Links to the previous parts of the series are given after the rules.
Rules:
Normal Sudoku rules apply. Place the digits 1-9 once in every row, column and 3x3 box.
Nonogram: The numbers outside the grid define a nonogram. Shade the cells in the grid so that the pattern of shaded cells matches the numbers given for each row and column. See the example of a solved nonogram below. A digit in a shaded cell must see the same digit a king’s move away at least once. All shaded cells are given; that is, a negative constraint applies.
Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.
XV: Cells separated by a V sum to 5; cells separated by an X sum to 10. Not all Vs and Xs are necessarily given.
Region sum lines: Digits along a blue lines have the same sum within each box the line passes through.

This is excellent, like three puzzles in one. I really enjoyed peeling away the layers.
