VERTEX FORCE - S01

Akira Toudou is a high schooler living in northern Okinawa, living peacefully with his mother and his older sister, Haruka. But behind that peaceful life is a secret passed down through their family: Haruka inherited a mysterious power from their father, known only as "Engine," and has spent her life hiding it from others. Akira, though, inherited nothing. He carries an inferiority complex because of his own weakness. Then strange events started happening all over the world. What is the goal of the unknown enemy closing in on Akira and his friends? Now, with the fate of the universe on the line, a brother who has nothing and a sister who has everything must discover what they can truly do together.
