▼OP Theme Song - Comment from Eir Aoi

I'm Eir Aoi, and I will be performing the opening theme song for Season 4.
When I learned that I would be singing the opening theme song for "TenSura," which continues to be loved worldwide, I was genuinely surprised and, more than anything, couldn't contain my excitement. "Esoragoto" is an intense rock number that complements the grand scale of the series.
I hope you will enjoy it alongside the anime.
While being involved with this work, I felt the passionate feelings of everyone and the sense of enjoying the story together.
As a fan myself, I'm looking forward to seeing what kind of scenery Tempest's future will show us.
Let's continue to love the world of TenSura together!

▼ED Theme Song - Comment from CiON

We are CiON, and we will be performing the ending theme song for Season 4.
"Katsubou" is a song that layers "feelings so strong they parch" over a heavy sound that envelops the anime's ending.
We were encouraged by Rimuru's figure in the anime, who increases his companions through his abilities and kindness, and created this song.
We hope to empathize with and support the feelings of everyone who loves this series, even just a little.
We'll do our best to energize this Season 4 work through music as well!
