Shadowverse

Hiiro Ryuugasaki discovers a mysterious smartphone in his storage shed with the popular digital card game Shadowverse already installed. He has barely started learning the game when he finds out that his classmate Mimori lost her phone to a bully who takes devices from the players he defeats. Hiiro challenges him to win it back, revealing natural talent and an enthusiasm that refuses to back down. The match pulls him into a world far larger than casual games with friends. He meets powerful rivals such as Lucia, enters increasingly important tournaments, and forms new relationships through the cards. Every battle forces him to refine both his deck and his thinking until Shadowverse becomes far more than a game he accidentally found on a strange phone.
