poor giorno II... tormented by his own stand ability :(
his stand can generate almost any wavelength of light and it can expel the light from its fingers and eyes (and giogios fingers and eyes too) but the light that comes from his eyes is especially strong and will temporarily damage his eyesight so he refrains from doing it that much
this was supposed to be my own stand ability but i think it is much more fitting for giogio since its kind of main character-ish (plus his name means day...)
