I enjoyed Phantom of the Inferno visual novel, it has nice writing despite slow pacing and gun obsession went with it.

However, I have jarring memories of Demonbane anime (shame, I seen the game story and it looks decent) and equally godawful Phantom of the Inferno OVA ( it is a serious waste of time).

Fate Zero is great stuff thanks to tight writing from same scenarist from Nitroplus.

But this project raised 1 BIG red flag for me, namely Gonzo. I liked some Gonzo project like Last EXILE but most of their production is not exactly high brow for me.

Will look at it with great trepidation, that's for sure.
