Comments from Kubo-sensei (google translated): Intention Behind the Selection of Theme Songs for the TV Anime BLEACH: Thousand-Year Blood War Arc I personally selected all the theme songs for the TV anime BLEACH: Thousand-Year Blood War Arc from the demo stage. I wanted to have as many new artists as possible handle the theme songs throughout the series. I also wanted viewers to discover these artists through "Thousand-Year Blood War Arc" and become fans from there.
Reasons for Choosing joOji's "I-BULL" as the Final Season Opening Theme For the final season, we received more song proposals than ever before. Since it was the final season, I wanted a song with impact. I already liked joOji's music, and there were a few parts in the demo that I wasn't really keen with with, so I asked if it was possible to improvise them. joOji responded with "Absolutely," so I gave him some requests like "I like this part" and "I really like this part," and he came back with something that was almost like a completely different song. It was really good, and it felt like we got it right on the first try.
Reasons for choosing 9Lana's "Rasen" as the Final Season Ending Theme Among the proposals we received during the initial demo stage, this song is way above the rest in terms of quality. We decided at that stage that we would definitely use this song for either the opening or ending theme. The melody is great, the lyrics are great, the arrangement is great—the song itself is of very high quality. It could be used for either, but I was hoping that a song of this quality should be used for the ending. The intro is fantastic, and I thought it would be wonderful if it smoothly transitioned into the end of the story.
