- All four characters are considered 'Monsters' on the court but are actually sweet and funny people who care so much about their loved ones.
A look into the lives (past, present and future) of a monster generation tennis team. They're powerful on the court but fun and ridiculous when they're not in the middle of a match. Two of them have known each other since they were kids and the other two have been friendly rivals since middle school. They all become good friends in high school and are feared by others because they make up such a strong tennis team.
