To be quite honest, the DXD and Hellsing part left me quite absorbed in reading, but when it got to the Harry Potter part... It left me disappointed, it's as if the story went from 100 points to 50 in the blink of an eye. Harry being Rose Potter, and good nature characters actually being evil? Very cliché, there are already so many stories like this that it has lost its charm. And Valeria literally telling Rose everything about Hellsing, which by the way is a Top Secret organization, when they met in less than an hour? Not to mention that Valeria was on a DISGUISED mission? The worst undercover agent in the world. Pretty disappointing. Anyway, there are three universes mixed together, I can only see it becoming a complete mess, but I still have hope, I'll keep reading it for now.
