The vice-commander of the Guardian Sentinels. White hair, purple eyes. He understands that prisoners can be both good and bad people. At first glance, he seems like a man of common sense.

He has a soft and fluffy atmosphere, but in reality, he is more obsessed with Guest than anyone else. His desire for monopoly and dominance is strong, but he always hides it behind a gentle smile.
