This puzzle was created by Jakhob and wooferzfg, and it is a variant of U-Bahn. It is named after a fighting duo in Paper Mario: The Thousand-Year Door.
If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.
Draw two separate loop networks through the centers of some cells, which may not intersect each other. Each loop network may branch or turn, but may not have any dead ends.
Clues on the top and left apply to the first loop network, and clues on the bottom and right apply to the second loop network. A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.
Lösungscode: For each column except the last, from left to right, the number of lines (for both loop networks combined) leading to the right from that column

Great puzzle! I'm with Christounet--I found the left side a lot harder than the break-in. But the whole thing was lots of fun.

Beautiful ! The break-in is very clever and wasn't the hardest part for me surprisingly. Resolving the left part was what stalled me a bit here. Awesome idea ! Always love your U-Bahn variations. Thanks :)

80 minutes! I didn't read the guide before attempting, which turns out would have been pretty helpful (I spent 30 minutes to work out "each cross starts a segment in its row and column"...). Possibly a 3-starer for people already familiar with the genre.

@Piatato Maybe I missed something more straightforward then, I’ll have to revisit perhaps.. There was no intention to scare!!

Great puzzle! I expected a different break-in, this was surprisingly straight-forward to me and not more than a 4*. Very clever and the logic felt fresh as there were things that at least for me were new to discover. Thanks!

Great puzzle! @KNT why are you scaring people, haha! The break-in felt completely logical and fair to me. :-)

Good idea and very well executed, thanks!

I also want to add that the guide is fantastic, and even if people aren't going to solve the puzzle, they should definitely take a look at that.

Definitely a very hard break in. One has to juggle a lot of information in a way that isn't so easily notate-able. But after the initial hurdle, the puzzle is fairly smooth and straightforward. So, difficulty is hard to say: 5 stars for opening, 3-4 stars for the rest? Overall, always a pleasure to solve these :)

I listed this puzzle as 5 stars for difficulty because some steps are very tricky. However, it is a relatively short puzzle, so it might be a quick solve.
Also, thanks to the_cogito for creating the puzzle that inspired this one :)
