In 2025, the social game Crown Hearts about the battle between the princes' country ‘Stella Crown’ and the princesses’ country ‘Floris Hearts’ was a smash hit, and pro gamers have become as popular as star athletes. Koharu attends Luminus Academy with his pure osananajimi and hopeful new pro gamer Maher, kind and slightly brocon imouto Hiyoko, and Hiyoko’s friend and extremely popular net idol Ayane.
One day, they attended the opening ceremony of the annual Crown Hearts event “Divine Crown Battle”. However, this year, they announced the new “Crown Hearts VR”, where one may battle others in the real world using the latest in virtual reality technology. Sixteen entrants were chosen for the “Divine Crown Battle VR” tournament: a ‘king’ and his seven ‘flower princesses’, and a ‘queen’ and her seven ‘star princes’.
Koharu was chosen as the king by the AI girl Polina, who appeared out from the Crown Hearts world. He must battle in the tournament alongside the sword princess Maher, love princess Hinako and many others. It was rumoured that the winner would have his or her wish granted. Are you ready for this new generation battle royale!?
