Return of the Acolyte

Synopsis

Aika Tendou has given up Vanguard to protect his younger sister Rino, whose overwhelming imagination once made a cardfight feel real—and left her unconscious for a week. Their quiet life is shaken by transfer student Sekai Mase, who seems mysteriously connected to Rino and her paintings. This manga is based on a fan-submitted storyboard from Monthly Bushiroad's Vanguard Manga Award contest.
