Normal 6x6 sudoku rules apply; i.e. fill every cell with a digit from 1-6 such that a digit does not repeat in a row, column or 3x2 box.
Yin Yang: Shade every cell one of two colours such that each colour forms a single orthogonally connected area and no 2x2 area is entirely one colour.
Little Killer: Clues outside the grid show the sum of the digits in the first continuous run of same-coloured cells along marked diagonals.
Torus: The grid is toroidal; i.e. each edge of the grid is considered to be adjacent to its opposite edge. For example, the 2nd cell pointed at by the 22 Little Killer clue is r2c1.
Solution code: Monochrome digit(s) - i.e. digit(s) that appear in only one colour - in ascending order

Absolutely delightful puzzle! I've been playing around with yin yangs in strange spaces, and it was really fun to see your (very elegant) take on the same problems I've been chewing on. 10/10, thanks for setting!

Is this the first yin yang puzzle with the tororidal rule ever?

Finishing the yin yang was the hardest part. Including the infinity clue was a great way to clarify the rules, and justify toroidal geometry. I published an infinite tiling sudoku a few years ago if you are interested, "Tiling Pentomino Sandwich Sudoku."

If the concept of an "angry upvote" were given human form, it would be ThePedallingPianist.

Really cool puzzle that challenges everything you thought you knew. The rules work very well together. Thank you!

A great puzzle! It was super cool to have to unlearn and relearn all of yin yang. Thanks for providing the outside grid and for setting :)

does the toroidal restriction also apply to the yin-yang coloring?

TPP: Yes that's right! I know I probably ought to have expressly clarified that in the rules, but I figured it becomes obvious pretty early on in the solve that it must apply :)
