Karmanami

KaruMana is the het ship between Karma Akabane and Manami Okuda from the Assassination Classroom fandom.

Canon
Karma and Manami are on good terms, and they are able to trust one another, getting along pretty well. Karma considers Manami the girl he can tell anything to, and it's implied that Manami thinks the same with him. When Karma is asked by a few classmates which girl he likes most, he says Manami, because he's interested in her abilities when it comes to science, mainly because they help him with his pranks.

Korosensei paired them together during the 'Test of courage' in the 'Island Arc' and he also said "I was shocked by Nagisa at that moment." In that moment Karma confided with Manami revealing to her his weakness point and she smiled to him, aware that Karma has shown her something that he hardly shows to others. Manami was scared of him, but now they have one of the most easygoing boy-girl relationship and, Okuda's calm, has managed to overcome Karma's distrust of other people.

Okuda during the 'Civil war' is in the faction that doesn't want to kill Korosensei, but during the direct confrontation between Karma and Nagisa she says "I want Karma-kun to win too !!" which implies that even when they're on opposites sites of an argument, Okuda still wants Karma to win. When Korosensei and the second god of death are fighting, Karma grabs Okuda and drags her out of danger and finally Okuda remembers the words Karma told her during the 'Test of courage' in the cave, because she thinks Karma may deserve to kill Korosensei. Seven years later they're holding hands at the station in chapter 179 and, in Karma's extra chapter, Karma says "You're so different from the small glasses-wearing person I like."

Fanon
Although they barely interact on screen, from the additional material, it's clear that these two interact a lot outside of Class 3E. This ship is in a sort of ship-war with the ship Karmagisa, hence why it is rather unpopular
