I usually dislike zombie animes, but I think H.O.T.D. balances violence and drama so well.
My favoritve character is Saeko, I'd love to see someone cosplay her. I'd love to see anyone cosplay Saya too! She's a bitch, but I love her character because she reminds me of my own snobby girl-ness. I want to cosplay a girl with glasses, so I might do her sometime in the future.
