RPG Insanity

I am at part 86 in the story.
 

After beating the game I restarted and exited the final dungeon according to part 85.  I went to the start of the Sky Castle and went to the left (west) and into, what I guess is Akegarass Lands? It was a short extra "dungeon" with one extra boss at the end.  I beat him and got Part 86, but not sure where to go.  Any ideas? Thanks.

It says "ongoing" in the quest list.

 

Thanks

 

What you can do now is to repeat the final boss battle against Sharl inside Sky Castle Demonxia while Lily is equipped with the Gold Spirit Armband that you found in Akegarass Lands. By doing this, you can now choose the Happy Ending option "Journey to purify Aura" at the end.
