Rei Yasuda "Hikari no Sumika" Music Video Ruri Rocks Creditless Opening Video Rei Yasuda was born in North Carolina in April 1993, and made her solo artist debut in July 2013 with the ending theme song "Best of my Love" for Star Blazers: Space Battleship Yamato 2199 . Since then, she has also provided theme songs for The Irregular at Magic High School , Natsume's Book of Friends , and Love All Play . Yasuda shared the following comment on "Hikari no Sumika" on her official website when it was announced in May: I wrote the lyrics for the opening theme song, "Hikari no Sumika." After reading the original manga, I was reminded by Ruri-chan and Nagi-san of the reason why I feel power from the natural stones that I wear every day like a talisman. In this "Hikari no Sumika," I projected myself in the eternal time it takes for such gems to be created and the mysterious, miraculous process woven by nature, and wrote the lyrics the lyrics using the metaphor of "jewels" to express the strong will to find and reach "what is missing in oneself" and "proof of being alive," even if it takes time. I'm looking forward to the start of Summer Adventure (broadcast)! "Hikari no Sumika" released digitally first on July 6, and will also be included in her double A-side CD single "Hikari no Sumika / BROKEN GLASS" to release in Japan on August 27.
