriously fearsome and powerful witch, who, enraged by the duke and his companions' trip back in time, torments them even from the afterlife. Moreover, an unexpected loved one reappears, strengthening the duke and Alice's hope to break the curse and finally close the distance between them.

Far in the future, the human beings were pushed into the deep underground world called Labyrinth and they are living shoulder-to-shoulder. The Labyrinth has several colonies with severe settings such as one having an insanely high temperature, while another is full of gold and silver. Among those, in a colony of Pinyin, resides a curious nine-year-old girl named Memempuu and her father Gaganbar. As "workers" aiming for survival, they live with the lowest profession of riding a working robot to dig ore. One day, Memempuu pestered Gaganbar, a cave examiner who makes maps of the internal part of Labyrinth, to go travel together with her to find her mother. As a "marker," Gaganbar holds the most dangerous yet attractive profession. One step outside the colony is already deemed to be a dangerous area and meeting a huge mysterious creature that loiters the cave, one's chance of living will be cut down to five percent. Since it is a dangerous racket to explore the unknown world, the map they hold is valuable and can be sold at a high price. However, is the price for their curiosity higher? What could be the cruel truth that is hidden among them? What awaits at the end of the test? In this travel story between a father and a daughter surrounds adventure with family love.

Gintoki and his Yorozuya friends (or rather, employees suffering under labor violations), Shinpachi and Kagura, continue to scrape by in the futuristic, alien-infested city of Edo. They take on whatever work they can find while trying not to get involved in anything too dangerous. But when Katsura, the leader of the Joui rebels and Gintoki's long-time acquaintance, disappears after being brutally attacked by an unknown assassin, Shinpachi and Kagura begin an investigation into his whereabouts and the identity of the assailant. Meanwhile, Gintoki takes on a seemingly unrelated job: the blacksmith Tetsuya requests that Gin recover a strange and powerful sword called the Benizakura which was recently stolen. As the two investigations gradually intersect, the Yorozuya crew find themselves in the midst of a major conspiracy that hinges on the sinister nature of the Benizakura sword. Gintoki resolves to take the fight directly to the enemy headquarters, and together with a few unexpected allies, sets out on one of his most perilous jobs yet. [Written by MAL Rewrite]
