All five of my games that belong to the BatLive series!
Each game focuses on a specific unit, shown on the cover art. It's recommended that you play through the games in order to see how the characters (and art) grow, and also to spot references I make to past games. Each game is about an hour or so long so they shouldn't take too long to play.
Battle Live: Focuses on Ayane and Akiomi
Halloween Live: Focuses on Black Widow and Ace of Spades
Christmas Live: Focuses on Joker Game and Saturn Ring
Valentines Live: Focuses on Neapolitan
White Day Live: Focuses on Kagura's Song
