This puzzle was made in collaboration with lifeless for the CTC discord October Monthly Prompt "Into the Woods". It's also the first puzzle I've published, so feedback is helpful and welcome.

RULES:

Normal Sudoku rules apply.

Tree(3): Draw a line that goes through cells on the grid and doesn’t touch itself orthogonally, but branches at one point into 3 separate line segments. (It starts as a regular line, but splits into 3 branches at one cell). The line must start from the given 3 in r9c5, and each branch must end in one of the 3 given green diamonds (in r1c5, r2c9, and r3c1). No matter the digit, the value of every consecutive cell along the line starting from the 3 in r9c5 is given by the ruler function multiplied by 3. (The ruler function is a sequence going 1 2 1 3 1 2 1 4 1 2 1 3 1 2 1 5 …, multiplied by 3, that means starting from the 3, consecutive digits on the line have the values 3 6 3 9 3 6 3 12 3 6 3 9 3 6 3 15… If you are still confused, I would search it up).

Digits on the line, with the exception of the cell at which the line branches, must be either a FACTOR or MULTIPLE of their value. E.g a cell on the line with value 6 can be 1, 2, 3, or 6, and a cell with value 3 can be 1, 3, 6, or 9. The digit in the point that the line branches can be anything (standard sudoku rules still apply).

Blue Japanese sums: Blue clues outside the grid give the sum of the consecutive values on the Tree(3) line. A ? indicates any one digit 0-9, and a ? in the tens place of a clue cannot be a 0. A * indicates any number of clues, including 0, of any sum.

Red Japanese sums: Red clues outside the grid give the sum of consecutive digits on the Tree(3) line. A ? indicates any one digit 0-9, and a ? in the tens place of a clue cannot be a 0. A * indicates any number of clues, including 0, of any sum.

Red and Blue Japanese Sum clues can, but don't necessarily, point to the same consecutive string of digits on the line.

3-Kropki: Digits AND/OR values separated by a purple dot have either a difference of 3 or are in a 1:3 ratio. The value of a cell not on the line is its digit.

P.S. Extremely sorry about the shape of the finished line, it came up a bit too late in the making process and all my attempts to try and change it failed.
