Unfortunately, the fate of the Celestial of Lightning is still sealed. It is just a level 4 Celestial while she is a level 5 demon king. The fact that it can now spot her and attack her directly doesn't remove the disadvantage of strength. It has only stopped the succubus queen from toying with it until it dies.
The succubus queen formed a barrier around her that protected her from the field of lightning and the target lightning strikes while she empowered her whip with more power to deal deadly blows. The level 4 defense of the Celestial couldn't save it from being threatened.
