Gennul

Appearance
Gennul has the appearance of a large wolf with wings. The wolf can also clad its body in white and purple lightning.

History
Gennul was born from the legends and rumors of people being spirited away. At the Spirit's Institution, Gennul takes away those who failed their tests in order to take make-up classes. Prior to Anos' arrival to Aharthern, Gennul had already spirited away his subordinates and those of the Four Evil Kings.

Great Spirit Arc
After the students of the spirit class earn the right to take the Spirit Trial, Gennul appears as an obstacle before they can meet with the Spirit King. The wolf immediately allows Lay and Misa to pass, but stops Anos and Eges. To proceed, the two work together and defeat Gennul.

Abilities

 * Vanishment: As the spirit of vanishment, Gennul can make itself and/or others disappear. The rumors state that those spirited away are either hidden at the world's border or inside Gennul after being eaten. The spirit wolf can bring them back when it needs to.

Spirit King
The Hidden Wolf is the Spirit King's watchdog. If he gives the order, then Gennul will return those it took away.
