Sena's overprotective and motherly childhood friend. Mamori's mother met Sena's mother in a cooking class, and Mamori and Sena have been friends ever since. Her mother is half-Japanese, half-American which makes Mamori 25% American and 75% Japanese. Mamori has been protecting Sena from bullies since primary school, to the point that Sena has grown up never having to stand up for himself. Mamori joined the American Football club to watch over Sena and prevent any bullying by the other members (particularly Hiruma). Despite her 'joining the American Football club just to protect Sena's claim, she eventually becomes an excellent manager who knows the rules inside and out and makes up strategies for the team (since she has trouble with computers, she does it all on paper—super-analog). Mamori does not recognize Eyeshield 21 until he reveals his identity during the match against the Bando Spiders team. A lovely girl, Mamori excels in all her studies except art, which she is horrible at, and helped Sena with his high school entrance exam. She is also a member of the school's disciplinary committee. Though she is constantly butting heads with Hiruma, she eventually sees a softer side to the Devil Bats' quarterback.
In the anime, Mamori tries to discover Eyeshield 21's identity, mostly because when she is making the telephone contact list, she needs a number to get in touch with him. Hiruma gets around this by assigning himself the responsibility of relaying all messages to Eyeshield 21. In the end, even when Sena is forced to remove his helmet to save her from the Zokugaku Chameleons, his identity remains secret to her, thanks to her own disbelief and Hiruma's tricks. She eventually gives up trying to learn who he was. Mamori has been known to block bullets from the trigger-happy Hiruma at times (once when they are aimed at Sena for daydreaming, and again after the completion of the Death March when everyone falls asleep in their hotel room).
Mamori learns about Eyeshield's identity in chapters 154 and 155, when Sena removes his helmet in front of her. After Sena apologizes and takes to the field, Mamori says that she should be the one apologizing. Seeing him run out of the tunnel finally made her realize that he is no longer the a boy and that she has been babying him all this time. Mamori joins the Devil Bats on the field, introduced as the team's manager, signal-relay and "expert at high-speed snack eating" (much to her obvious annoyance).
Prior to the start of the Kanto Tournament, Mamori gets a haircut, saying that she wanted a change of pace. Ishimaru changes his hairstyle, but goes largely un-noticed, as usual.
Mamori's relationship with Hiruma changes over the course of the story. Like she does with Sena and other members of the team, she wants to take care of him and is often worried over his injuries. In chapter 205, she tries to talk to him about how hard he pushes himself. After telling him that he doesn't need to worry so much, she secretly smiles to herself. Though Hiruma is likely aware of her feelings, he often chooses to ignore her kindness, and sometimes changes the subject in order to avoid an awkward moment.
Before the match with Hakushuu Dinosaurs, Hiruma given Mamori instruction letter which contain how the play should be continued if, by any chance, he got injured. However, in tears, Mamori ripped the letter, saying that she doesn't want to see him injured, and she believes the team will do everything they can to protect him. However, when Hiruma got really injured and can't continue to play, she reveals that she secretly tapes the letter, and when reading it, decides to let Sena play as quarterbacks as Hiruma's replacement, by saying nothing about it, and letting Sena take the decision by his own will.
