Katekyō Hitman Reborn! Fate of Heat is an RPG based on the Kokuyo and Varia Arc of the manga series; however, it is told in a different perspective. Two new characters designed by the author of the manga series make their appearance in this game. These two new characters, Albito and Rizona, from the Evocatore Famiglia, are intricately related to the existing characters from the Kokuyo and Varia Arcs.
