As a Xmas gift, here you have a Butterfly Chronicles promo video. The sound track is Moonspell's "I am the eternal spectator" from the "Butterfly Effect" album. The manga has a Moonspell gig along the story. Remember: Hanako is a Moonspell follower. In the last video image, you can have a look at the real Hanako with me ;).
Hanako, the Butterfly Chronicles' main character, loves Heavy Metal music. In one part of the story, Hanako goes with a friend to a Moonspell gig. Here you have one of the cases of that very gig, where you can see Moonspell lead singer, Fernando Ribeiro.
