Tsumary

TsuMary is a femslash ship between Mary Saotome and Tsuzara Hanetemari from the Kakegurui fandom.

Canon
Mary Saotome never liked Tsuzura, as Mary was envious of Tsuzura's wealthy background. Tsuzura is also a very generous person, straight away lending her money to Mary. It was said that her gambling skills are pretty low. Spending a lot of time with Mary made her a more confident person and a better gambler. She feels strong admiration towards Mary and looks up to her. Tsuzura even considers Mary “her prince”, which seems to imply her feelings are romantic in nature.

Kakegurui Twin
Tsuzura happily greets Mary at the school entrance. After explaining the prevailing rules and traditions within the academy, she warns Mary to be careful, as transfer students are often targeted by the other students, as they're not used to gambling. Their conversation is interrupted by Kokoro Aiura, who introduces herself to Mary and proposes her a match. When Mary asks why she can't talk with Tsuzura, Kokoro explains that this is against the rules, pointing out that Tsuzura is a housepet and has no human rights whatsoever. Kokoro then proceeds to pour out water on Tsuzura's head and forces her to leave class during her match with Mary. Later, when Mary lost to Kokoro, Tsuzura gave her money in order for a rematch, so that Mary wouldn't become a housepet too.

After winning a rematch, Tsuzura and Mary become good friends. Tsuzura sees Mary as “her prince”. Mary also feels sorry for her. So they looked for a gambling den to take over and get more money. They chose the most unpopular one, which currently belonged to Yukimi Togakushi. But before they could talk about it, Sachiko Juraku entered and declared that the den would be closed entirely. But Mary requested a gamble, to Tsuzura's surprise. Mary ended up winning and together with Yukimi they host gambling sessions, where they dress up as maids. Tsuzura was worried when Aoi Mibuomi came and wanted to play a game. But Aoi simply wanted to get in touch with Mary.

During the Coupling party event, Mary suspects Tsuzura might have betrayed her and initially cuts her out of her group. Tsuzura is devastated, but she still trusts Mary and keeps gambling even if she's not aware of her group's strategy, knowing that Mary will definitely find a way to win. After the game, Mary apologizes to Tsuzura and Yukimi for not trusting them the entire time. Tsuzura immediately hugs Mary and starts crying, telling her she feels sorry for always causing problems for her. She's relieved Mary has not abandoned her.

Kakegurui
Tsuzura appears to not be at the academy anymore. Before she left, Tsuzura gave Mary her flower hairpin so she would remember her. After Mary's meeting with Kirari, Mary was reflecting about how much she despises the housepet system. Mary is seen clutching the hairpin, thinking of Tsuzura and missing her. Whatever happened to Tsuzura must have had something to do with Kirari and thus Mary is getting angered.

Fanon
This ship is not as popular as Yumary or Meariri, however it is the main ship that is teased in Kakegurui Twin. Tsuzara and Mary have appeared together in several pieces of official art. Many Kakegurui fans seem to enjoy this ship, as it is comparable to Meariri, where Tsuzara is similar to Ririka. Many fans also like to speculate what exactly led Tsuzara to leave Hyakkou, and why Mary is still in possession of her hairclip.
