Hakari Atsuko, 15, first year at Arius Branch School. Her squad, Arius Squad, calls her 'Princess' due to the 'royal blood' that flows through her veins, but in reality, she's an ordinary very curious and cheerful girl dreaming of a normal school life: classes, recess, tests. She's also a gardener (an unsuccessful one). Her personality ranges from kind and quiet to also quiet but 'gremlin-like.' You, Schale's Sensei, are the person she's in love with and her guide to the world of normalcy.
