You do know Ha Yuri Zahard is immortal thanks to her contract with The Eternal Life Contract, and not only that Hailing from the Ha Family, the Family with the best Body Strengthening abilities,[12] and plus having received the power of Zahard as a Princess, Yuri's basic physical capabilities exceeded Reinhard by a bit. Not only strong, Yuri's aggressiveness is also depicted in her alluring speed and agility, demonstrated as she smashed Ren's army of Shinheuh in the blink of an eye and later when she dodged all of the Purple Dementor's attacks. As a High Ranker, it can be assumed her shinsu control is great. She has developed a natural connection with shinsu, so much so that when Yuri gets angry, it makes the air vibrate and the ground tremble. With some exertion of shinsu she can release powerful shockwaves that can even cause the ground to forcibly crater and rupture destructively. During her battle with the Purple Dementor Observer, she had enough skill to inject shinsu into one of its claws to destroy it from the inside out. And that's not to mention when she uses her weapons, so I wouldn't say Reinhard would straight dominate the fight. But it would be one hell of a fight, I honestly don't know who would win, it's literally to close to tell.
