Profile:

One Fourty Nine, whose name reflects the goroawase for "Hiyoko" with the number 149, is a blonde man who appears youthful and vigorous due to government experiments that de-aged him. Originally an elderly gentleman in his eighties, he was subject 149 in a secretive program that reversed his physical age. Despite his youthful appearance, his mind carries the wisdom and memories of eight decades, though his personality has regressed to a childlike innocence and curiosity, creating a weird contrast. He is simply known as Piyo to his friends and peers.
