Matsuri

Matsuri (マツリ) is a girl who was abandoned by her father and lives "outside the wall." She rummages through the trash that ends up scattered outside the wall to find valuables that she can use and trade for food.

Appearance
Matsuri is a girl with yellow hair and light brown eyes. She is missing her left arm in an above elbow amputation and uses a prosthetic to replace it. She wears a white dress shirt, a black hat, black pants, brown shoes, and a brown glove on her prosthetic hand. In episode one, she wears a gray newsboy cap and a olive green coat.

Personality
Matsuri has a straightforward and pragmatic personality. She seems bad at lying. She is stern to children, but genuinely cares about their well being and is concerned if the children she takes care of can survive without her. She dislikes the idea that she was abandoned by her father. She hates vegetables, such as beans.

The episode opens with Matsuri having a dream about her younger self and her father who wears a necklace with a black key on it. She is holding his hand (with her right) as theya have a conversation with each other. He suddenly turns into scraps and fades away from her hand's grasp as she suddenly wakes up from her dream.

Matsuri tries to haggle with a man for food, complaining that his rates have gotten more expensive, stating that what she brought him should be worth more. She tries to negotiate by asking him to take whatever he likes and to give her three potatoes and sugar instead. He replies stating that it has been harder for people to get by as of late, and offers her beans instead of sugar, which she declines by stating that she hates vegetables.

The man compliments the vast amount of items Matsuri brought. She replies by saying he could get them himself if he visited the wall. He admonishes her by stating that he values his life too much to do that. She is left with one piece of yellow candy, murmuring to herself that sort of attitude is why nothing has changed.

Later, she is getting maintenance done on her prosthetic arm and finds two boys arguing with each other outside, breaking up the fight by hand chopping one on the head. The boys were talking about they needed to go to the wall, but one was too afraid to go because it is dangerous. She states that if they're too afraid to do anything, nothing will be left by the wall to trade and they won't be able to survive. Matsuri voices concern for the boys, wondering if they'll be able to take care of themselves if she is gone.

After maintenance is done on her prosthetic, Matsuri has a conversation with the technician, stating that no one else visits the wall and that someone has to do it. The technician asks why she's being so reckless, and she states that she's been having dreams about her father, wondering why he "threw her away", stating she doesn't mind the life she has outside the walls but hopes to find a way inside to find the answers she's seeking.

Matsuri scrounges around the walls, looking for items she can trade. She finds an empty jar of black beans and throws it away. She looks in the direction she threw it and finds Aizen sleeping in a pile of trash, wondering if he's alive. She crouches in front of him and tries to place the piece of candy she received earlier in his mouth, when he opens his eyes and places his hand on her chest. He asks her if she knows anything about his key, and her father's necklace immediately comes to mind, unsettling her.

Matsuri tries to leave Aizen behind, but he follows her, asking her what she was doing there. She states that she rummages through the trash that ends up outside the walls looking for things she can use and trade for. Aizen asks her about the key again, and she poorly lies, saying she knows nothing, but he doesn't believe her.

Eventually, Matsuri leaves Aizen behind and tries to head home when an armed man in a group shoots at her, but misses. Aizen appears again. She watches him come out seemingly uninjured as he flicks the bullet back at the gunman, and she seems startled, wondering what he is.
