Another Murder Mystery: How Could I not Feature this Sudoku?

Today's Puzzle:

As I mentioned in the introduction, a Sudoku that's all about murder mystery must surely be featured on a channel named Sudoku Sleuth. I found this much tougher than the implied 1* rating however, as you may be able to guess from the video length.

Please let me know in the comments if I should feature the original too!

Rules:

Sherdoku Holmes we need you again! A new numeral killer is on the loose and we need your help to solve who the killer is.

Place all the digits 0-9 in each row, column, and box but one digit in each was murdered and will not fit. The victims vary and can even be the same value as the killer.

Box 1 The Library - German Whispers: adjacent digits must be at least 5 apart.

Box 3 Pool Room - Quadruples: digits in the small circle must appear in one of the surrounding cells.

Box 5 Game Room - Arrows: Digits along the arrow must add up to the digit in the attached circle.

Box 7 The Office - XV: Digits separated by a X must add to 10, and digits separated by a V must add to 5.

Box 9 The Gym - Renban: Digits along the purple lines are consecutive in some order.

Box 2,4,6,8 Hallways - Odd/Even and Palindrome: Digits in a circle must be odd, digits in a box must be even, and digits along the grey line read the same forward and backwards. For this puzzle 0 is considered even.

Secrect Passages - Little Killer: digits along the indicated diagonal add to the value provided.

As before, you will find one last cell where the killer takes his last victim, know this: the killer left a note saying “There is nothing to be added to my life therefore I kill those who can take from me.”
