Shikkakumon no Saikyou Kenja
The Strongest Sage with the Weakest Crest, The Strongest Sage of Disqualified Crest, Shikkakumon no Saikyokenja, 失格紋の最強賢者, ปราชญ์หนึ่งในใต้หล้ากับตราสุดอัปยศ, 失格纹的最强贤者
At birth, mages are randomly given one of four "crests" that determine their level of magical ability. A man named Gaius received a crest specializing in creation, which allowed him to reach his full potential and become known as the world's strongest sage. Despite possessing immense power, he was still dissatisfied with his abilities and yearned for a mark suitable for close combat. Since a person's crest cannot be changed, Gaius decided to reincarnate into the future in hopes of altering his fate.
Thousands of years later, Gaius is reborn as Mathias Hildesheimer and successfully obtains the crest he had long desired. However, he is shocked to discover that magic has significantly declined in these times, with techniques once widely used now being nothing more than a mere legend. Additionally, the crest he worked so hard to attain is now considered the weakest, simply referred to as the "Crest of Failure."
Despite this setback, Mathias excels in every trial at the royal capitals Second Academy. However, after discovering that humanity's decline into magical mediocrity was caused by demons, he resolves to rectify the consequences of his millennia-long absence once and for all.
