Death by Smoking Butterfly
This is the shaggiest of our short black wigs, and the back hair covers the neck more than the other styles. It works well for Tyki Mikk from D-Gray Man, Harry Potter from Harry Potter, Gilbert Nightray from Pandora Hearts, and young Walter from Hellsing.
It also works for rather a lot of Homestuck characters, including Gamzee Makara (see below), Karkat Vantas, Kankri Vantas, Aranea Serket, Kurloz Makara, Mituna Captor, and Jake English (see below).
