Fantastic. Only 3 episodes but they fully deliver. Even more if you're already a massive bleach fan as you can see some parallels.

I watched some movie or ova type thing from it and at the end it shows a building that says soul society London or something and it shows the title but parts of it burn away just leaving the letters that spell bleach

Watched it English dubbed, the voice acting gave a sour impression on me. Shame, really. It should have fit the London setting like a glove.

or piper like guns
