I thought it sounded like Tomaru too! Though part of that might just be because I’ve been listening to the Mai-Hime soundtrack a lot recently. But, still, her voice a certain quality to it that makes me think it’s her.
The song is alright, but I want to hear some woodwinds soon! Or brass. And, heck, Noir had plenty of Accordian and Pipes and I want those too! (I’m sorry, strings, I love you a lot but I also love variety.)
