MomoMai

MomoMai is the femslash ship between Mai Zenin and Momo Nishimiya from the Jujutsu Kaisen fandom.

Canon
Mai and Momo are both students at the Kyoto Prefectural Jujutsu High School. The two are shown to be close friends along with Kasumi Miwa.

During the exchange event Momo is fighting Nobara and is saved by Mai's bullet.

In a Juju Stroll Mai and Momo steal Kasumi's vegetable stash and eat together.

Following Mai's death, Momo is shocked and says "that's why I told you not to go!" Maki then hands off Mai's body to Momo stating "she's in your hands now."

The two refer to each other as their first names and Momo calls Mai "Mai-chan" implying they must be close.
