Despite the manga being popular in Japan with 23 Million copies sold and having an anime by a studio like Production IG, the manga still isn't officially translated in english. Ao Ashi has an official release for french and spanish speaking countries but not english which is a very large portion of it's western fanbase. Now that we know the manga will have 40 volumes, i ask VIZ Media to please release the manga in 2-in-1s omnibus format.
