Their 38th digital single "BAD Idenshi" released on July 8. They shared the following comment about the song on the anime's official website : Since we received a request for "a grand parent-child fight," we created a song that captures the overflowing frustrations of adolescence. The few centimeters it takes to understand each other feels so far away. Yes. I understand. I felt that way too when I was in junior high school. I wonder if I will feel the same way when I become a parent someday. With extreme aggression and and a small amount of love and yearning for affection. I hope many people will listen to this song.
