Mary Saotome (also often referred to as Meari Saotome) is a deuteragonist from Kakegurui and also the main protagonist of the spin-off series Kakegurui Twin. She's a student at Hyakkaou Private Academy and a classmate of Yumeko Jabami and Ryota Suzui. She is the first character in the entire series that challenges Yumeko and loses against her.


Mary is a girl of average height with long blonde hair styled into two ponytails that are tied with black ribbons and dark yellow eyes. She wears the standard Hyakkaou Private Academy issued school uniform. A red blazer with black trim around the cuffs and collar and gold buttons. Beneath the red blazer, she wears a white button-up shirt and black tie. She wears a gray pleated skirt, black colored stockings and regular brown loafers with black soles.



Mary mocking Yumeko for getting cold feet

At first, Mary is shown to be incredibly sadistic and twisted such as how she treats Ryota Suzui, her classmate after he turned into a “housepet”, due to his low social status within the academy and is shown cruelly taunting her fellow opponents during their gambling matches. She's also shown to be extremely egotistical both in and out of matches, often being confident in her victory. Mary also possesses a habit of mocking her opponents and laughing at them, especially when match seems to be her win. 


Mary after losing everything

After losing to Yumeko Jabami and experiencing the life of being a housepet, Mary became desperate to regain her status within the academy, having no other goal in her mind. Soon after being humiliated Mary eventually lose her pride, having a mental breakdown during the match against Yuriko and falling into the state of grief and shame. After regaining her status, she seems to no longer be this arrogant and cruel, sometimes being only nettled by Ryota's cowardice or Yumeko's reckless behavior. But she does care for her new friends now. She is still as cunning and intelligent during matches though. She now also hates the council even more and wants to make them pay for not treating housepets as human.


Mary tormenting Ryota

It was hinted that she has feelings for Ryota, which may be the reason why she was treating him this horribly. Mary also seems to be jealous of Yumeko, as her growing popularity was the cause of challenging her in the first place. Her reaction when Ryota confessed his feeling towards Yumeko during their match against Kirari Momobami, only confirms that she has a crush on him.

In Twin, it is revealed her family is not wealthy and she is attending Hyakkaou Private Academy on a scholarship. Her goal has always been to become a true winner in life. She feels great pride in her intelligence and gambling abilities and hates when people look down on her for her financial status. During the prequel, she's noticeably less ruthless. Since Tsuzura is absent from the main story, Mary is shown to still keep her hairpin and holding a grudge against the Council. She seems to be sad and angry about whatever happened between the end of the prequel and the start of the main story. Her mean and arrogant demeanour might have possibly be to supress her sad feelings.

Mary winning due to her cheating

Mary is seen at the start of the series winning a poker match against Ryota Suzui, who ends up owing him a debt of 5 million yet. Unable to pay it, Suzui instead becomes her pet in the end and treats him in an inhuman manner as she is seen commanding Suzui to bring her food and using him as a footstool when she says that her legs are worn out. When Yumeko Jabami transfers into their class, she is instantly healous of her popularity and her getting close to Ryota. She pretends to challenge her to a simple friendly game she called Vote Rock-Paper-Scissors. But Mary was actually cheating and wanted to turn Yumeko into a housepet.


Mary defeated by Yumeko

When Yumeko bet only small amounts she left the results up to chance, but when the stakes got higher she used her cheat to win. She was amused by how naive Yumeko was betting and looked forward to destroying her. However before they played their final cards, Yumeko revealed that she figured out how she cheated. Although Mary was a bit unsure now, she was still confident enough to win. But Yumeko managed to win against her. Mary is extremely desperate and states she can't repay her. Yumeko says its fine and she gives up the debt, since the game was so fun. But everyone already lost some respect towards Mary. Unfortunately for her the rankings of how much each student donated to the council were revealed the next day and Mary ranked in the last 100 due to her recent loss.


Angry that she is now a houspet

So the next day at school, Saotome's desk is seen ruined with graffiti and has a broken doll on her on top of it that resembles her. Concerned, Jabami questions what happened to which she tells her to shut up and it all happened because of her losing to Jabami. She is still full of anger, but already gets ordered around by her former friends to clean up. She feels pity for herself and cries why this has happened to her. As a last effort Mary gambles against Yuriko Nishinotouin, hoping to be able to repay her debt. Near the end of the game, Yumeko just happens to come by, angering Mary even more. But she loses and owes the Council even more money which has now completely ruined her. She knew that she probably would have been able to repay her previous debt, but just had to take the risk.


Mary tricking Jun

She also receives a lifeplan, which the Student council arranged for her. It states that she must marry a politician. When consulting Runa Yomozuki about this, she just laughs. Mary is furious and doesn't want to accept it, but has no choice. Mary then enters the Debt Settlement game. Although the pairings for the game (Two-Card Indian Poker) seem to be random, Mary curses that her assigned partner is Yumeko Jabami, who recently became a housepet in one game. However the two concoct a plan to get out of debt by switching their declarations and working together during the game itself. During the game against Jun Kiwatari their plan works perfectly and he didn't look through it until the end. Mary wins and is able to free herself from her position.


Mary baffled by Yumeko's friendship

Mary then becomes better friends with Yumeko and accompanies her to most gambles and cheers her on. At first she is embarassed to admit, that she had fun playing with her especially when Yumeko gets a bit too close to her. But she does start to like her even if she still believes her risk taking to be reckless.She then talks to Kirari Momobami, stating that she wants the housepet system to be removed. Kirari points out that she hasnt always been thinking that way and treated other housepets badly herself.

Mary wants to gamble with her and only if Ririka wins, will she accept her as a partner. She did win which bugs Mary. But steadily they do develop trust in each other to the point, where Ririka actually takes her mask off in front of Mary. Mary is also invited to the auction and takes part in it.
