Yuu Mononobe

Yuu Mononobe stands as the only male in existence capable of harnessing the power of a 'D.' Once a highly trained operative within the covert special forces unit Niflheim, he was reassigned to the all-female Midgard Academy under special orders. Concealing his military background to blend into student life, he reunites with his long-separated sister while forging bonds with his classmates. Yet when colossal dragons threaten their world, Yuu steps forward without hesitation, channeling an ironclad resolve to shield everyone he holds dear.
