Gacktophile
A gacktophile is someone who would die for gackt, even if it means getting stuck in a toilet
My brother is a gacktophile. He sat in a toilet for 2 hours watching gackt.
I saw a gacktophile in the park. He was singing to gackt like it was a lover.
My neighbor is a gacktophile. He yelled at me for not liking gackt.
