Nuola has wanted to achieve perfect precision in about everything she does since she knows about herself. That even manifested into her weapon form, as she is a ranged multi-weapon (Bow, Crossbow and Slingshot).

They moved to Death City as her father became a kishin and had to be eliminated. Not that Nuola minded that as it means she could attent the DMWA™️.  Nuola is often underestimated due to their childish color choices, especially because her weapons have a toy-like look. Meisers often have trouble with her because she demands to be used precisely and up to her upmost potential, she had issues with grades and with Soul Resonance.
