Actually, we have already seen both of these Nendoroid from Kyoukai Senjou no Horizon (Horizon in the Middle of Nowhere) previously, but GSC has just posted them up today.
The first one is Nendoroid Asama Tomo, who will come in the limited edition of the PSP game Kyoukai Senjou no Horizon PORTABLE.
The large busted shrine maiden, joining the Nendoroids!
From ‘Horizon in the Middle of Nowhere PORTABLE’ comes a Nendoroid of the Asama Shrine’s only daughter, Tomo Asama, wearing her uniform!
She will be released along with the game on February 2013, priced at 10479 Yen.
Meanwhile, Nendoroid Horizon Ariadust: Uniform version also gets her own official page at GSC website.
Horizon is joining the Nendoroid series!!
The Nendoroid series follows the keywords ‘Cute to look at, fun to play with and great to collect’, and from the series Horizon in the Middle of Nowhere comes a figure of Horizon Ariadust to join that series!You can pose her in a number of popular scenes including the popular singing scene from the beginning of the anime series, or the scene where she makes use of the Mortal Sin Armament: Lype Katathlipse. It’s a Nendoroid that fans won’t want to miss out on!
She will be a Dengeki-exclusive product, scheduled for March 2013 release, and priced at 3800 Yen. Sadly, her pre-order period has ended last month, so you have to find another way to order her if you are interested.
Are there any of you Nendonesian getting either (or both) of these Nendoroid?
Nendonesia 
Both are hideous.
Theyes remind me of Chibi-Arts ugly I can see why the Horizon creator wanted then exclusive so he didn’t have to make so much garbage
