★yousti Profile

Kobayashi Yui passed the first generation audition for Keyakizaka46. After being renamed Sakurazaka46, he has long led the group as a popular member. Graduated from Sakurazaka46 in 2024. One year has passed since the group graduated, and from now on, he will continue his self-produced musical activities as “yousti.”
The artist’s name is youthi, which contains the message that he should not try too hard, sometimes run away and surrender himself.
This coined word is a combination of “yui” and “ostrich”, which means “escaping reality.” “Ostrich” is a word that means ostrich, and is used as a slang to represent “escaping reality” because “ostrils hide their heads in the soil when they feel a crisis.”
Also, “i” to me, “you” you are the finest “st”. It also contains a message to fans.
