Senruri

Senruri is the het ship between Senku Ishigami and Ruri from the Dr. Stone fandom.

Canon
Senku and Ruri are friends and allies in the Kingdom of Science. Senku first hears about Ruri when he first meets her sister, Kohaku, who mentions she had a sister who is terminally ill. When both Chrome and Kohaku mention how Ruri was the one who taught them Momotaro and "complicated" words, Senku starts to get interested in her and is determined to make the cure for her.

Determined to help cure Ruri, he joins the Grand Bout tournament to become the Village Chief, increase his Kingdom of Science and, more importantly, save her life. Chrome was supposed to win the tournament at first, but he ended up fainting, relieved after the battle because he knew Ruri would be safe in his hands. As a result, Senku ends up being the victor, shocking everyone. Ruri approaches him, and the two speak to one another for the first time in S1 EP16.

Since the rules of the Grand Bout Tournament stated that the winner of the Grand Bout would have to marry Ruri, they both get married. Before the Kingdom of Science could at least rest for a while, Ruri starts to cough very badly, and Senku knew there was no time for rest yet and needed to act quickly to create the "cure all drug" to find out what illness she had, the village insists they must celebrate the marriage, as mentioned earlier, there was no time, he divorces Ruri shortly after and takes the alcohol given by the village and runs away from the village to create the antibiotic.

Fanon
The ship is known for having the world's fastest divorce on earth as their marriage only endured few seconds for Senku's benefit. It turned out to be funny for the fans, and hilarious since Senku kept his arrogant nature instead of getting carried away for someone like Ruri. The lack of romantic attraction on Senku's is also part of the few reasons the divorce moment was understandable, often being head-cannoned by fans as aro/ace. However it does not take away from the fact that Ruri and Senku might be canon in the future, as fans hope for Senku's reconsider the divorce and marry Ruri now for real.

It's rather preferred as romantic, but there are fans who want them to just remain as friends, as Senku did all possible to save Ruri even not knowing her for much time. Ruri is also one of the love interest candidates for Senku to fans, but as said, due to the seemingly lack of romantic attraction towards people in Senku's part, for now they stay as good friends and allies.

Aside from that, Senku and Ruri pretty much have cute interactions and a headcanon was made where it suggests Ruri may have once harbored feelings for Senku as a child when hearing the stories of him in the Hundred Tales.

The ship is not quite popular in the Dr. Stone fandom, as there is barely any content for them. There are also rival pairings. For one, it is Senku and Kohaku, Ruri's sister. Next, people also ship Senku with Gen while Ruri is shipped with Chrome, as the two are childhood friends and are likely canon in the series.
