Hizaki Mikado was the best combination of sweet, wise, and badass grandma. Knowing the flags raised in the story, it didn't take away the weight of the inevitable fate in the narrative. But the most touching thing was the evident hope she placed on Ushio and the happiness of having that hope after centuries of fighting. The soundtrack that accompanied didn't need to go that hard but it did. All the while Kirio acts and talks like a brat that he is who has zero respect on anything and Kuin is an absolute edgelord - whether he'd be a one-dimensional foil or a future ally is still up in the air. If Kirio doesn't cry like a baby in his arc, I'm gonna be mad.
