Look at the sword in CC. Look at the sword in CT. What is the difference between the sword in these two games? In CC, it makes people go in murderous rampages. In CT, its a holy sword used to fight Lavos. What would make this huge reversal? Masa & Mune being asleep, and the Sword massacring tons of people, becoming a cursed blade. According to Aura, in Japanese lore, if a sword is not washed after being soked in blood, the sword drinks the blood, and becomes cursed. The PSX ending, with a bloody Masamune, implies thats probably what happend.
