Taken my sweet time making this list compared to the other ones. Mainly was busy writing the first chapter for Season 4 before writing this. Also the difference in rankings was a bit tougher to tell as Season 3 as a whole was just overall tedious to work through compared to the variety of qualities in the previous seasons. By the time of writing this, the next chapter is already done so no need to worry about waiting much longer
1. Kaijuno's Bizzare Misadventures Inviting the Other Demon Lords
2. 3 Star Audience
3. Grudges of reserve and multi pervs
4. Violet Bonding Part 2
5. Settling Back
6. Festive Activities
7. Festival Beginnings and Demon Lord Mingling
8. The Light Speed Hero and the King of the Monsters

10. Concerning Matters and Preparations for the next Venture
11. Labyrinth Opening and Festivel Send Off
12. The future is now old man
13. Time for round 2
14. Tournament Arc Baby!
Honestly Season 3 felt more of a drag. I really wanted to skim through a lot of the material just to move on the next season. But I feel it would be a injustice to the source material if I just skipped most of the stuff
Overall just a burnout of a season for sure
