KIRAMEKI, also known as "Your Lie in April," is a beautiful song featured as the first opening theme for the anime series "Shigatsu Wa Kimi No Uso." Originally written in the key of G major, it was composed by popular Japanese musician and songwriter Takeshi Saito. The song is performed by the talented group wacci, consisting of members Yoshiki Sakurai, Hikaru Yamazaki, and Kazuki Anzai. Interestingly, KIRAMEKI holds a special place in the hearts of fans as it was used as the first opening for the anime, setting the tone for the emotional rollercoaster that the series presents. The melody of the song is both gentle and melancholic, reflecting the bittersweet themes of love, loss, and the transformative power of music that are central to both the anime and the original manga upon which it is based.
