Granzella is a home to many former Irem employees including Disaster Report and Steambot Chronicles creator Kazuma Kujo. Since opening the Ishikawa based studio has mostly made PlayStation Home items like the Glittering Sands Beach (pictured) and oddities like virtual contact lenses.
But, it sounds like Granzella might be making PlayStation Vita games or at least Vita software. Two titles popped up from Granzella from Japanese magazine leaks, Mangakakeeru which might be related to manga artists and Ava Tabi.
No details on either other than a trademark we saw for Ava Tabi, maybe that’s a portmanteau of "avatar" and "tabi" for trip? The other game might be related to comic artists or as they’re known in Japan, mangaka.
