■ Comments
I’m Eir Aoi, who will be in charge of the 4th season opening theme song.
When it was decided that I would be able to sing the opening theme song for “Tensura”, which continues to be loved from all over the world, I was really surprised.
Above all, I couldn’t stop being excited. “Illustration” is a fierce rock number that snuggles up to the magnificent scale of the work.
I hope you enjoy it with the anime.
As I get involved in the work, I felt a lot of passionate thoughts and feelings of enjoying the story together.
As a fan, I am also looking forward to seeing what the future of Tempest will look like.
Let’s continue to love the world of Tensura together!

■ Comments
I’m CION who will be in charge of the 4th ending theme song.
Rapid is a song that has a solid sound that envelops the end of the anime, and a song that has “dry and strong feelings”.
In the anime, I was encouraged by the appearance of Rimuru, who has increased the number of friends with his ability and kindness, and created this song.
I hope that I can help you with the thoughts of everyone who loves the work.
I will do my best to make this 4th work more lively with music!

[4th Introduction]
The Demon Federation (Tempest), which held an opening festival and formed diplomatic relations with each country, set out to realize a world “Human Demon Co-Prosperity Zone” where humans and monsters can live together. The Demon Federation (Ruby: Tempest) that crosses the walls of the race, holds hands and prospers.
However, behind the scenes, there were those who viewed the rise of the Demon King Rimuru as dangerous. The former “brave” Rosso, the head of the Five Elders of the Siltrosso, and his granddaughter, Maria Bell Rosso. Granbell and Mariabell, who advocate the protection of humankind under control, go on a plot and clash with Rimuru. On the other hand, in the Golden Land of Eldorado, the Demon King Leon begins to move for the purpose. A hero who is the guardian of mankind and a demon king who rules the world. A single “hero” was about to awaken in the midst of various speculations.
Rimuru’s next battle begins with a feeling of non-negotiable feelings.
