Requiem, Vampire Knight

I've long wanted to work out what's out there to collect (in English) relating to the Pat Mills and Olivier Ledroit series "Requiem Vampire Knight". Here's what I've found so far. Further examples of other books in the series welcome.

You get 2 stories in each of the five 'single volumes' - so that's 10 stories in total. 

The two omnibus volumes collect 5 stories each - so that's 10 stories in total.

Requiem Vampire Knight, volume 1 - Resurrection & Danse macabre

Requiem Vampire Knight, volume 2 - Dracula & The vampire ball

Requiem Vampire Knight, volume 3 - Dragon blitz & Hellfire club

Requiem Vampire Knight, volume 4 -  Convent of the Blood Sisters & Queen of Dead Souls

Requiem Vampire Knight, volume 5 -  The city of pirates & Blood bath
