I guess that August was right after all, he could only be defeated by his mom, while not directly it was her who made him stop that last spell. He had a similar fate as Eileen. Larcade poor guy he was killed by the person he believed to be his father. The two strongest remaining Spriggans had been erased/disintegrated. I do admit being angry that Mavis now will never know about her child, maybe Hiro didn't want to explain how Mavis got pregnant so choose to have August kill himself and move on with the arc.

Wonder what Mavis will do with the Book of END and why Gray didn't told her Zeref true intentions.

Last panel with Natsu and Zeref was pretty cool.

Next chapter tittle is the Demon Dragon, is referring to Natsu or Acnologia. Hopefully is Natsu becoming into a Etherious-Dragon Hybrid, but that is just me hoping for something unique and unexpected to happen.
