Lupin is the main character in this series which takes place in Italy and San Marino. Reflecting its setting, the anime debuted in Italy before it aired in Japan. Lupin III fans will note that the titular thief now dons a blue coat, following his earlier appearances in green (first series and some OVAs), red (the second series as well as most films and television specials) and pink (third series).

Denji is robbed of a normal teenage life, left with nothing but his deadbeat father's overwhelming debt. His only companion is his pet, the chainsaw devil Pochita, with whom he slays devils for money that inevitably ends up in the yakuza's pockets. All Denji can do is dream of a good, simple life: one with delicious food and a beautiful girlfriend by his side. But an act of greedy betrayal by the yakuza leads to Denji's brutal, untimely death, crushing all hope of him ever achieving happiness. Remarkably, an old contract allows Pochita to merge with the deceased Denji and bestow devil powers on him, changing him into a hybrid able to transform his body parts into chainsaws. Because Denji's new abilities pose a significant risk to society, the Public Safety Bureau's elite devil hunter Makima takes him in, letting him live as long as he obeys her command. Guided by the promise of a content life alongside an attractive woman, Denji devotes everything and fights with all his might to make his naive dreams a reality.

Though Gundam Plastic Models, better known as Gunpla, exploded in popularity with the release of the anime series Mobile Suit Gundam, their presence faded before resurging with a new purpose. Through the power of Plavsky particles, fans are now able to pit their Gunpla against others in a virtual reality-style battle with the best competing at the annual Gunpla World Tournament. Sei Iori, whose father was a once finalist in the competition, dreams of one day conquering the contest himself. However, while Sei is an expert Gunpla builder, he lacks the prowess to effectively fight his creations during actual battle. In comes Reiji, a mysterious boy who is curiously ignorant of society but quickly demonstrates to Sei tremendous ability in Gunpla battles. The two boys decide to combine their strengths in order to sweep the Gunpla World Tournament and take the Gunpla world by storm.

A technological hell masquerading as paradise, Tsukimihara Academy is an artificial high school that serves as the setting for the next Holy Grail War.
