Wolfgang Schneider

Wolfgang Schneider (볼프강 슈나이더) is a Closer of the Wildhüter using the 'Black Book,' a mysterious grimoire, as a main weapon. He fights the enemy by summoning evil spirits or weapons of dimensional monsters sealed inside the book. Wolfgang himself has balanced abilities. He is a competent Closer who can complete any mission based on his wealth of experience. Usually, however, he lacks the motivation to do so.

Background
Wolfgang found the Black Book when he was a rookie closer. He was on a mission to retrieve a bag from a dimension monster with his senior and was successful. When checking what was inside the bag he found the Black Book. Upon touching the book, the book spoke to him saying 'I'll give you power, I'll give you power if you open me...'. He then subconsciously opened the book and Eligos appeared and killed his senior.

This could be why despite being having the code-name Librarian, one of his dislikes is the Black Book.

Trivia

 * Despite the Black Book containing many sealed dimensional monsters inside, Wolfgang only fully summons Eligos, Belial and Shub to fight with him.
