they have been doing it for 4 years now onstage so .... 8D
yesterday on DAIGO P , DAIGO was promoting X X X (he was waving the copy of the CD + DVD of the single every single walking min) which was really cute xD
even Acid Black Cherry's yasu was saying that he was currently in an X X X mood too haha , it's cute that both guys were helping to do free PR for L'arc if you ask me x)
