Korekiyo x Seesaw

Korekiyo x Seesaw is the cargo ship between Korekiyo Shinguji and a seesaw from the Danganronpa fandom.

Canon
Korekiyo used a "seesaw effect" by jumping on a loose floorboard in order to impale a hidden under a cage Tenko Chabashira on a knife.

Fanon
As a result of the trick mentioned above, combined with Korekiyo's character being a foundation of memes, as well as the fact that he got greedy for another kill (due to his goal of making 100 friends for his Sister), even though he would have been uncaught due to lack of proper final evidence had he stopped at his first murder, some fans jokingly ship him with seesaws. They say that he got greedy for another kill because he didn't want the trick that he prepared go to waste as well as because of his love for seesaws.
