Located on the outskirts of Tokyo, Hachimitsu Private Academy is a prestigious all-girls boarding school, famous for its high-quality education and disciplined students. However, this is all about to change due to the revision of the school's most iconic policy, as boys are now able to enroll as well. At the start of the first semester under this new decree, a mere five boys have been accepted, effectively splitting the student body into a ratio of two hundred girls to one boy. Kiyoshi, Gakuto, Shingo, Andre, and Jo are quickly cast away without having a chance to make any kind of a first impression. Unable to communicate with their fellow female students, the eager boys set their sights on a far more dangerous task: peeping into the girls' bath! It's only after their plan is thoroughly decimated by the infamous Underground Student Council that the motley crew find their freedom abruptly taken from them, as they are thrown into the school's prison with the sentence of an entire month as punishment. Thus begins the tale of the boys' harsh lives in Prison School, a righteous struggle that will ultimately test the bonds of friendship and perverted brotherhood. [Written by MAL Rewrite]

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. [Written by MAL Rewrite]
