Gensagi

Gensagi is the slash ship between Murakami Gennosuke and Miyamoto Usagi from the Usagi Yojimbo and Teenage Mutant Ninja Turtles fandom.

The Big Brawl
Usagi is finding his place at the Battle Nexus when he passes. He pauses and says that he's surprised to see him there and Gen asks why that is. Usagi says that he didn't think contests of honor were something Gen was interested in, and Gen laughs at that. He's not there for honor, but had placed a huge wager on himself to win, which upsets Usagi. He offers to get Usagi in on the action, but Usagi turns him down and wishes him luck. He then turns back and jokingly changes his wish of luck to a wish of fortune in Gen's case. He comments that Gen will never change, and Gen asks why he would when he's already perfect.

The Real World
Usagi, Leo and Gen reach a river that will take them to the Shogun's palace. Gen says that it's a shortcut and Usagi says that Gen's shortcut's will be the end of them. He suggests that they head back when they are suddenly surrounded by ninja. They fight them off, Usagi and Gen fighting side by side. Gen asks whose idea it was to come this way anyways, and Usagi angrily reminds him that the shortcut was Gen's idea. The ninja are the called to retreat, confusing Usagi, but Gen just says that they're being cowards. They are then fired upon by the ninja, and Usagi says that there's only one way out. He indicates the river and Gen asks if he's joking. Gen says that he hates water, but Usagi just pushes him in the river and jumps in after him.

Usagi then pulls Gen out of the river, and says that the ninja won't give up so easily. Gen exasperated asks if he thought that was easy, when an arrow with a note is shot at them.

Fanon
Gensagi is a smaller pairing within the Usagi Yojimbo fandom. Mostly due to there already being many implied love interests for Usagi in the comics, and the very popular fanon pairing of him and Leo.
