Naito Mudano

Naito Mudano serves as an instructor at Rasetsu Academy's Kyoto campus and once held the title of the youngest combat unit leader in the Oni Agency's history. He adheres to a philosophy of eliminating all unnecessary waste, even going so far as to wear roller skates for the sake of efficiency. Though his teaching methods are harsh and his expression rarely softens, his true intention is to equip students with the genuine strength needed to survive the brutal conflict against 'Momotaro.' A man of both formidable power and deep loyalty, he stands as the pivotal mentor behind protagonist Shiki Ichinose's growth.
