Miyako Kashiwa

It was just a usual morning. Akira Shiroyanagi, a high schooler who loves games and konpeito (a Japanese sugar candy), is suddenly dragged into a battlefield by a mysterious girl who calls herself Mion. The participants are told that they are "erased from the family register, involved in an experiment, and have gained certain powers." Akira is determined to win the game with his newfound powers and destroy the organization.

"Hey, you said you wanted a little sister, right?" Highschool freshman, Toujo Basara, was suddenly asked by his father and fell into a state of panic. On top of that, the eccentric father told him he would be getting remarried. He then departed overseas after bringing Basara two beautiful step-sisters. Things aren't as they seem in this series, as Basara discovers that his new "family" has a few secrets he's yet to unveil. Adaptation of the Light Novel series written by Uesu Tetsuto and with illustrations by Ookuma Nekosuke.
