Magnum Solis

Magnum Solis (Latin for "Great Sun") is a half-god (not a real God, but considered one by the Blue Midnight members and Great Sunset Tournament's participants) that lies in Regnum Mundi. It is considered the absolute God of Regnum Mundi, similar to Sōsuke Aizen's position in Las Noches.

Magnum Solis has an array of titles: he/she is the Supreme Leader of Blue Midnight, the Host of the Great Sunset Tournament and God of Regnum Mundi.

Its current appearance is unknown.

Succession and Crowning
Magnum Solis is an absolute entity until the moment someone defeats him in battle. The one who beats him/her gains the power and title of Magnum Solis, Absolute God of Regnum Mundi and Bringer of the Eternal Glory, King of the Lost and Pure Souls, Guide of the Sun and Moon, Master of the Clouds and the Rain and Supreme Leader of Blue Midnight.

The crowning takes place in Blue Midnight's Leader's Headquarters. Three pots are carried by three chosen Senior Members. One has the blood of the former Magnum Solis, the other, its sword, the ancient Will of the Gods and Earth (神大地の意志, Shindai-chi no Ishi), only wielded by Magnum Solus and the last one, its soul. The three are put in front of him and the Leader proclaims his sayings for the crowning. The blood is taken with his/hers finger and the kanji "封" (Seal) is written in the Great Scroll, that is opened by the Leader. The soul of the former God is grabbed and put in the middle of the kanji. The sword is then taken and stabs the soul and the kanji, sealing it away in the scroll.

All Blue Midnight's Senior Members gather in a circle and put their hands on the ground. A giant energy sphere appears around the newly crowned Magnum Solis, similar to Negácion, and he is then taken to his throne in Regnum Mundi.
