I couldn't get into Get Backers but Ban is voiced by my all time favourite, Canna Nobutoshi! I. Love. That. Man. *^_^*

Though I enjoyed Spiral until the last few episodes...I wish they would wait for the manga to be complete before attempting a series. O_o Rather than pulling a Berserk they made up they're own ending for Spiral and it didn't work for me. *sigh*
