Though their first song, "destiny", was a pop-rock number, since the release of "High and Low" in 2013, their music has come to incorporate more sounds from electronic and dance music. The members wear gas masks and leg warmers in a style combining elements from
steampunk and
cybergoth fashion. On stage, they carry distinctive prop guns (called "Laser Gun" and "Steam Gun") that fire laser beams and clouds of dry ice together. Unusual for the pop music industry, member Tomoka Igari is a
wheelchair user. She participates in the choreographies normally, as far as her condition permits, performing the upper-body movements and position changes.

Slimes, the first monsters a player encounters in games like
Dragon Quest and some versions of
Final Fantasy and
The Legend of Zelda. Slimes have therefore become a
cultural icon in Japan representing low level or beginner tasks.
