After an extensive search, I could not find any information on a musician named Adachi Kumi. It's possible that there may be a typographical error or confusion with another artist's name. For instance, there is a Japanese rock duo called Love Psychedelico, consisting of vocalist Kumi and guitarist Naoki. Additionally, there is a Japanese actress and singer named Yumi Adachi. If you can provide more details or clarify the artist's name, I'd be happy to assist you further.
