The world of shipping is a wild one. People love everything from the canon romances to pairings that are totally off the wall. Some weird anime ships are fun ones - it's hard not to laugh at the idea of Haruka Nanase from Free! being more interested in wooing water than any of his friends. But others easily qualify as the worst anime ships - believe it or not, there are people out there who ship Myne and Naofumi from Rising of the Shield Hero!
If you're a fan of one of these pairings, no personal offense is meant. Lots of awesome people like pairings that are weird or even awful, and everyone has a different take on what counts. That said, these pairings are definitely eyebrow-raising.
