Once their conversation had come to an end, Neo wished to leave as quickly as possible to go and check on his disciple.
To aid with this, Karizen snapped his fingers and brought them over to the place where he had sent Yether.
Earlier, he had been unable to do so since he had brought Neo out of Asmodeus's world without his permission.
To enter the heavenly realm, one would either have to be a God or someone close to a God.
Neo's anger towards Karizen at that moment would hinder him from entering the heavenly realm.
Not to mention that he was a demon whose entry was already barred from that place.
However, this time, through Neo's acceptance which acted as an entry permission for Karizen, the two immortal beings were able to enter the heavenly realm.
Though confused, the guardian of the heavenly gates allowed them to enter after seeing that Neo was letting the Demon Lord accompany him without any pressure from the other man.
