Qmai

Maitaro is the het ship between Mai Tsurugi and Q-taro Burgerberg from the Your Turn To Die fandom.

Canon
Mai is paired with Q-taro as his support.

After searching all the rooms on the fourth floor, Mai is seen searching the locker room with Q-taro.

Eventually, Sara finds four colored books and places them back into the shelves in the library. This opens up a passageway to a stadium-like area where Midori waits. All of the pairs arrive and confront Midori, when Kanna/Shin realizes that Mai and Q-taro aren't with them. Everyone rushes to the security room and finds Mai stabbing Q-taro in the Doll Graveyard. She reveals that the dummies' task is to kill their partner before Midori dies in order to survive. However, she failed to actually kill him and ended up getting knocked unconscious.

Like the other dummies, Mai's requirement for survival is different from the humans participants. To live, you must murder your master before the Floor Master, Midori dies. Mai took the opportunity to talk to Q-taro in the Graveyard after everyone went off to track down Midori. Mai then stabbed Q-taro in the back with the knife from the Boxing Ring mini-game earlier in the chapter. Mai cheerfully celebrates, explaining to Q-taro her goal. Q-taro, still having enough strength, knocks her out. He doesn't kill her because he felt bad for her situation as support. Mai would always flirt with Q-taro to get his trust and be ignored more easily. It's unclear if Mai actually wanted to be friends with Q-taro since she gets knocked unconscious. After Q-Taro states that they're all allies and that he doesn't hate her for stabbing him, Mai is confused and seems to feel very guilty. She is later shown to be genuinely kind and thankful to Q-Taro and they end up forming a close bond.

Fanon
This ship has become quite popular after the events of Chapter 3-1a and 3-1b. Though originally it might've been viewed as toxic, as of 3-1b, the ship has gained a lot more popularity.
