Season 1 of Battle Through the Heavens is better than Season 2. The anime has a great story, but the live-action version was disappointing, and the characters weren't strong.
Those who create and use Battle Through the Heavens cosplay are better than the costume designers in this series.
Why aren't you using costumes that match the anime and follow its storyline? Is there a budget constraint for custom costumes? Kindly request assistance from cosplayers to ensure the provision of excellent costumes.
