MeiVoid

MeiVoid is the femslash ship between Raiden Mei and the Herrscher of the Void from the Honkai fandom.

Canon
Mei and the Herrscher of the Void, aka Sirin, are naturally enemies due to the Herrscher's desire to take control of Kiana and destroy humanity. Sirin is aware of Mei's romantic relationship with Kiana, and so for her amusement, her interactions with Mei are can be quite flirtatious. To break Kiana's resolve, Sirin used Mei's image several times, such as in Chapter 2 and in Arc City.

The two directly confronted each other in Chapter 8, as Theresa, Himeko, and Mei attempt to save Kiana from Otto's grasp. By the time they arrive however, they are too late, and Otto has allowed the Herrscher to take control. Mei falls directly into Kiana's arms and asks if she's alright. She then witnesses the Herrscher of the Void take control of Kiana's body. Sirin sinisterly replies with romantic words, referring to Mei as her "other half." Determined to save Kiana, Mei directly battles Sirin with the help of the 3rd Herrscher. But she is no match for Sirin, who gains the upper hand and starts strangling Mei. Mei briefly brings Kiana back with a touch, before the Herrscher takes control again. Mei watches helplessly as Sirin easily defeats fleets of AE mechs and summons the Honkai beast Benares.

In Chapter 9, Theresa helps Mei out, and Bronya joins them to face the Herrscher together. They seemed to have the upper hand at first, but Sirin easily overpowered the Oath of Judah and Star of Eden. With a goal to make Kiana suffer, Sirin targeted Mei first. Once again speaking to her with twisted romantic words, Sirin took the Gem of Conquest from Mei and relished in her amplified power. Fu Hua then arrived to fight off the Herrscher, giving Theresa, Mei, and Bronya the opportunity to retreat.

Fanon
Although it is a well-known ship thanks to Sirin's flirtatious remarks towards Mei, MeiVoid is a rarepair in the fandom. It is seen as a dark version of Kiamei, with an intriguing dynamic where Mei has to deal with her enemy using the body of her lover while Sirin sees her as an amusing plaything.

Some also ship Mei with the original Sirin. Though this is generally not favored because on top of having no interactions, the Sirin of Second Eruption is a child while Mei is a young adult.
