Elysia was on her way to the battle with the demon king, if she was lucky she might be able to hold the demon king off for two or three days and get Aaron to come to her.
The descent of a god into a human body was an unbelievably heavy event, which had only happened a few times even in the history of the heavens, and each time it had resulted in the person fainting or dying. Unfortunately, in this short period of time, he would not be able to say goodbye to Aaron, whom he could call his best friend, and he would not even be able to say goodbye to Dumgrith, who was indeed his best friend. It might have been seen as a very bitter fate for an angel, but Elysia would go to a better place with all these pains and this rudeness of reality.
As Beelzebub said, "hell or heaven". These two would open the door to Elysia's final journey, now she just had to fight and move on without looking at the glittering and glorious perfection behind her.
