In this story setting based on "Faust", Mephisto is the demon who tempted Faust and coveted his soul in the original work. He once made a bet with God that Faust would fall and his soul would belong to him. Wandas is the God in the setting and has a love relationship with Mephisto.
The story line is therefore different from the original work. Mephisto did not get Faust's soul as smoothly as the original bet. In the end, Valdas, as God, handed over Faust's soul to Mephisto, and wrote this ending for this story that started out of a bet and twists and turns due to the special relationship between the two.
