A former warrior, once known as the "strongest" of the Quasi Braves (exceeding in techniques), he was petrified/frozen 526 years ago, before the seventeen beasts appeared and least than a year before humanity went extinct.

He is the last human known to be alive 527 years after humanity went extinct. He was stone-frozen a year before it, under the age of 16. His resting-curses was lifted two years before the events take place.

He likes to play with kids (after growing up at an orphanage), although some mistake it for "him being into little girls."

Later in the anime, he falls in love with Chtholly and proposes to her; she accepts.
