One of the BEST series out there in Vocaloidandia is the Dark Woods series.
Simple Summary: Miku is locked up in a cage by Meiko, goes insane, Meiko deforms her and somehow they get to circus, she hates life, kills everyone, goes to hell, and becomes a reaper.
I'm making a wistle in Ceramics that is Guard and Scythe/ Red Swamp Bottom themed.
Love you guys!
