Conception II: Children of the Seven Stars

Conception II: Children of the Seven Stars is a Japanese role-playing video game and a follow-up to Conception: Ore no Kodomo o Undekure!. The player control a student at a high school that doubles as a training facility for demon hunters. The protagonist possesses an extremely high amount of ether in his body, which allows him to conceive Star Children to fight demons by "classmating" with his other classmates. During battle, fighters can be strategically placed around the enemies, allowing players to either safely target weak points or charge head on for bigger rewards.

Wake Archus is a teenage boy living in a world plagued by demonic monsters that pour out of mysterious rifts called Dusk Circles. After a monster attack claims his sister's life, Wake discovers the mark of the Star God on his hand and enrolls at an academy that trains marked youths to fight the threat. Blessed with an unusually high amount of ether, he becomes known as "God's Gift," able to venture deep into the monsters' labyrinths and to create powerful allies called Star Children by bonding with the academy's most gifted young women. As he battles through the Dusk Circles alongside his classmates, Wake forms deep connections with them while uncovering the darker forces behind the monster outbreaks.
