And so Kamui enrolled into an academy which utilizes a ranking system of which the top 5 combatants are granted voyage rights into Solcia. Kamui’s goal is to obtain a certain bell-like artifact, which does make its possessor King of Solcia - and even has the power to grant wishes. Using said artifact, Kamui wants to turn his little sister into a normal girl again. On the day of his enrollment, Kamui has to directly face his first opponent in a placement tournament during the school ceremony – to make matters worse, Kamui, the lowest-ranked freshman, has to face Kaguya, the current ace of the academy. A fantasy-battle light novel is about to begin.
