Shinobi, Koi Utsutsu is the latest project by Otomate and Idea Factory, with art by the same main artist for Nise no Chigiri. In it, the heroine will be getting to pursue some rather famous ninjas:
The tsundere type, Sarutobi Sasuke (CV: Terashima Takuma)
The cool type, Kirigakure Kuroudo (CV: Sakurai Takahiro)
The serious and taciturn type, Yuri Kamakiyo (CV: Ono Yuuki)
The know-it-all shota type, Garaiya (CV: Shimono Hiro)
The arrogant type, Anayama Daisuke (CV: Suzuki Tatsuhisa)
The ??? type, Sanada Yukikage (CV: Toriumi Kousuke)
All that is known so far is that the game is slated for 2014 release and they are planning on releasing related situation CDs, so the setup seems similar to that of the Diabolik Lovers franchise. The official website is here, though there is nothing there yet other than the announcement PV that was shown at Otomate Party 2013. The main image was scanned by k704; the character images are from the PV.
