(He had made the smart decision to abandon Kanto long before it became an issue, and he had only returned in the last year or so. He still remembers the first newspaper he found abroad with the news.)
The mirror shines smartly, so wonderfully cared for by those who held it in great esteem, and he's almost nervous to peer into it.
The face looking back at him holds a dangling water balloon in one hand and is wearing a Dratini mask (because of course it is.) It can't be more than eleven or twelve, judging by the way the yukata is tucked around the knees to show the shorts beneath it.
It just looks at him quietly, considering, before it sways the balloon in place to show the Horsea on the side of it.
It reminds him, quietly, of leaving home - and it draws his eye away from the mirror and to the mountains beyond Mahogany Town, where his father sits and waits.
When he looks back, the other is gone, echoed in the way a boy skips after his mother nearby. When Hassel looks, the lad is holding a swaying balloon in one hand, the determined face of a Horsea looking back at him.
