A slightly bizarre pairing from the Togainu no Chi games, though, nonetheless totally viable. This pairing is based off the Executioner Bad End where Akira is raped and 'murdered' by Gunji. Though, for those of us who prefer to see the sunny-side of everything; Gunji merely knocked Akira out and took him back to the Castle for fun times. :D
Akira: The protagonist of the story and our uke. Akira is strong willed and quick to deny anything that could be seen as embarrassing, which makes him the perfect uke without being extremely girly.
Gunji: One of the antagonists, he's violent, childish, and probably completely insane. Yet, Gunji is adorable in every way. Despite, his childish ways, Gunji is incredibly strong (He is a Punisher after all), therefore, he tops Akira.
