Whelp, if after all that his coworker decided be so dumb to let this crazy stick it in her, I don't care if she gets choked once he decides to return to his beloved vampire-succubus. Also why didn't they investigate him again for the assault on the banged-wrist girl is they realized he was accomplice to murderess? Poor girl was the only not-shitty character.
The fact that mangaka pushed absolutely pointless, especially at this point, three-page domestic abuse sad backstory for the mysterious succubus/assassin femme fatale proves that more faithful translation had no chance to save this story. What was that even for? At least I learned some new words out of this train-wreck.
