So why “SLICE!?”
Mostly because it fucks with people’s punctuation when they ask questions like that.
But really, the name just seems kind of obvious. “SLICE!” is both an apt descriptor of what our heroine does and what she carries.
Manga readers amongst you might recognize that it’s a reference to Tsutomu Nihei’s fantastic sci-fi action epic, BLAME! The title Blame! is actually a mistranslation, it’s pronounced “BLAM!” as in the sound effect.
