Titus Annaeus Secundus (ティトゥス・アンナエウス・セクンドゥス) is the Chief Librarian of library within the Great Tomb of Nazarick.


A skeleton that seemed to be made of a mixture of human and animal. Titus had a height of about 150 centimeters, with two demon like horns grew out from his head, and four fingers on its hands. His legs were extended directly and his feet were warped.

He wore saffron colored himation. And with one clothe of his hood, it was positioned so that it would not break on one horn, and an another was wrapped around his body. He was basically wearing three of them.

With a platinum bracelet with gems of seven colors, a golden ankh cross hanged from his neck, his bone fingers had several rings, and the himation wrapped around his waist was embedded with gems. They were all average magic items. A sword hung from his waist, several scrolls hung from there as well.


A studious individual that busies experimenting.


Titus is a Skeleton Mage and the Head Librarian of the Library in Nazarick.[1]


Overlord First Half Arc[]

Main article: Overlord First Half Arc

The Chief Librarian was busy working on creating Magic Scrolls using YGGDRASIL gold coins. He was visited by Ainz Ooal Gown, who witnessed one of his scrolls burst into flames. The librarian apologized for the unsightly scene and explains that for the sake of preserving Nazarick's own sheepskin parchment, he has been trying to use the sheepskin from the New World. Alas, a simple parchment could be made into a scroll that could hold Rank 2 spells, but it could not be made into a scroll that held higher. He believed that the necessary instructions for the manufacture of this world's scrolls was needed. However, Ainz decided to freeze the project for the time being so the librarian obeyed.[2]

However, Demiurge managed to acquire "sheepskin" from his ranch in the Abelion Hills. The results he received from the materials showed that the first to third tier magic can be stored but no higher. Still, it was a significant development as Nazarick can now solve the problem of making low level scrolls.[3]

Abilities and Powers[]

Titus had no remarkable fighting abilities but was an existence that a former member of Ainz Ooal Gown made to specialize in crafting. Since there were no investments on his racial levels, his magical job levels were high. In truth, his total level was way above an elder lich. In addition, he was among the individuals in Nazarick that could see through invisibility.[4]


Ainz Ooal Gown[]

Like all the other NPCs in Nazarick, Titus is loyal to the last Supreme Being.

Fluder Paradyne[]

After Fluder Paradyne became Ainz's disciple, he was introduced to the human mage and became contemporaries.[5][6]


  • In the Light Novel, his discoveries are told to Mare Bello Fiore rather than Ainz.
  • In addition, he appears more in the Web Novel, attending the court of Nazarick more often to report his findings rather than stay in his library like he does in the main work.
  • Like his mainstream counterpart, he has an elder lich serving him named Librarian J.
