Day 6: Your favourite PV.
Probably Guren since it has such a contrast of light in the dark (or in this case red and white) and just the way all the members are displayed is perfect.
Day 19: Your favourite Aoi picture.
OH GOD JUST LOOK AT HIM HES SO PERFECT
Day 13: Your favourite The GazettE era.
Early GazettE, like when Kai joined the band.
