Soyuz (ソユーズ Soyūzu) is a member of Ishigami Village and the long-lost son of the leader of Petrification Kingdom.



Soyuz is a bald man with large, round eyes and a distinct cross-shaped scar on top of his head. He is shirtless, wears a large shield on his back held by a rope strap that is slung around his shoulder, and baggy pants that reach only past his knees.


Soyuz is a quiet and reserved man living in Ishigami VIllage. He is rather shy when it comes to women, incapable of resisting the charms of Amaryllis, and becoming incredibly flustered around Kohaku when she changes.
