Master Logos
Master Logos (マスターロゴス, Masutā Rogosu)[1] was a title held by the leader of the Sword of Logos.
Overview[]
The title of Master of Logos was first used by the original founder of the Sword of Logos, who was among the first humans to enter the Wonder World. Master Logos' successors each swear to protect both the Almighty Book and the world. Whoever holds the title of Master Logos leads the Sword of Logos' swordsmen and has complete access to the organization's forbidden tomes. Every Master Logos is related, as each successor is chosen from a specific clan. As stated by Ryoga Shindai, it has been the duty of Shindai family to protect each Master Logos for generations.
After the final battle for Earth, the title of Master Logos was abolished by Sophia, allowing a council to make the decisions of the guild.
Known holders of the title[]

Notes[]
- According to Storious, the name Master Logos is actually a title. Yuri later confirms that there were other holders of the title before the current one.
- Sophia tells the Shindai siblings that the seat of Master Logos will be abolished, and will be replaced by a council system. This makes Issac the last person to hold the title of Master Logos.
