Not sure why this is tagged mainly as an Ahemaru work, it's clearly Kyozow all the way through. The only Ahemaru drawing here is a small flashback panel in page 12.
And not to diss the new guy, but in my honest opinion the quality of both this series and Slave the Blood has gone downhill since they switched main artists. I don't know if Ahemaru is too busy or something, but it's too bad.
