Sozaya is an anagusi man from Kesizma working as their main diplomat in Valtshora during and after the Rigasia/Kesizma War.

He's described as a very well-built dude with an impressive moustache and a packed dad body, usually carrying an elaborate sword.

He seems to be quite the patient person and a source of esoteric knowledge for both Claire Dubois and Gaia Dynko.

Apart from his basic skill as a dreamwalker, he does have access to the power granted by the Umichooan Subtle Machine, that he was granted as a boon for helping Umichoo getting rid of a rogue gifted that had set himself as god in a far away timeline.
