Fourth year high school student Naniko Fueki is just a normal 18 year old teen. That is untill he meets Sueki Nasha and his world changes. Sueki Nasha is a new transfer student @ Asuna regional high school (the same high school as Naniko), who has some big secrets and lives in a different world than Naniko. Unfortunately for him he gets dragged into this world and has to try to survive.
