Yuuri has written a new song titled "Thunderbolt" as the opening theme for the upcoming anime 'Thunder 3,' which premieres on July 8.

Based on the manga by Yuki Ikeda, the series follows three middle school friends—Pyontaro, Tsubame, and Hiroshi—as they search for Pyontaro's mischievous younger sister, Futaba, after she goes missing.

Yuuri's "Thunderbolt" will make its debut during the anime's first episode. Meanwhile, the ending theme, "Shururerira," performed by singer-songwriter Otoha, will be released digitally on July 10.
