Yurika

Yurika is the femslash ship between Monika and Yuri from the Doki Doki Literature Club! fandom.

Canon
During Act I of the game, Yuri and Monika seem to be on good terms, though there is not much interaction with either of each other, they are similar in terms of looks, both of them having long hair. They are also the more mature girls of the four club members. Act II Yuri and Monika are both yanderes, after Monika tampers with Yuri to make her less likeable to the player. Of course, if the player had not stepped in, things could have turned out differently and they both could have ended up together.

Fanon
Most of the fandom that ships Yuri x Monika ships them because of Yuri's yandere like nature in the second act of the game. These fans think that both Yuri and Monika are compatible, and some ship Sayori x Natsuki. The ship is one of the less popular ones, being behind ships like Natsuri and Saysuki. Ships like this are controversial given what Monika did to the other characters in the game. Much of the community still remains divided on ships like these.
