SUPER?GiRLS' new single "Bubbling Squash!" will be released on August 15. 

"Bubbling Squash!" is a love song that compares a shy girl's feelings of being unable to express her feelings to the bubbles of a sweet and sour fruit squash. As this will be the group's first summer single in about two years, they plan to have various projects this summer. 

The single's limited edition will come with "Hero," which is the theme song for the movie 'Tokyo Living Dead Idol,' as the bonus track.
