Build a rainbow. Again and again. - Hold this up to the sky with this side facing you.
L'Arc~en~Ciel is a band celebrating its 30th anniversary, and its name means "rainbow" in French. "Rainbow" is a song that has a deep meaning for the band and their fans, as it was released when L'Arc~en~Ciel restarted after their hiatus. At the time, the members said that a rainbow is like a flower that blooms in the sky when the rain stops and the sun comes out. In 2021, the year of COVID-19, society was depressed, people were isolated, and so to speak, the whole nation of Japan was on hiatus. Based on the experience of overcoming the suspension, L'Arc~en~Ciel sent out newspaper advertisements that made rainbows appear when people held them up to the sky. The message that people should look up to the sky and make a rainbow during these difficult times resonated with them, and many people looked up to the sky that day.
