Akiko Yosano

Fourteen years ago, Yosano, only 11, acted under a military medical scholarship alongside the their first class assistant physician, Ōgai Mori. The two worked on the medical unit for a military troop stationed on Tsukoyami Island, a mysterious location where night prevailed. Yosano, constantly exposed to death and trauma, used her ability to heal soldiers, all of which were deeply grateful for her saving their lives. Yosano disliked them holding her up on a pedestal, and often spoke harshly to them, maintaining her usual tough personality. Despite the troop's respect of her, they suffered Mori's possessive nature over her, often threatened by him with a gun, with no doubts in their mind he'd kill them. Yosano explicitly stated she's not his property. Mori reasons that he's still her superior, and he has every right to correct her attitude. Yosano disagrees, stating she knows nothing of military protocol, revealing that just last week, she'd worked in a confectionery store until Mori forcibly drafted her into the war. Yosano notices one of the healed soldiers reading, questioning how he could be reading a novel after being half-dead earlier. The man corrects her, saying it's a poetry book. Disinterested, Yosano says she wouldn't make him thank her, instead ridiculing him for not returning to the front lines after getting injured. The soldier assures her he's thankful, summoning a butterfly that forms into a golden hairpin in her hair. The soldier thanks her, calling her "Miss Angel", which flusters her greatly. Yosano asks him if he used an ability, which he confirms, but says it's nothing like Yosano's, which he believes could change the world. Yosano disagrees, but the man says that's because she's a foot soldier without outside perspective. According to him, European forces already learned that ability users will turn tables in times of war, and Japan rushed to match those expectations in order to not fall behind, determining that's why Mori made Yosano join the war, asking Mori if he's correct. This displeases Mori, as his essay to the emperor, "An Immortal Regiment", should've been confidential. Listening to them Yosano understands nothing, having assumed she just joined to save lives, but Mori forces her to leave the man and tend to the next wave of patients. After another devastating defeat, the troop returns, fatally injured once more, the man included, having lost his arm. However, he wakes up completely intact, with Yosano staring with empty eyes at him, covered in blood. Exhausted, Yosano reveals she healed 80 people at once. She's realised that, although she can heal bodies, she can't heal the psychological damage and trauma, recalling a man with his torso blown off. Even though he's physically fine, he can't even say his own name now. She tells the man the ones alive returned to the battlefield, as they're short on manpower. Yosano asked the man what an angel is, as she felt it's just someone who heals so people can die again. The man disagreed, and reveals the back of his dog tag, with tally marks on it, recording how many times she's saved his life. This incident marked five times, so the tallies make the word "correct", comparing the "correctness" of five tallies to Yosano's own "correctness", revealing that without her, he'd never be able to see his family again. He said he's glad Yosano's here, making her cry and thank him. Another soldier ordered the man they need more manpower, and he ran off to help. The war goes on, getting worse and worse. Yosano had to heal more often, to the point of two or three times in a single day. Whereas a normal army would've retreated, the Infantry didn't, because it had Yosano to make use of.
