User blog comment:Miskos3/Fairy Tail Chapter 385: The Celestial King vs. the Underworld King, Review/@comment-24784846-20140523135851

I think Lucy should learn magic to merge with her spirits, would be a great power, maybe it would be called Celestial Take-Over Magic or Celestial Merging Magic, somewhere there.

I think CSK vs Marde should not have an ending mostly because CSK is OP and Marde still has more purpose such as reviving END, but the fight was really good, please expand on this Hiro!

As for Lucy vs Jackal thing, she needed a way to beat him and she inherit(maybe) Aquarius's magic, and then used Urano Metria to beat him. Logically Urano Metria is a powerful spell, I think it is reasonable that she defeated him with that spell.

The next chapter sounds like something to do with the CSK, who knos, but I give 4/5 reason being it needed to expand on CSK vs Marde Geer
