The anime adaptation of Rusted Armors, a multimedia project that first started with a stage play and a manga adaptation. The project focuses on the relationship between the gun-toting Magoichi — who is the leader of the Saika Ikki mercenary group — and the Sengoku era warlord Oda Nobunaga.

His name is Lupin III. He is a gentleman thief whose grandfather was the renowned phantom thief Arsène Lupin. When it comes to the art of thievery, there is nothing Lupin III cannot steal; whether it be jewels, works of art, hidden treasures, the secret to immortality, or the heart of a pretty girl. Lupin's partners are Daisuke Jigen, a great gunman; Goemon Ishikawa, a master swordsman; Fujiko Mine, a devilishly clever femme fatale. There is Inspector Zenigata, a relentless ICPO officer, consumed with an obsessive desire to apprehend the masterful thief.

In a world of magic, the powers and future of a mage are predetermined at birth through so-called "Marks"—four symbols that categorize a human's aptitude for magic. Lamenting the fact that his mark was considered ill-suited for combat and only useful for magic augmentation, an incredibly skilled sage decided to reincarnate thousands years in the future. Reborn as Mathias Hildesheimr—a six-year-old boy and the third son of a duke's family—he attains the mark of close combat he always desired. Unfortunately, it is also discovered that mankind's knowledge of magic and swordsmanship has drastically deteriorated in this era; only shoddy magic equipment can be sporadically found, while even the most basic spells have been forgotten. To add insult to injury, his current mark, once hailed as the most powerful, is now viewed as the worst. When Mathias becomes 12 years old, his unrivaled swordsmanship lands him in the Second Royal Academy. Shattering prejudices, he promptly makes ripples in the academy and beyond. However, the former sage uncovers signs of dark forces working in the shadows, and with humanity weaker than ever, it is up to Mathias to thwart their evil plans.
