HY guitarist Miyasato Yuhei has withdrawn from the group. 

Miyasato had been taking a break from his activities since May due to his poor heath condition. On the group's official website, he wrote, "Personally, I hope to recuperate and slowly find my own path. I want to continue playing the guitar." 

As for HY, they will continue their activities as a four-member group.
