The PS Vita/3DS JRPG Conception II is based on a slightly weird concept. The protagonist must raise his affection with a variety of girls in order to generate a number of “star child” and lead them to battle. No, he doesn’t do it in the usual way. While it skims the border quite closely Conception II isn’t an eroge.
Today Spike Chunsoft released the opening video of the game and announced the preorder bonus.
