Rodney is a soldier who joins Touri's squad early on. They bond and become buddies. They even go on a date together at one point, though they both claim it's platonic. Rodney quickly becomes an existence Touri depends on to a huge extent.

At one point, Rodney volunteers to be a decoy on a su*cide mission in order to keep everyone safe. Touri volunteers to join the decoy unit as a result. They're both mortally wounded and, in order to keep from sharing another tragic secret, Touri confessed to him as he lays dying against a tree. They have an impromptu marriage before he dies, her first kiss being one that tastes of blood. Touri then straps Rodney's body to her back, drags herself to a river, then throws herself into it so the enemy can't desecrate Rodney's corpse and can't have their way with her. Her body belongs to him now, after all. (F*cking beautiful scene btw, had me in tears)

She survives, of course. Fast forward a bunch and she meets Rodney's little sister, Linalee, who he had talked about a lot before. She's the sole survivor of her town after they got attacked by an enemy army. Touri wants to get to know her since she's technically family, but Linalee is prickly because she's in mourning. However, after some effort, Touri gets through to her and they become much closer. Linalee even starts calling her Onee-san. Then the enemy attacks and Linalee gets horribly killed. Cue Touri completely falling apart.

Touri herself starts off quite weak, not even capable of casting Heal despite being a medic. She quickly picks that up though alongside the Shield spell. She also trains to have the endurance to keep up with the assault platoon she's assigned to. Because she has excellent battlefield awareness, she also picks up some training as a scout. Eventually, she trains under a defense platoon and finally learns how to shoot and Shield properly.

From her past life, she also has some experience with leading squads and basic tactics, though it takes time before she can translate that to a real war. Quite frankly, her tactical capabilities as a battlefield commander are likely just as good, if not better than, the best two commanders in the story (both of whom view her as monstrously skilled and really want to recruit her for themselves), but her low self-esteem, modest nature, and general pacifistic personality means she doesn't think of herself as that skilled. It's also not a skill she really gets to show off until way later in the story.

Her best ability however is her danger sense. It's basically supernatural with how good it is. At the right times, she can know what actions she should or shouldn't take entirely based on her danger sense. It takes a while before she really starts showing it off, mostly because she spends most of the story in the field hospital healing, but when she pops off she can really pop off. This becomes especially useful later on when she finally stops being a medic and gets assigned her own company to lead.
