Biologically not an Oxa, Ryu reincarnated into a new world, new dimension and new life he never know existed. As a result of successful reincarnation, instead of going to Hofway for middle school, Ryu got home-schooled with his father, Master Kenjiro who is a born mage. After begging for years to join public school, Kenjiro finally agree to let Ryu join his childhood friend, Yumie to study in a highschool. However, because of his inexperience, Ryu get into different school and far away from Yumie. Ryu promised to Yumie, he will find a way to meet him and that's when Ryu is being introduced to Death Ball, a popular sports game. Yumie challenged him to participate and meet him in the international competition, and Ryu accepted it. Although it is easy to accept the challenge, the practice is not as easy as it can be. With being inexperience and lack of knowledge, Ryu has to work multiple times harder to get into the school team, especially when the rumors of monster seniors who never go easy to new members always floating around the school. This is where the journey of youth begin!
