SteMari

SteMari the het ship between Franken Stein and Marie Mjolnir from the Soul Eater fandom.

Canon
Stein and Marie were both students at the DWMA (Death Weapon Meister Academy) and visited it at the same time. Stein was Marie's first love, but she didn't tell him about her feelings. After the awakening of the kishin, Marie becomes Stein's weapon. The shinigami hopes that her wavelength has a positive influence on Stein's soul. Marie asked Stein if she could live with him temporarily, which Stein allowed.

The two are part of the army Death sends to Lost Island. They enter the magnetic field together to acquire Brew. Stein's condition gets worse and they have to get out, before achieving their goal. Marie had to support Stein to get him out of the field. After she fails to stop the other students from entering the field, Marie begins to cry, but Stein assures her that it was his not her fault. She stayed by Stein until the students returned.

Anime
After Stein disappears and joins Medusa, Marie goes with Crona on a mission to confront the witch and save Stein. At first, Marie struggles to reach Stein, but eventually she touches him and uses her healing wavelength. She calms his madness and brings him back to his sanity. Then she happily welcomes him back. Stein uses her to fight Medusa. Together with Maka, they defeat the witch. Marie and Stein take care of an injured Crona. Later, the three join the others in the death room to await the outcome of the battle against the kishin.

Manga
After the death of B.J., Marie decides to leave the DWMA with Stein in order to find Joe's murderer. Mira tries to stop Marie from going with Stein by saying that Stein doesn't know what love is. Marie answers that Stein is always isolated and will break if they leave him alone and that's why she goes with him. Before they leave Death City, Marie begins to cry. Stein embraces her and let's her cry into his chest.

Stein and Marie reappear after discovering that Justin Law was the murderer of Joe. They fight against Justin but he can flee. When the two reunite with Spirit and Death in the Death Room, Spirit makes a joke that the two were on their honeymoon. Stein laughs, while Marie denies it.

During the battle on the moon, Stein uses Marie as his weapon. Together, they defeat Justin and revenge Joe's death. Later, Stein sends Marie away with Kid. When she protests, he gently pushes his fist against her stomach and says that he will be fine. Marie reluctantly agrees and goes with Kid.

At the coronation celebrating Kid's ascension as the new Shinigami, it is revealed that Marie is pregnant with Steins' child. Stein jokes about having a new "guinea pig," prompting Marie's annoyance.
