This has the be the most all encompassing Light Blade/Penlight ever released for the Love Live Franchise. This one alone has 26 colors and accounts for all members across Aqours (9 members), Nijigasaki (12 members), and Liella (5 members). Operating the light is simple, just hold the smooth button at the bottom to turn it on and push the same button to change colors going clockwise; The grooved button changes colors counter-clockwise; The triangle switches between the three groups (Aquors -> Nijigasaki -> Liella) and the small oval button turns the smaller light on/off. The blade is powered by three AAA batteries. A great purchase if you need a blade for any of these groups!
