Nippon Ichi Software has revealed a new Vita game, titled "Hotaru no Nikki," otherwise known as "Firefly's Diary." Evidently it'll be an action title, and you'll control a firefly with the intention of helping a young girl named Mion.
Locations seem to include ruins, and enemies seem to be of the shadow variety -- if you ask me, this sounds a lot like Ico, which is just fine by me. In Japan it will launch with a collector's edition that comes with badges, a soundtrack, and an art book, and there will also be a PSN download.
No word on a western release yet.
