Kaeru no Tame ni Kane wa Naru

In a land far away, the two princes—Richard (of the Custard Kingdom) and the game's main protagonist (prince of the Sablé Kingdom)—have shared a friendly rivalry since they were small children. They often compete, although it usually ends in a tie or close win. In Fencing however, Prince Richard is always the victor.

One day a messenger arrives from a small neighboring kingdom, warning the princes that the evil King Delarin has invaded the Mille-Feuille Kingdom and captured the beautiful princess Tiramisu. In yet another boastful attempt to best the Sablé Prince, Richard grabs a boat and rushes towards the kingdom.
