Ex

Ex is a legendary holy sword endowed with independent consciousness, handed down across generations within the royal army. In ages past, he fought alongside celebrated knights of each era, accumulating a storied record of distinguished deeds. He now finds himself confined in the demon king's prison together with the princess. Though he once held an unwavering belief in the princess's noble character, repeated firsthand witness of her caving to food-based 'interrogation' tactics and readily divulging secrets has gradually transformed him into a watchdog and commentator of her failings—leaving him profoundly disillusioned by her chronic lack of self-restraint.
