This puzzle takes the Adult constraints found in Parasitic Destruction and Romantic Destruction and turns it into a standalone constraint. Hopefully this serves as an intro and practice before tackling the other puzzles. The other parasite sudoku can be found here: Parasite Sudoku: Larvae.

The rules are as follows:

• Place the digits 1-9 once in every row, column, and region.
• Parasites: Draw parasites moving orthogonally through the grid that connect all circles that share the same digit. Parasites may not move diagonally, branch, or cross themselves nor each other, but they may touch themselves and each other otherwise. The start and end of each parasite must occur on distinct circles. Small white rectangles indicate cell borders crossed by a parasite or different parasites.
• All parasites in this puzzle are adults. Adults must contain a total number of bends between each circle (not counting bends on circles) equal to the digit in its circles. Additionally, all the digits an adult crosses are grouped by the regions they belong to, and the sum of all the digits in each group must be divisible by that adult's circle-digit.

The puzzle is available on SudokuPad and Penpa (answer check is on sudoku digits and parasites using the green line tool). Have fun solving!
