My favourite Bleach song is the eleventh opening: Anima Rossa by Porno Graffiti. My sister, who is a big fan of Bleach, says it's a male who sings it. I, who is only on episode 86, believes it is a female. It just sounds like one.
Despite the song sounding as though a female sings it, I too have reasons to believe it is sung by a male. My reason is because, I remember noticing that Fullmetal Alchemist's (2003 series; not Brotherhood) first opening theme-Melissa- is also by Porno Graffiti... but the singer is audibly male. You can just tell. Although, I don't want to believe a MALE sings Anima Rossa.
I need to know, because I imagine certain characters singing my favourite anime songs (but the character has to be from the same anime as the song :P ), and I imagined Rangiku singing it. I have no idea why; I just did (and still do). But if it's a male who sings it... I have to change that.
I'd appreciate it if you could give me unquestionable evidence.
