Ayame's Great-Grandchild
He runs "Mysterious Wares Shop Akatsuki," which he inherited as Ayame's great-grandchild from her previous life. The guy's basically the neighborhood fixture—always got a smile on his face, genuinely warm and kind to everyone around him. The local kids have nicknamed him the "Smiley Man" because of it, and honestly, he's beloved by pretty much all of them.
What sets him apart is a particular condition that gives him unusually sharp perception of his surroundings. It's something that comes up pretty naturally in how he moves through the world.
He and Ramune go way back—they've known each other since childhood and consider themselves brothers at this point. That bond clearly runs deep.
