Overlord Blu-ray 05 Special is a compilation of Various Overlord Material. It was released on January 27, 2016 in Box 5 of the Blu-ray & DVD Collection.

Main Summary
This special contains a small collection of rough drafts in regard to mostly characters of Nazarick. This includes the Floor Guardians, Sebas, Narberal Gamma, and Clementine. Additionally, it features a very short bonus manga concerning the interaction between Pandora's Actor and his creator, Ainz.

Full Summary
In the bonus manga, Ainz begins to wonder what to do against the unknown threat that brainwashed Shalltear. Realizing that Super-Tier Magic won't work with the said World Item, Ainz tries to figure out what his enemy's objective is and how to find countermeasures around it.

At the same time, Ainz felt that his job as the master of Nazarick is tiring and hopes to take a break. In the meanwhile, he confronts Pandora's Actor and questions him if whether or not the doppelganger could transform into him. Right away, Pandora's Actor took on his creator's form and before Ainz can fully say his question, the doppelganger assumes he wanted him to be his body double.

Additionally, Pandora's Actor believed his practice and training in acting as his creator will finally pay off and now seems to rehearse his lines to Ainz. While so, Ainz now regrets asking for help from Pandora's Actor and thought it was a mistake on his part.

Trivia

 * Supposedly, the event happening in bonus manga seems to happen after Light Novel Volume 3.
