Quit geeking out!!Flt. Lt Ishida in Luminous!!The penlights changed to blue and red during the solo part!The outfit she wore on the day were chic black and white, but I wondered if they had been choose to avoid an overlap with Luminous's member colors.
Luminous uses symbols like their unit emblem to evoke the image of "stars illuminating the night sky," but Ishida-san could be likened to the white light of the sun, perhaps?
