Nothing Remains

This puzzle was inspired by a Mr. Menace puzzle from a while back. Originally this puzzle was posted in a more casual setting, but I liked this one so much I decided to share it here too. Enjoy!

Rules:

Normal Sudoku rules apply.

Little Killer: Clues outside the grid give the sum of the digits along the indicated diagonal.

Renban: Digits on a line form a set of non-repeating consecutive digits in any order.
