History
Göndul is known as a great magician and Valkyrie in Norse mythology. She was the one to raise her grand daughter Rossweisse in the country side.

The Legend of Oppai Dragon and his Lively Companions
Göndul made her first appearance in Volume 17 as she visited the Hyoudou Residence to visit her granddaughter Rossweisse and came to confirm her granddaughter's relationship with Issei Hyoudou. She also scolded Rossweisse for agreeing to be reincarnated as a Devil on her own accord.

Göndul then went to the Underworld to be a special lecturer to the children in the school Sona's building before attending the Magician's assembly. After some time, Qlippoth started their attack and managed to surround Agreas and Auros in a barrier and placed a seal on Göndul and the other Magicians to prevent them from casting most of their spells. Even with most of their magic sealed, they were able to create a teleportation spell in order to teleport all the civilians outside the barrier but it was a ploy by Qlippoth to be able to use that spell to teleport the whole floating island of Agreas instead.

When Euclid Lucifuge was about to kidnap Rossweisse, Göndul appeared and tried to save her granddaughter but she was too fatigued from fighting the traitorous Magicians who altered the teleportation spell. With the last portion of her power she altered Euclid's teleportation spell and stopped him from escaping. She then pleaded to Issei and Rias to save her granddaughter.

After all the battles were settled, Göndul had a talk with Issei and Rossweisse before she left and told Issei to take care of Rossweisse.
