Riko Sasaki performs the opening theme song for the TV anime "As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World Season 3," which starts broadcasting in October 2026. Themed on "the importance of staying true to your beliefs," it is a song that depicts a heart wavering between ideals and reality. It is a powerful, fast-paced alternative rock number. It contains three songs in all, including the title track "Still Water". The Anime Edition features a newly drawn illustration jacket.
