Hello.

Normal sudoku rules apply.

Digits are grouped into modular sets:

1mod 3 → {1, 4, 7}
2mod 3 → {2, 5, 8}
0mod 3 → {3, 6, 9}

Cells with the same relative box positions must come from the same modular set. For example if the first cell of box 1 contained a 5, every first cell of each box must contain digits that come from 2,5 or 8.

Region borders divide blue lines into segments of the same sum. This sum can be different for different lines.

Digits do not repeat along the indicated diagonal.

Digits along a pink renban line form a set of consecutive digits in any order.

Have fun.
