Meh, one of the first titles I downloaded for Kindle was
Love Neco, and I also bought the first two volumes of
Earthian a few days ago.
Chances are the BL will keep on racking up if emanga remains one of the only sites to cater to the UK market, since they don't offer much else.
As for those you've suggested:
Bloody Monday - Available for Kindle on Amazon. PERFECT.
Lucifer and the Biscuit Hammer - Seven Seas just got that.
High School Debut - Viz have it, but it's region restricted.
I might treat such titles in the same way I treat R1 licensed anime and download it anyway, but the fact I could just buy it in print will weigh heavily on my mind...
Magico - One for the scanlation list, cheers!
Monochrome Factor - License died with Tokyopop, followed by JManga, so all's good.
Nineteen, Twenty-One - This one's short, sounds interesting though. Plus I need to check out more Manhwa.
Prunus Girl - Ah yes, this was very much on my radar already...
Rurouni Kenshin - Also available on Kindle! Loved the anime, so this will now be high on my list.
Many thanks!
