Van is the strongest assassin, feared by all magicians. He serves his best friend, the prince, and has defeated countless magicians. Before long, this man was hailed as "the strongest"... but in fact, he possesses no magical powers. With his accumulated magical knowledge and special combat techniques that don't use magical powers, Van wins the long battle for the throne. It's all to make his best friend the prince king and protect his race, the only race in the world that lacks magical powers and is persecuted. But at the end of the battle, what awaits Van is... his best friend's betrayal. His family is killed, and Van is left with no choice but to wake up 10 years into his life. His second life will not be the same. The path Van chose... was to "rise to the top of the magic academy without magical powers."
