Kainess

Kainess is the slash ship between Michael Kaiser and Alexis Ness from the Blue Lock fandom.

Canon
Michael Kaiser and Alexis Ness are both U-20 Regulars playing for the German Football team, Bastard München.

Their first introduction depicts the two as somewhat close, Alexis often giving Michael what he requests, acting as a loyal servant to Michael. We see their first proper interaction after Alexis comes following behind Michael after he had intercepted Isagi's kick. When Isagi threatens Michael, he requests for a handkerchief from Alexis.

In their matches, Alexis's plays are often and nearly always, to pass to Michael for him to score, shown in the matches against F.C BARCHA, Manshine City, and Ubers.

During the match against F.C BARCHA, Alexis questions and insults Kunigami after he had missed scoring, claiming that if he had passed to Michael instead, they would of scored. This shows how loyal Alexis is to him, to the point where he would insult people who didn't follow the standard Bastard München rule to follow Michael. Kunigami tells him to piss off, calling him a boot-licker.

We see more of Alexis passing to Michael, complimenting him after he had scored and tied their game 1-1.

After the match against Manshine City, Alexis goes to question why Isagi had passed, insulting him because he couldn't go up against Michael to score his own goal. Isagi calls him "Kaiser's stupid lackey" in response. Before Alexis can continue his arguement with Isagi, Michael comes and grabs Alexis head, pushing it down. He holds Alexis's head while he talks with Isagi, him obviously being in pain, letting go after he was finished.

Later on, we can see Alexis give Michael his sunglasses and his drink. Michael begins to question him on why he joined Bastard München, Alexis responding. Michael then splashes his drink onto Alexis. After he had claimed that "Yoichi was big enough to eat", Alexis pardons himself to leave. In a fit of jealousy, he internally curses Isagi, questioning to himself why Michael was more interested in someone else.

When the match against Ubers start, We can see Michael and Alexis working together with Grim, attempting to help Michael score the first goal. After Isagi manages to get the ball, Alexis tries to throw him off his center of gravity by bumping into him, attempting to not let him score with his direct shot. But Isagi shows them his new lefty shot. This was an attempt to at least impress Kaiser by beating Isagi for once.

After Ubers score again, Alexis begins to doubt his abilities, when Michael comes in and grabs his head. But this time, it seems more gentle then before. He tells Alexis to try and get Lorenzo off him, in which Alexis obliges.

Fanon
When they were first seen, their subtle hint gained a considerable amount of shippers. It only grew further as the chapters went on, as we see more of Alexis's devotion to Michael. Most opposing shippers see it as toxic, as Alexis's kindness to Michael is requited with a cold attitude. People often depict it as a 'Master-Servant' Ship Trope.

Kainess is Michael's 2nd most popular ship on Ao3, and Alexis's most popular. Its mainly rivaled by Kaisagi.
