Both its A-side and B-side tracks are featured as opening and ending themes for the second season of the anime series Shakugan no Shana.

In 2007, Kawada was pleased to be asked once more to write theme music for the upcoming second season of the anime adaptation entitled Shakugan no Shana II.

[2] Its story is focused around Yuji Sakai, an ordinary Japanese high school boy who inadvertently becomes involved in a perpetual war between forces of balance and imbalance in existence.

In the process, he befriends the title character Shana, a female fighter for the balancing force, and one of his classmates named Kazumi Yoshida.

However, rereading the script, Kawada interpreted the work as an attempt to show that our world too is frail and could crumble at any moment as evidence by the many accidents that occur daily, which appear on the news.

[2] In an effort to convey the mental state of both Yuji and Shana, Kawada tried write the lyrics to her two songs so as to "capture the world as seen through their eyes".
