After seeing Christounet's mirrored digits constraint on CTC, it felt like an idea that belonged in a Yin Yang hybrid puzzle. So, I made one.

Normal sudoku rules apply.

Yin Yang: Shade some cells in the grid such that all shaded cells form an orthogonally connected region, all unshaded cells form an orthogonally connected region, and no 2x2 square is either fully shaded or unshaded.

Mirror Cells: For the purpose of non-sudoku constraints, digits in shaded cells have a value mirrored on the range 1-9. (So, a 1 acts as a 9, a 2 acts as an 8, and so on.)

Kropki Pairs: Cells connected by a white dot have consecutive values. Cells connected by a black dot have values in a ratio of 1:2. Not all possible dots are necessarily given.
