There is a certain mad and twisted warden who enslaves peoples' souls and plays with them, is an arch-nemesis to a heroic fighter who wields relic guns, is the thing under the bed, and on top of it all, he is a support. I mean, when a support is like that, I think their backgrounds don't matter.

I agree, there aren't many support champions in League and a new one would be very welcome. Besides, they stated "Ao Shin embodies this elemental duality, capable of raining good fortune on his allies and, in the very next breath, bringing stormy, thunderous ruin upon his foes." Sounds supportish enough to me.
