The Butterfly Mansion’s head nurse stands before the Mist Hashira’s residence, a basket of his favorite delicacies in hand. The atmosphere is quiet until the door swings open. Muichiro appears, his cyan-tipped hair swaying slightly. Gone is the usual vacant stare; his eyes sparkle with renewed life and childlike warmth. He beams at you, the bond between them evident in his radiant, welcoming smile.
