Kannko

Kannko is the femslash ship between Kanna Kamui and Riko Saikawa from the Miss Kobayashi's Dragon Maid fandom.

Canon
Riko is Kanna's human friend and classmate. They spend plenty of time together outside of school and would often pick each other for partners during school activities. The first time Kanna was invited to Riko's house to play, Kanna declares that she wishes to pursue a similar relationship to Tohru and Kobayashi's with Riko, hinting at a possible romantic affection towards the human girl. Kanna desires to be closer to Riko. Kanna refers to Riko as 'Saikawa' because when the other kids at her school introduced Kanna to Riko as Saikawa, she naturally took up this name for her and started calling her it. On christmas, Kanna has rode on Riko while wearing a Santa's outfit.

Riko also stated that she likes Kanna a lot and would love to marry her. Additionally to this, Riko always blushes heavily when Kanna is close to her or when she compliments her, sometimes there is even a heart in her mouth when she blushes towards Kanna. However, unlike Riko, Kanna makes it more ambiguously, if she has romantic feelings for her, although she has stated on multiple occasions that she "likes" her, it's not known if this 'like' is meant in a romantic way.

In the spin-off manga, Miss Kobayashi's Dragon Maid: Kanna's Daily Life Riko and Kanna appear in almost every chapter together. Riko also continues to be very obviously romantic interested in Kanna, often blushing around her or calling her cute. One time when the two accidentally fall in a rather 'uncomfortable' position, Riko has said that she likes a "wild" Kanna too, while blushing.

Fanon
Kannoko is the second most popular ship in Miss Kobayashi's Dragon Maid, right behind Kobahru, (Kobayashi and Tohru). While there are several things that aren't fully confirmed in canon, fans have ran with it and considered them to be in their own head canons. For example, it's not fully confirmed if Kanna recognizes Reiko's feelings for her; however, it's been theorized that, because dragons live longer than humans, and are much more intelligent than the average human being, that she does in fact realize it, and is just playing innocent for the time being. It's also been much debated whether she feels the same way; however, since she said at one point that she would like to have a similar relationship with Reiko that Tohru has with Kobayashi, fans have taken that to mean that she does does harbor romantic feelings for Reiko.

Some people have called the ship 'pedophilic' since Riko is a child mentally and psychically, while Kanna has the appearance of a child, but is most likely over 7000 years old.
